How to survive a PhD viva: 17 top tips

Just handed in your PhD thesis? Now it’s time to plan for the next hurdle: a viva. Academics offer their advice on how to best prepare

Finishing your PhD thesis: tips from those in the know
The key to a successful PhD thesis? Write in your own voice
PhD: so what does it really stand for?

H anding in your PhD thesis is a massive achievement – but it’s not the end of the journey for doctoral students. Once you’ve submitted, you’ll need to prepare for the next intellectually-gruelling hurdle: a viva.

This oral examination is a chance for students to discuss their work with experts. Its formal purpose is to ensure that there’s no plagiarism involved, and that the student understands and can explain their thesis. It involves lots of penetrating questions, conceptually complex debates and is infamously terrifying.

How can PhD students best prepare? We asked a number of academics and recent survivors for their tips.

Preparing for the viva

1) Check your institution’s policies and practices

Institutional policies and practices vary. Find out who will attend your viva (eg will a supervisor attend, will there be an independent chair?) and what their roles are. Penny Tinkler and Carolyn Jackson, authors of The Doctoral Examination process: A Handbook for Students, Examiners and Supervisors

2) Re-read your thesis – and keep up-to-date with research

Don’t underestimate the amount of time the examiners will have spent reading and thinking about your thesis – however, you should remember that you are still likely to be the “expert in the room” on this particular topic. Check to see if any relevant recent papers have emerged since submitting the thesis and, if so, read these. Dianne Berry, dean of postgraduate research studies, University of Reading

3) As an examiner, you tend to stick to things you’re an expert in when driving the questioning

Your viva panel will consist of an external expertise in your subject area and an internal which may be in a subject field associated or directly related to yours. The external examiner is the one who mainly calls and fires all the shots and so it’s pretty important to have a knowledge of their published contributions, especially those that are related to your thesis in any way. Dr Bhavik Anil Patel, senior lecturer in physical and analytical chemistry

4) Think about what you will or won’t defend

Consider carefully what you will defend to the hilt in the viva, and what you are prepared to concede. It’s important to defend your claims about the originality of the thesis and its contribution to knowledge. However, no research is perfect, and showing that you have considered what could have been done differently, or even better, is not a bad thing. Penny Tinkler and Carolyn Jackson, authors of The Doctoral Examination process: A Handbook for Students, Examiners and Supervisors

5) Draw up lists of possible questions – especially ones you dread

I collected questions from a bunch of different places ( listed here ) which I then tailored to my PhD. Somebody I worked with also recommended that I put together my 10 nightmare questions. I found this really useful, by writing down and thinking about my dreaded questions, they were no longer so bad – it was almost as if I’d faced the beast.

Generally speaking, I was able to predict the questions that I was asked. There were a couple that were unexpected but they were either conceptual points or based on literature that I just didn’t know. Richard Budd, research assistant, University of Bristol who sat his viva in summer 2014 and has blogged about the experience

6) It’s not like sitting at a laptop where you can edit a sentence as you go along

By the time you finish your PhD you’ll know your thesis inside out. One of the things you won’t be as practised at is talking about it. When I was preparing for my viva, I practised vocalising answers. It’s not a case of needing to learn to answers verbatim – this would only work as a technique if you could guarantee the exact way your examiner will ask a question – but it is about thinking about how you will articulate certain things. A viva isn’t like sitting at a laptop where you can edit a sentence as you go along. Richard Budd, research assistant, University of Bristol who sat his viva in summer 2014 and has blogged about the experience

7) Bring a printed copy that is exactly the same as that of your examiners

Ensure you and your supervisor have a printed copy that is exactly the same as that of your examiners (specifically the same pagination). Mark with tabs the key sections and highlight for reference important quotes and points you might want to refer to. If you have some key diagrams it may help to have these printed larger on A4 sheets that can be used in a discussion.

There is a chance, albeit slim, that an examiner will wish to see some piece of experimental data, software, or other supporting evidence. Have this all neatly archived and accessible. You can do this after submission. Anthony Finkelstein, dean of the UCL faculty of engineering sciences who has blogged about surviving vivas

During the viva

8) Get off to a good start

Give a few detailed answers in the opening 15 minutes, demonstrating knowledge, describing your thinking and working - then the examiners are likely to relax into the viva. If the first few answers are short and non-specific, not demonstrating knowledge, this can begin to raise concerns, and that can set the tone for the whole viva. This is avoidable. Rowena Murray, author of How to Survive Your Viva: Defending a Thesis in an Oral Examination

9) Prepare for the icebreaker

Every viva opens with that dreaded icebreaker that is supposed to break you in gently but often seems to be the thing that gets students into a pickle. It’s so basic, students almost forget about it. Most often this would be to give a five to 10 minute introduction to your work and your key findings. This is such a common question that not preparing for it would be silly. Dr Bhavik Anil Patel, senior lecturer in physical and analytical chemistry

10) Silence doesn’t mean bad news

Don’t assume that you will be given any indication of the outcome at the start of the viva. The examiners may or may not offer comments on the thesis at this stage and candidates should not interpret a lack of comments at this point as a negative sign. In some cases institutional policy prohibits it. Penny Tinkler and Carolyn Jackson, authors of The Doctoral Examination process: A Handbook for Students, Examiners and Supervisors

11) Don’t point out your own weaknesses

Avoid shooting yourself in the foot by highlighting the weaknesses in the thesis by being overly humble (eg “I didn’t think this would be an acceptable piece of research given the way I handled x or y”) or by saying what you “failed to achieve” or “did not manage to carry out in a robust manner” etc. Leave that to the examiners to pick up in their reading, they don’t need help. Dr Mariana Bogdanova, lecturer in management, Queen’s University Belfast

12) Don’t talk like a politician There’s a danger of trying to over-prepare. Don’t learn answers off by heart – it removes the spontaneity and is obvious to examiners. If a student has pre-prepared answers they become a bit like politicians, answering questions they weren’t asked rather than the ones they were. I have come across mixed views on mock vivas. Some people really like them – and they can settle nerves – but other times it can remove spontaneity and steal your thunder. Jerry Wellington, head of research degrees at University of Sheffield and author of Succeeding with Your Doctorate

13) You may need to move from friendly questions to complex debates

Vivas can appear friendly and then suddenly go very conceptually complex. The language used is an alternation between accessible normal language and really specialised arguments. The student needs to be able to move orally between the two. Gina Wisker, professor of higher education and contemporary literature at Brighton University

14) If things get on top of you, use the excuse of having a look at the thesis

Make sure that before the viva you get plenty of sleep, eat properly and de-stress. If things get too much when you’re in there, use the excuse of having to look something up in your thesis. You could also pause and say “Can I write that down for a moment?” Stall for time until you get yourself back together again. Gina Wisker, professor of higher education and contemporary literature at Brighton University

15) Focus on your contribution

One of the most important things that the examiners will be looking for in your thesis, is the “contribution to knowledge”. It is the contribution which makes your work doctoral level. Be sure that you understand exactly what your contribution is, and that you are able to express and explain it clearly and concisely.

Write it down in a paragraph. Discuss it with you supervisor and fellow students. Make sure that you can relate your contribution to other work in your field and that you are able to explain how your work is different. Peter Smith, author of The PhD Viva

16) Expect your viva to last between one and three hours

Students frequently ask how long the viva is likely to be. Obviously they vary. Discipline differences are important. Our research suggests that most natural and applied sciences vivas were completed in one to three hours, whereas arts, humanities and social science vivas were typically less than two hours long. In the natural and applied sciences 43% of vivas lasted two hours or less, compared to 83% in arts, humanities and social sciences. Penny Tinkler and Carolyn Jackson, authors of The Doctoral Examination Process: A Handbook for S tudents, Examiners and Supervisors

17) Enjoy it

The best advice I ever got was “Try to enjoy it”. It seemed ludicrous at the time, but I actually found myself really getting into the discussion as the viva went on. It’s one of the earliest chances you get to talk to someone who not only informed your research (ideally) but is also conversant with your own. It’s a great chance to explore the contours of your research – treat it as such, and it doesn’t seem quite so daunting. Michael James Heron, school of computing science and digital media, Robert Gordon University

What Is a PhD Viva?

A viva voce , more commonly referred to as ‘viva’, is an oral examination conducted at the end of your PhD and is essentially the final hurdle on the path to a doctorate. It is the period in which a student’s knowledge and work are evaluated by independent examiners.

In order to assess the student and their work around their research question, a viva sets out to determine:

you understand the ideas and theories that you have put forward,
you can answer questions about elements of your work that the examiners have questions about,
you understand the broader research in your field and how your work contributes to this,
you are aware of the limitations of your work and understand how it can be developed further,
your work makes an original contribution, is your own and has not been plagiarised.

Note: A viva is a compulsory procedure for all PhD students, with the only exception being when a PhD is obtained through publication as opposed to the conventional route of study.

Who Will Attend a Viva?

In the UK, at least two examiners must take part in all vivas. Although you could have more than two examiners, most will not in an attempt to facilitate a smoother questioning process.

One of the two examiners will be internal, i.e. from your university, and the other will be external, i.e. from another university. Regardless, both will be knowledgeable in your research field and have read your thesis beforehand.

In addition to your two examiners, two other people may be present. The first is a chairperson. This is an individual who will be responsible for monitoring the interview and for ensuring proper conduct is followed at all times. The need for an external chairperson will vary between universities, as one of the examiners can also take on this role. The second is your supervisor, whose attendance is decided upon by you in agreement with your examiners. If your supervisor attends, they are prohibited from asking questions or from influencing the outcome of the viva.

To avoid any misunderstandings, we have summarised the above in a table:

Note: In some countries, such as in the United States, a viva is known as a ‘PhD defense’ and is performed publicly in front of a panel or board of examiners and an open audience. In these situations, the student presents their work in the form of a lecture and then faces questions from the examiners and audience which almost acts as a critical appraisal.

How Long Does a Viva Last?

Since all universities have different guidelines , and since all PhDs are unique, there are no standard durations. Typically, however, the duration ranges from one to three hours, with most lasting approximately two hours.

Your examiners will also influence the duration of your viva as some will favour a lengthy discussion, while others may not. Usually, your university will consult your examiners in advance and notify you of the likely duration closer to the day of your viva.

What Happens During a Viva?

Regardless of the subject area, all PhD vivas follow the same examination process format as below.

Introductions

You will introduce yourselves to each other, with the internal examiner normally introducing the external examiner. If an external chairperson is present, they too are introduced; otherwise, this role will be assumed by one of the examiners.

Procedure Explained

After the introductions, the appointed chair will explain the viva process. Although it should already be known to everyone, it will be repeated to ensure the viva remains on track during the forthcoming discussion.

Warm-Up Questions

The examiners will then begin the questioning process. This usually starts with a few simple opening questions, such as asking you to summarise your PhD thesis and what motivated you to carry out the research project.

In-Depth Questions

The viva questions will then naturally increase in difficulty as the examiners go further into the details of your thesis. These may include questions such as “What was the most critical decision you made when determining your research methodology ?”, “Do your findings agree with the current published work?” and “How do your findings impact existing theories or literature? ”. In addition to asking open-ended questions, they will also ask specific questions about the methodology, results and analysis on which your thesis is based.

Closing the Viva

Once the examiners are satisfied that they have thoroughly evaluated your knowledge and thesis, they will invite you to ask any questions you may have, and then bring the oral examination to a close.

What Happens After the Viva?

Once your viva has officially ended, your examiners will ask you to leave the room so that they can discuss your performance. Once a mutual agreement has been reached, which can take anywhere from 10 minutes to an hour, you will be invited back inside and informed of your outcome.

PhD Viva Outcomes

There are six possible outcomes to a viva:

Immediate award of degree: A rare recommendation – congratulations, you are one of the few people who completely satisfied your examiners the first time around. You do not have to do anything further at this point.
Minor amendments required: The most common recommendation – you obtain a pass on the condition that you make a number of minor amendments to your thesis, such as clarifying certain points and correcting grammatical errors. The time you have to make these changes depends on the number of them, but is usually one to six months.
Major amendments required: A somewhat uncommon recommendation – you are requested to make major amendments to your thesis, ranging from further research to collecting more data or rewriting entire sections. Again, the time you have to complete this will depend on the number of changes required, but will usually be six months to one year. You will be awarded your degree once your amended thesis has been reviewed and accepted.
Immediate award of MPhil: An uncommon recommendation – your examiners believe your thesis does not meet the standard for a doctoral degree but meets the standard for an MPhil (Master of Philosophy), a lower Master’s degree.
Amendments required for MPhil: A rare recommendation – your examiners believe your thesis does not meet the standard for a doctoral degree, but with several amendments will meet the standard for an MPhil.
Immediate fail: A very rare recommendation – you are given an immediate fail without the ability to resubmit and without entitlement to an MPhil.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

What Is the Pass Rate for Vivas?

Based on an analysis of 26,076 PhD students who took their viva exam between 2006 and 2017, the PhD viva pass rate in the UK is 96%; of those who passed, about 80% were required to make minor amendments to their thesis. The reason for this high pass rate is that supervisors will only put their students forward for a viva once they confidently believe they are ready for it. As a result, most candidates who sit a viva are already well-versed in their PhD topic before they even start preparing for the exam.

How Do I Arrange a Viva?

Your viva will be arranged either by the examiners or by the chairperson. The viva will be arranged at least one to two months after you have submitted your thesis and will arrange a viva date and venue that is suitable for all participants.

Can I Choose My Examiners?

At most universities, you and your supervisor will choose the internal and external examiners yourselves. This is because the examiners must have extensive knowledge of the thesis topic in order to be able to examine you and, as the author of the thesis in question, who else could better determine who they might be than you and your supervisor. The internal examiner is usually quite easy to find given they will be from your institution, but the external examiner may end up being your second or third preference depending on availability.

Can I Take Notes Into a Viva?

A viva is about testing your competence, not your memory. As such, you are allowed to take notes and other supporting material in with you. However, keep in mind that your examiners will not be overly impressed if you constantly have to refer to your notes to answer each question. Because of this, many students prefer to take an annotated copy of their thesis, with important points already highlighted and key chapters marked with post-it notes.

In addition to an annotated copy of a thesis, some students also take:

a list of questions they would like to ask the examiners,
notes that were created during their preparation,
a list of minor corrections they have already identified from their viva prep work.

How Do I Prepare for a PhD Viva?

There are several ways to prepare for a PhD viva, one of the most effective being a mock viva voce examination . This allows you to familiarise yourself with the type of viva questions you will be asked and identify any weak areas you need to improve. They also give you the opportunity to practise without the pressure, giving you more time to think about your answers which will help to make sure that you know your thesis inside out. However, a mock viva exam is just one of many methods available to you – some of the other viva preparation methods can be found on our “ How to Prepare for a PhD Viva ” page.

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Viva Voce Prep: 13 Essential Questions

What is your study about and why did you choose to research this in particular?
How did your research questions evolve during the research process?
How did you decide on which sources to include in your literature review?
How did you design your study and why did you take this approach?
How generalisable and valid are the findings?
What were the main shortcomings and limitations created by your research design?
How did your findings relate to the existing literature?
What were your key findings in relation to the research questions?
Were there any findings that surprised you?
What biases may exist in your research?
How can your findings be put into practice?
How has your research contributed to current thinking in the field?
If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

You will need to explain the impact of your literature review in the defense

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

You have to justify every choice in your dissertation defence

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

Need a helping hand?

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

Your dissertation defense needs to compare findings

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

What exactly were you asking in those questions, and what did your research uncover concerning them?
Which questions were well answered by your study and which ones were lacking?
Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

Discuss your contribution in your thesis defence

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future. This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree. So, you should take the time to make sure you can answer them well.

If you need assistance preparing for your dissertation defense or viva voce, get in touch with us to discuss 1-on-1 coaching. We can critically review your research and identify potential issues and responses, as well as undertake a mock oral defense to prepare you for the pressures and stresses on the day.

Defending your doctoral thesis: the PhD viva

Format for defending a doctoral thesis.

Every institution will have specific regulations for the thesis defence. In some countries or institutions, the convention is for thesis defences to be public events where you will give a lecture explaining your research, followed by a discussion with a panel of examiners (opponents). Both your examiners and the audience are able to ask questions.

In other countries, including the UK, the oral examination is usually conducted behind closed doors by at least two examiners, usually with at least one being from another institution (external examiner) and an expert in your topic of research. In the UK the supervisor does not participate in the viva, but may be allowed to observe. Sometimes someone from your own institution is appointed as an independent chair. Although it is now becoming more common for the candidate to have an opportunity to give a public lecture in UK institutions, this does not form part of the examination and may or may not be attended by the examiners.

Viva preparation

Take the preparation for your viva seriously and devote a substantial amount of time to it. The viva preparation checklist may be useful to help you prepare.

Your institution may offer courses on viva preparation and there may be opportunities to organise a practice viva. Take advantage of these opportunities: they can be extremely valuable experiences.

Things you may wish to take with you

your thesis – mildly annotated if you wish
a list of questions that you might be asked and your planned responses
any questions that you want to ask your examiners
additional notes which you have made during your revision
list of minor corrections that you have come across during your revision.

During the viva

Your study will have strengths and weaknesses: it is essential that you are prepared to discuss both. You could think of any weaknesses as an opportunity to demonstrate your skill at critical appraisal. Examiners will seek to find and discuss weaknesses in all theses. Do not interpret criticism as indication of a possible negative outcome.

Examiners have different personalities, styles and levels of experience. Sometimes a candidate may feel that a challenge is made in a confrontational way. Experienced, effective examiners will not be inappropriately confrontational, but some will. Do not take offence. A relaxed, thoughtful, and non-confrontational response from you will help re-balance the discussion. Having an independent chair can help maintain a constructive environment.

Useful tips for during your viva:

Ask for clarification of ambiguous questions or ask for the question to be repeated if necessary
Take time to think before answering
Be prepared to ask questions and enter into a dialogue with your examiners
Be prepared to discuss your research in context of other work done in your field
Be ready to admit if you don't know the answer to a question
Be prepared to express opinions of your own

You are not expected to have perfect recall of your thesis and everything that you have read and done. If you get flustered, or need to refer to notes your examiners will understand. They have been in your situation themselves!

After your viva

There are several possible outcomes of a thesis defence. Most commonly, your examiners will recommend to your institution that you are awarded your degree subject to minor corrections, although in some instances they might ask for more substantial work.

Types of PhD Viva Questions

Generally, examiners prepare a series of questions for you to answer at the PhD viva voce examination. These questions are primarily based on your thesis. However, the questions asked in PhD viva examinations can be broadly grouped under four basic headings:

General Questions
Research Context and Methods
Analysis and Findings
Discussions and Conclusion/Implications

Therefore, while preparing for your PhD viva and defending your thesis , you must consider the types of questions you’re likely to be asked. This helps in practicing your answers in advance and not being baffled during the viva. Practicing how you would answer questions based on these four basic categories will take you a long way in your preparations.

Commonly Asked PhD Viva Questions and How to Answer Them

While sticking to answering the most commonly asked questions might sound simple, it is equally important to be prepared for counter questions. Furthermore, it’s easy to go off on a tangent due to nervousness. This leads to opening up other lines of enquiry from the examiners in areas you hadn’t probably expected to be questioned about.

Ideally, you aren’t expected to dictate your thesis as it is. Examiners are interested in knowing your understanding of the research, its methods, analysis and findings, conclusion and implications, etc.

Despite the differences in every PhD viva, you must be prepared to answer these common questions logically. Below are some popular PhD viva questions to prepare:

1. Tell me about yourself.

Introduce yourself and talk about your areas of interest related to research. More importantly, focus on the areas you are extremely positive about. Briefly speak about your past achievements without overwhelming the examiners and sounding boastful. Keep the introduction professional.

2. What is the reason for selecting this research question?

The response to this question is often generalized by saying that you are interested in the topic. However, examiners want to hear the specifications of your interest in the topic. You must plan your answer stating the most interesting aspect of your research and why did you choose the research question over another topic from the same or allied domain. Furthermore, cite certain instances that helped you in selecting the research topic and the particular field for your project.

3. What is the key focus of your research?

Remember that the answer to this question is not about summarizing your research. It involves talking about the area of primary focus of research. Most importantly, in order to demonstrate the viability of your research, it is essential to identify some of the key questions it addresses.

4. Did the research process go as per your plan or were there any unexpected circumstances that you had to deal with?

The purpose of this question is not only to see whether you can work as per your structured plan, but also to understand your readiness with backup plans in case of unforeseen situations. An ideal way to answer this is by clearly stating if the project went as per your predefined plan. Furthermore, be honest in mentioning if you were assisted by others in dealing with it, as it may lead to a new set of questioning from the examiners.

5. After completion of your research, which part of the process did you enjoy the most and why?

Remember that the examiners know about a PhD student’s stressful journey . Therefore, do not elaborate on the hardships that you went through during your research, unless asked otherwise. Emphasize on the aspects of the research project that you enjoyed and looked forward to every time you stepped in your laboratory. Describe how you developed interest in newer approaches to conduct research.

6. As a researcher, what change has this research brought in you?

This question demands a strong, progressive, and positive response. Remember your first day in the research laboratory and compare it to today. Identify the differences in your traits as a researcher. Mention how following, reading, and analyzing other researchers’ works have brought a positive change in you. Furthermore, address how you overcame your shortcomings as a researcher and upskilled yourself.

7. Summarize your thesis.

Be well versed with the entire project. Start by explaining why you selected the topic of your thesis and close your explanation by providing an optimum solution to the problem. You must prepare for 3 types of answers for this question. Prepare a 1-minute, 3-5 minutes, and 10-minute summary and use the correct one based on your audience at the viva.

8. What developments have you witnessed in this field since you began your doctorate? How did these developments change your research context?

Familiarize yourself with the advances in your field throughout your PhD. Mention works of researchers you have referred to while working on your project. Additionally, elaborate on how other researchers’ work influenced your research and directed you to finding results.

9. What original contribution has your thesis made to this field of study?

Answer this question by keeping in mind what was known before in published literature and what you have added as part of being awarded your PhD. Firstly, you must present a major piece of new information during your research project. Secondly, elaborate on how your research expands the existing literature. Thirdly, mention how your work is different from other researchers’ works that you referred. Finally, discuss how you developed a new product or improved an existing one.

10. How well did the study design work?

While answering this question, you must focus on how your planned methods and methodologies were executed. Furthermore, mention how you tackled difficulties in study design and concluded your research.

11. Elaborate on your main findings and how do they relate to literature in your field?

While answering this question, elaborate on how you evaluated the key findings in your research. Mention the key factors involved and the reason for choosing a particular process of evaluation. Furthermore, explain how your findings are related with the literature review of your project. Mention its significant contributions in your field of research. In addition, discuss how your research findings connect with your hypothesis as well as the conclusion of your research.

12. What is the strength and weakness of your research?

While you may want to impress the examiner by emphasizing on the strengths of your research, being aware of the weaknesses and planning a directional move to overcome them is also equally important. Hence, mention the strengths first and elaborate on how they connect with the key findings. Additionally, underline the limitations and the factors that could be transformed into strengths in future research.

5 tips for passing your PhD viva

Every Doctoral researcher is expected to defend their thesis through an oral test - so discover how to prepare for your PhD viva and ensure you make a good impression on the examiners

What is a PhD viva?

A viva voce is an oral test, which literally translated means 'with the living voice'. It's a focused discussion giving you the opportunity to present your PhD thesis and then defend it in front of a panel of academic experts.

1. Understand what's expected of you

Traditionally, your thesis would always be discussed in person, with the interview style viva exam overseen by at least two (internal and external) examiners. Afterwards, they would provide you with a joint written report detailing any corrections that need to be made.

However, following the coronavirus (COVID-19) pandemic, the online PhD viva has become more commonplace with this examination more likely to take place via Microsoft Teams, Skype or Zoom.

The virtual experience will still typically follow the same format, but you'll be briefed in advance about the arrangements and any technical aspects to bear in mind. You can prepare for an online PhD viva by reading our video interview tips .

The chair of the viva is usually the internal examiner, although it can be an independent person. If you and the examiners agree, your PhD supervisor can also be present.

The examiners' main objective is to ascertain that you've written your own thesis, so if you have and are ready to talk through how you completed it, there's no need to panic. You may even enjoy the viva voce test.

In addition to assessing your thesis, the examiners are also there to assist you in deciding how and where this research might be published.

There are various results between a 'pass' and 'fail' but it's very rare to slip up at this point of a PhD. Most Doctorate awards will be made upon the condition that a number of minor corrections are made, with re-submission requests far less common.

However, while the pass rate is high, the viva exam itself can still be intellectually demanding. This is because you'll be debating issues that are conceptually complex, so preparation is crucial to your success.

At the end of it, whatever the outcome, be prepared to take on board any advice, as the examiners are there to help you improve your argument or the presentation of your thesis.

2. Know your thesis inside out

While you can be sure this isn't a memory test - as you're fine bringing notes and a copy of your thesis with you to the PhD viva - it's still important to gain a good understanding of what you've written and be knowledge about your field of study.

You'll need to think carefully about where this original piece of work would be placed in the context of the wider body of research carried out in this field. Questions will surely be asked about this, as well as whether the project could possibly be developed further through any future research.

As you'll be explaining parts of the document to the examiners (who'll also have a digital or physical copy), make sure the pagination is the same in your version as the one they're looking at to avoid any issues regarding everybody being on the same page.

If you get stuck at any point during the viva exam, you can use looking at the thesis as an excuse to re-focus and gather your thoughts.

3. Anticipate the viva questions

The examiners will have prepared a series of questions for you to answer at the viva voce, but this is nothing to get too concerned about. The questions will all be based on your thesis - what it's about, what you did and what you found out - and why this matters, in relation to your field of study.

So when getting ready for the viva, consider the types of questions you're likely to be asked, including:

What original contribution has your thesis made to this field of study?
Explain the main research questions you were hoping to address.
What are the strengths and weaknesses of your thesis?
If you had to start the thesis again, what would you do differently?
If funding was no object, describe how you'd follow on from this project.
What are your plans for the future?

It can be helpful to practise your answers beforehand, ideally vocalising them by arranging a mock mini viva - although, as you aren't restricted in terms of referring to notes in the exam, you can leave room for spontaneity, and you don't need to learn it all off by heart. If your viva is being held online, you can ensure any technical issues are identified before the day by having a run through with your supervisor or a friend.

While it may sound simple, stick to answering the questions posed. It's really easy to go off on a tangent and this can open up other lines of enquiry from the examiners - possibly in areas you hadn't expected to be quizzed about.

On the other hand, it's completely fine to bring personality to your reasoning and use stories as a means of describing the learning process you've gone through and the techniques mastered over the last three or four years that have brought you to this point.

4. Learn about your examiners' own work

The senior and well-respected academics who'll be reading your thesis will have their own ideas on conducting PhD standard research. Therefore, it's worth taking a look online at their academic profiles to discover if there's any correlation with the research they've had published and your own work.

From this, you should be able to gain a better idea of their motivations, their possible views on your thesis and the kinds of questions they might wish to discuss after having read through it.

You should research up-to-date theories, read any recent papers on the subject and speak to others who've recently had their own viva exam. Think about how your work differentiates from the research carried out by others in your chosen field.

Prepare to provide any supporting evidence asked of you by the examiners - for example, they may request to see experimental data you mention once the exam is over.

It's also necessary to check the policies and practices in place at your university and be sure of what the roles of the examiners are and how the viva panel will be structured. In many cases, Doctoral students can choose the examiners conducting the PhD viva.

5. Plan towards the viva exam

From the moment you know the date of your viva voce, work backwards and plan the steps you'll need to take before the day itself. Allow enough time to assess and review your work so that as the day approaches, you can focus on the practicalities.

This encompasses everything from making sure you relax, eat and sleep well the day before to arranging transport so you get to the viva on time - if you're attending in person.

An online PhD viva will present its own challenges, so ensure your working space is presentable and you still make an effort in terms of what you'll be wearing.

It's always advisable to adhere to interview etiquette and go with something that's both smart and comfortable. By looking the part, this should get you in the right frame of mind to communicate in a professional manner.

In the build-up, avoid any situations that might make you feel stressed and instead try to adopt a positive attitude, one that results in a genuine eagerness to engage in a debate about the work you've been toiling over for a substantial period of time.

If you're travelling to the examination, be sure to check that you have everything you wish to take with you, including the thesis, plus any notes or other materials that will help support your claims.

The PhD viva can last between one and four hours - usually two - so it's necessary to pace yourself to get off to the best possible start.

Remember, the examiners aren't trying to trip you up - they want you to pass and are primarily there to hear you talk about your project. So, after the polite introductions they'll typically start with an icebreaker to put you at ease and help calm the nerves.

It's meant to be an open and honest conversation about your work, so feel free to politely disagree with the examiners, especially on areas you feel strongly about. Don't forget to use examples from your thesis to back up what you're saying, remembering to be clear and concise.

If you know your way around your thesis and can explain your thinking and way of working, this test shouldn't be a problem. And if you don't know the answer to a specific question - admit it, as it's better to concede your limitations in an area than ramble on and hope they don't notice you're struggling to come up with an explanation. No research is perfect, so it's important to appreciate this during the discussion - but don't be too overcritical about your work either, as that's not your job.

Finally, as the PhD viva can quickly move from a series of friendly questions to those that are more in-depth, take some time to think before answering. Don't worry about any periods of silence from the examiners, as this certainly isn't an indication that you're doing badly.

Top 10 Ph.D. Viva Questions and How to Answer Them

Every doctoral candidate will complete the Ph.D. viva to defend a thesis and seek that coveted doctorate degree. You've worked hard throughout your academic career, and now you face this intimidating meeting! Before your viva, you might feel nervous, picturing yourself tap dancing as fast as you can in front of a firing squad. But your viva should feel more like a confident performance of your crowning research for an audience of adoring fans. Take a breath—you've done good work, and soon the committee will see that, too.

What is a Ph.D. viva? In this case, viva is short for viva voce, Latin for "living voice." The term refers to contexts in which responses to something are given out loud for people to hear, for example a real-time vote (all in favor, say "aye"!). In the academic context, the Ph.D. viva is a discussion between you (the Ph.D. candidate) and a panel of academic experts, during which you present your Ph.D. thesis. The panel of experts can include an internal and/or external examiner, your Ph.D. supervisor, and other people you can request to be in attendance, like your family members.

The examiner's main purpose is to determine that you've written your own thesis and ask you some probing questions about the work you've done. It's intended to be an open, frank conversation about your research, not an interrogation. Don't be afraid to challenge points your examiner makes if they don't align with what you've found in your study. Your expertise and passion about your work will demonstrate that you know your stuff and care deeply about it.

Of course, in order to think clearly and objectively about the subject you've been immersed in for months, you will need a healthy dose of confidence. To help you gain that confidence to make your viva a positive experience, preparation is key. Here are some prompts and questions you might be asked and how you can prepare beforehand to answer them.

1. Tell us about your study

Usually the first question is an opener and is asked with the goal of breaking the ice and getting you talking about your thesis. The items the panel presents to you will start broad and get more specific and involved as your viva progresses. Since you're here to talk about your project, give a good overview of who you are, your history in the field, and the process you followed in your study. You will have a lot of potential detail to provide, but since you won't know how much your panel is looking for, prepare synopses of different lengths: 1-minute, 3-minute, and 5-minute summaries.

2. What are your main research questions and why did you select them?

You'll very likely be prompted to talk about your research questions in detail, so be prepared to list the questions you set out to answer and the motivation behind selecting each one. Also, be prepared to discuss your aims, objectives, and hypotheses, just in case they ask about those as well.

3. What original contribution has your thesis made to this field of study?

Before you began your study, you probably looked at the gaps in the existing literature and decided on a research direction to fill those gaps. Now that you've finished your research, tell your panel what the world knows now as a result of your work. When future researchers delve into your subject matter, what will they cite you on?

4. Whose work has most influenced yours?

Because you went through the process of determining what your field of study still needs in terms of research and the kind of analysis that will contribute to it, you possess a pretty clear understanding of what has already been done. A lot of that knowledge comes from your academic journey leading up to the awarding of your doctorate, during which you've read a lot of papers and delved into the work that has been done before yours. Talk about the most influential works you've encountered. This can be a work that inspired you or papers that you felt were done poorly and motivated you to get it right. Bonus: The chair of the viva will be someone who knows a lot about your field, so take some time to get familiar with his or her work. Don't be a stalker, but be prepared to mention that you know what he or she has done. Not only will that demonstrate that you've prepared yourself for your presentation, but it will also show an interest in his or her life's work, which can't hurt. Don't spend too long on this, though—you're here primarily to talk about your work, not theirs.

5. What are the strengths and weaknesses of your thesis?

You certainly want to brag about your thesis and offer reasons why you and your work are great, so don't hold back about what went right. Start with the strengths; outline your main findings and give reasons why your study enabled you to uncover them. Then, while it might feel counterintuitive to point out the ways that your thesis isn't the greatest ever, a report about the weaknesses of your research shows a sense of self-awareness and humility that benefits your study in that it paves the way for future researchers and shows that you aren't blind to your own potential for growth. If you prepare your response to this question before your viva, you can craft your response to show that you have already thought about the ways you can address the weaknesses of your thesis.

6. What ethical considerations did you apply?

Most Ph.D. candidates encounter ethical issues during the course of their research, and the committee might want to know whether you took measures to ensure an ethical project. Did you follow any ethical protocols in gathering data? Did you provide informed consent to participants in your study? What are the ethical implications of your work?

7. Did your study go as expected? If you had to start the thesis again, what would you do differently?

Every researcher has at least some idea of what he or she might find upon performing a study. Many form research questions and perform the study to provide support for that expected outcome, but sometimes the research leads to a different result. Consider what your own expectations were before you began and the path your research process took, either in alignment with that expectation or not. Knowing what you know now, would you change anything about your research? Would you approach the process differently? Maybe you would forego a step or two knowing that it wasn't as consequential or helpful as you originally thought.

8. Now that you've completed your study, what did you enjoy about the process?

Ph.D. thesis examiners are looking for a candidate who is passionate about the work. Remember that they know exactly how stressful the process is, so avoid delving into the hardships you encountered. Instead, give a summary of the high points and the reasons you were excited to keep going. While you should keep the tone professional and avoid gushing, feel free to talk about your personal motivation for pursuing this study.

9. If funding was no object, how would you follow up on this project?

Every researcher faces limits regarding the scope of a study that prevent them from gathering as much data as they'd like. Time limits, budget caps, and lack of interest or willingness among study participants can all put a damper on the dreams a researcher has for an analysis. Money can solve most obstacles within an examination, so dream big—what could you make happen with an infinite budget? This is another question that reveals your passion for the subject.

10.What are your plans for the future?

Questions might not be limited to your thesis, so give some thought to where you will go from here. Describe your plans for your future research or professional pursuits; this gives the panel a sense of your passion for the work and sets you apart from a doctoral candidate who is just trying to check the boxes and get a diploma in hand.

The questions your panel asks you on the day of your viva will probably not be exactly the ones listed in this article, but these topics will almost certainly be covered during the discussion with your examiner. If you prepare responses to these questions and make sure you know your thesis inside and out, you will be much more ready to answer whatever the experts ask you. Equally important, planning out your responses will also help calm your nerves before this very important event, so give yourself the gift of preparation as you anticipate your Ph.D. viva. Good luck—you'll do great!

Take your thesis to new heights with our expert editing

Five top tips to pass your PhD viva

Research assistant Kirsty Devaney , who successfully completed her doctorate , provides five invaluable pieces of advice on passing the PhD viva.

First thing's first...what is the PhD viva?

Officially called the viva voce , meaning ‘living voice’ in Latin, the viva is an oral examination that sees a PhD student defend their thesis and showcase their knowledge to a panel of academic experts.

The viva takes place after you have completed your thesis and sees these experts ask you various questions to ensure you understand your work and have become an expert in your field.

Now, over to Kirsty…

1). Make your own learning space

"It's important on the lead up to the viva voce to have a space that's designated for your preparations. This could be at your university, in a coffee shop or at home.

"For instance, I took over my dining room table for a good two months. I had all of my resources there - my books, my thesis and lots of post-it notes."

2). Take some time away from your thesis

"I had a three-month wait in between submitting my thesis and sitting my viva, but I knew I couldn’t spend that time prepping as it would be far too intense. I took a full month off from revising and returned with a clear idea of what I needed to do."

3). Make a plan of action

"A month before my viva, I made a list of things I wanted to achieve before the day.

"One was to read through my thesis in full three times. I also committed to tabbing all of the important chapters, diagrams and data in my thesis, so I could refer to them quickly if needed.

"I then compiled a series of questions which I thought might come up in the viva and put them all into a pot. Once I’d got enough questions, I’d ask my husband to pull out one of the pieces of paper at random and ask me the question.

"Some days I would also catch up on any recent literature I may have missed that could be relevant.

"All of this proved incredibly useful for when my viva arrived."

4). Know your examiners

"When you’re close to completing your doctorate, you might have a conversation with your supervisors about the people in the field who might be external examiners.

"Once you know who they are going to be, it’s really important to get to know their research, what their research interests are and what methodologies they use."

5). Become the expert

"BCU does a mock viva, which I found incredibly helpful as it meant I could work on any difficulties I faced.

"One issue that arose from my mock was that I had to become a lot more confident and assertive about my research and my findings.

"When you walk into the room to do your viva, you are making the leap from being a student to having the certainty of an expert."

How scary was the PhD viva?

Kirsty, who also runs the successful Young Composers Project , says it’s important not to be too fearful of the examiners.

"They are there to challenge you, but they’re not trying to be mean for the sake of it,” she explains. “They want to make sure you know your stuff and haven’t just plagiarised the material.

"However, it’s important to breathe and take your time – they’re not expecting rapid-fire responses."

Kirsty credits the support of the School of Education and Social Work for getting her through her PhD.

"They really got it right,” she says. "They have been incredibly supportive. I never felt alone."

What is a PhD Viva Like? Sharing Graduates’ Experiences

When you’re trying to prepare for a PhD viva it can be really difficult to know what to expect. Unlike pretty much every other exam you’ll have experienced, the viva isn’t a standardised exam so you won’t find any past papers to practice on!

In this post I’ll be sharing the inside scoop on what a PhD viva is like. Both from my own experiences plus those of a few other PhD graduates.

Preparing for your viva? You may also want to take a look at some of the other PhD viva content I’ve written:

How to Defend a Thesis: An Introduction to the PhD Viva

Common phd viva questions.

Note: Every viva is different, in this post I’m focussing on my viva which took place in the UK. Two PhD graduates in Spain and the US also share their experiences.

What is a PhD viva?

For those who aren’t already familiar with what a PhD viva is, I’d highly recommend reading my full post on How to Defend a Thesis: An Introduction to the PhD Viva . This delves into how a PhD viva is assessed, who is present, the potential outcomes and what follows after.

As a quick recap, a PhD viva (also called a defense in some countries) is the final assessment a PhD student undertakes in order to pass their PhD. The format the viva can take varies from country to country and even institution to institution, but it typically involves discussing and defending your PhD thesis with experts in your field.

In this post you’ll hear about the viva experiences of three PhD graduates, each with a slightly different format.

To get the best understanding of how PhD vivas take place at your university I’d recommend:

Checking out any webpages your university have which formally outline the viva process
Speaking to your PhD supervisor
Chatting to colleagues such as postdocs who’ve been through it

Viva Experiences from PhD Grads

Prof elizabeth bondi-kelly , phd from harvard university, usa. assistant professor in computer science at university of michigan.

What was your PhD viva like? At my (virtual) defense, I had my committee, adviser, labmates, and family/friends. I was fortunate to give my job talk presentation again for my defense, so I had already had a lot of practice with presenting it and being asked questions about it.

How do you suggest people prepare for their PhD viva? For anyone who hasn’t had that opportunity, I highly recommend practicing to get a polished talk and practice answering questions about it.

Prof Raúl Santos-Rodríguez , PhD from Universidad Carlos III de Madrid, Spain. Full Professor in AI at University of Bristol.

What are PhD vivas like in Spain? The viva process in Spain varies from university to university. In most cases there are a few previous filters (internal/external reports) that make it such that, once you are through those, most of the pressure is off for the actual defence. The viva consists of a public presentation (usually with colleagues, friends and family in the audience) followed by questions from a panel, with each member asking their questions in turns. Both presentation and Q&A tend to be time limited (around 45 minutes each).

What was your PhD viva like? My viva experience was nerve-wracking but rewarding too. I remember how the exercise of putting together the presentation with the panel in mind actually gave me quite a different perspective on how to tell the story of my thesis. The event took place in a rather formal lecture room in our faculty. The panel consisted of five examiners (three externals including one from abroad, and two internals), all of whom were experts in my field of study. The panel asked me a wide range of questions, covering both very specific details and very high level matters. Once I answered their questions to their satisfaction, and after a short deliberation, I was given the good news. Overall, I found the viva to be a challenging but stimulating experience — and a good memory.

How do you suggest people prepare for their PhD viva? In terms of advice, I would suggest to:

Expect to be surprised by unexpected questions about your research
Be clear and concise, allowing examiners to ask for more details if needed
Practice your presentation without being constrained to say the same things every time
Not be afraid to ask for clarification if you don’t understand and take your time to respond
Enjoy the interaction with the examiners as they are experts that have a lot to add to your work

Portrait of PhD grad Prof Raul Santos-Rodriguez

Me! PhD from Imperial College London, UK. Research Fellow in AI at Bristol.

What was your PhD viva like? My viva, which took place over Microsoft Teams, included just an internal examiner, external examiner and myself. I gave a short presentation giving a summary of my PhD then about five hours were spent giving suggestions to improve content I was preparing to submit to journals. It was much less intimidating than I was expecting.

How do you suggest people prepare for their PhD viva? I mainly suggest to not over prepare! Sure, reread your thesis and swot up on any content you don’t feel comfortable describing (for instance certain techniques you’ve used), but I would caution against rehearsing too much: come to terms with the fact that you won’t be able to predict all the questions you’ll get asked.

I’ll be sharing more details on my viva experience in the rest of the post.

How To Prepare For a PhD Viva: The Advice I Was Given

Ahead of my own viva I typically got told to:

Relax and take your time in replying . This is somewhat sensible advice but a bit like telling someone to calm down: it doesn’t always work. Furthermore, relaxing can be hard to do when you also get told to…

Be prepared to answer questions about every part of your work . At face value this can seem reasonable: if you did the work, and deserve a PhD, you should be able to explain your work. Like many of us I heard the horror stories of examiners asking students to provide an explanation of fundamental techniques from first principles such as: “derive energy”!

However, I don’t think any rational examiner can expect a student to be able to answer every possible question about their PhD work. Not least because many students aren’t relaxed during the viva and instead are filled with nerves.

Thankfully, the reality is that examiners simply need to check that you’ve done the work and understand it. Therefore, yes you should be able to give a broad explanation of the techniques you’ve used but you can’t be expected to know everything about every technique.

Once it strays from your work to underlying principles I suggest that you explain as much as you feel comfortable then push back – the internal examiner (who acts as a moderator) should also step in if unreasonable questions are being asked. For more details on what PhD examiners are looking for, read this section of another post I’ve written .

How I Prepared for My PhD Viva

The time between submitting my thesis (14th February) and viva (25th March) was shorter than for most people. On top of that I didn’t spend long writing my thesis, meaning that the time between finishing my actual research and my viva was pretty short (around two months). Therefore I didn’t feel the need to “revise” for my viva. As in, sometimes you’ll hear of people reminding themselves of how certain experimental or analytic techniques work, but it was pretty fresh in my memory.

Instead, about 48 hours before my viva I started to read through my thesis. This is going to sound really bad but this was actually my first (and only) time properly reading through my thesis. No, I didn’t outsource or use ChatGPT to write my thesis!

When I submitted my thesis I had of course assembled all the chapters but had never given it a proper cohesive read all the way through. I read through the thesis over the course of 4-5 sittings. Reading fiction is definitely more fun .

I personally didn’t prepare by trying to come up with answers for lots of potential questions. But if you’re keen to have those to hand, read my Common PhD Viva Questions .

Why didn’t I prepare more?

I felt pretty relaxed about my viva. This isn’t because I am crazy clever or knowledgable. In fact, like many of us I’ve felt imposter syndrome, waiting for the moment that my lack of knowledge gets discovered: and if there ever a moment you’d expect this to happen it would be at your viva.

These three things relaxed me for the viva:

The external examiner seemed nice from the time I’d met him in the past at a conference. Certainly not a sure-fire sign that he wouldn’t turn into a scary beast during a viva but it seemed like a good starting point.
It was virtual. My viva took place right at the start of COVID and as such took place over Teams. For some reason this felt reassuring, as if I could get away with just unplugging my internet connection if they asked anything particularly scary. Thankfully I didn’t ever feel the need to try this out!
I had published PhD work in a well-ranked respected peer-reviewed journal. This was far and away the most reassuring thing. As mentioned in another post, examiners have to be confident in all of the following things to let you pass your PhD viva. If you have published some of your work somewhere respectable you tick many of the boxes immediately:

Oh, and I also didn’t prepare much because I was preoccupied with moving from London the week before my viva because of COVID and the start of lockdowns. Unexpectedly I ended up moving in with my girlfriend’s parents. It was rather chaotic but probably a useful distraction too.

My PhD Viva Experience

Who was at my viva.

Unlike vivas in other countries, such as the two international experiences shared above, a viva in the UK usually only involves:

PhD student – me in this case!
Internal examiner – an academic working in the same research area from the host university. They’re there to moderate the discussion and check that the university’s viva regulations are followed.
External examiner – another academic working in the research area from a different university. In my case this was someone who was a leader in the field who came from another UK university.

Optionally the PhD student may ask their supervisor to attend. I’ve known of a few people who’ve had their supervisor there too, though it’s pretty rare and unnecessary in my opinion.

How long did my PhD viva last?

All in all it was about five and a half hours.

This was much longer than I anticipated. When we scheduled the viva to start at 10am I naively expected us to be finished by lunch. Admittedly the examiners did suggest stopping for a break at lunch time but again I naively thought we’d be done shortly afterwards, so declined the opportunity for more than a 5 minute comfort break. In the end we finished up around 3:30pm.

How was my PhD viva structured?

Pie chart showing the four sections of my PhD viva: as described below

Introductions (2 minutes) . I’d actually never met my internal examiner (who should act as a moderator) so introductions were necessary.
Presentation (10 minutes) . A few weeks in advance of the viva I asked whether or not the examiners would like a presentation, and if so of what length. They said yes, 10-12 minutes. My supervisor strongly suggested making it on the shorter side: short and snappy is good and you’re about to have hours to discuss the details.
Discussion (5 hours, yes, really!) . More on this in a moment.
Decision and final comments (10 minutes) . I was asked to leave the metaphorical room (Teams call, remember!) and after a few minutes was invited back in after which they told me I’d passed with minor corrections. They gave a summary of the next steps, which were mostly administrative with paperwork, and briefly went over what changes/corrections they were expecting to the thesis.

What did we discuss for five hours?

Before my viva I had visions of it being like a job interview that lasts for hours and hours. They ask a slightly tough or awkward question, you try and answer, rinse and repeat x 100. The reality was really different.

The experience was much less intense than I was expecting. The examiners said from the outset that they were happy with the quality of the work and just aimed to give feedback to improve both the thesis and publications.

The vast majority of the viva was spent going page by page through the thesis covering points that the examiners had written down: not questions, merely suggestions. Very little of the viva involved me getting questioned: most of what I said was probably along the lines of “I agree, that’s a great idea”.

The examiners commented that they liked the [short] length of the thesis (140 pages before references) which may have helped. I was expecting at least a few dodgy questions such as explaining the content of a particular reference or deriving something from first principles. In all honestly I’m not sure I’d have been prepared for some of this, so was fine with not getting a hard time of it.

There were very few questions in general which was somewhat of a relief, though I was kind of looking forward to more of a discussion around the project. There were only two actual questions I think I got asked: one explaining why a particular technique wasn’t representative, and secondly a much more fluffy question of what would I do differently if I was starting again. That was it. I was really expecting more questions.

Every viva is unique so I can’t claim that my experience is representative but I will say that it was a relief to get through it unscathed.

What I wish I’d done differently

Asked more questions myself . The viva is one of the few times you’re likely to have hours of access to academic experts with such a keen interest in your work.

Was it tiring?

A little, just as any meeting which lasts over five hours would be. But because I didn’t feel like I was actually getting quizzed the whole time it was nowhere near as tiring as it could have been. Mostly I was tired just from having to pay attention for that long: I usually don’t sit still for more than 20 minutes!

What happened afterwards?

My viva was in March 2020, at the start of lockdown. I’d moved from London just the week prior and had to cancel the scheduled celebratory drinks with colleagues. So instead I had a glass of champagne with my girlfriend and her parents (who I was staying with).

Photo of me smiling with a glass of champagne after my viva

After that, I got cracking right away the next morning on making the examiners’ suggested changes to my thesis.

How to prepare your viva opening speech

A viva, or PhD thesis defence, typically starts with an opening speech by the PhD candidate. This opening speech can be prepared in advance. How? By following six simple steps that take you from checking university requirements, to structuring and practising your viva opening speech.

What is a viva opening speech?

Step 1: check the requirements for your viva opening speech, step 2: define the audience for your viva opening speech, step 3: develop key messages for your viva opening speech, step 4: structure your viva opening speech, step 5: create visual support for your viva opening speech, step 6: practice your viva opening speech.

Submitting a PhD thesis feels like a major milestone. And it is! But before being able to call themselves a ‘doctor’, most PhD students have to defend their thesis. And this thesis defence, or viva, tends to start with an opening speech.

A viva opening speech is a short presentation of the PhD thesis by the PhD candidate. It typically lasts between 10 and 30 minutes and kicks off the PhD defence during which the candidate has to answer questions from the examiners.

Questions from examiners are relatively unpredictable. A viva opening speech, however, can be prepared and practised in advance! Therefore, it constitutes a major part of getting reading for a PhD thesis defence.

Different universities have (sometimes vastly) different requirements for viva opening speeches. So, unfortunately, there is no one-size-fits-all advice.

Therefore, the first step to preparing a viva opening speech should always be to find out the specific regulations of your university.

Common factors to consider are the following:

The length of the viva opening speech. Whether you have to prepare a 10-minute or a 30-minutes presentation matters considerably.
The use of a (PowerPoint) presentation. Some universities require presentation slides. Others don’t. Make sure to follow all requirements or customary standards.
The focus of the speech. Some universities explicitly ask for a summary of the whole PhD thesis. Others may prefer several key findings, or arguments to kick off the discussion.
The target audience of the speech. Find out who you are supposed to address in your speech. More on this in Step 2!

Some information is easy to find. Some isn’t. Always talk to your PhD supervisor/s! PhD supervisors will know about the university requirements, can share their experiences and guide you in the right direction.

Once you are aware of your university’s regulation concerning viva opening speeches, it is smart to think a bit more about the target audience of your speech.

The target audience for your viva opening speech will influence the level of detail in your presentation, the complexity of the information, and the language and terminology you will use.

In the UK, for instance, the thesis defence usually involves only the examiners and the candidate. Thus, the viva opening speech will be directed at the examiners, who have all read the PhD thesis in advance and are experts in the candidate’s research field.

In contrast, in the Netherlands, for instance, PhD defences are public events. Viva opening speeches during these public events are used to share the focus of the thesis in simple language with the audience. The audience is usually family, friends and colleagues. Examiners are not even present during the speech.

Now it is time to brainstorm about the content of your viva opening speech! One harsh truth is that you simply cannot include everything. Summarising the work of 3, 4 or more years in a few minutes is incredibly challenging. You have to be selective. You have to summarise, abstract and prioritise.

The key messages for your viva opening speech should be in line with the nature of your PhD thesis. For those who have read your PhD thesis in advance, the content of your viva opening speech should not come as a surprise.

For instance, if you wrote a very theoretical PhD thesis, it makes no sense to focus your whole speech on your data collection and analysis. Instead, it makes more sense to emphasise the theoretical contributions of your PhD.

Next up, you should structure your viva opening speech: Breaking up the key messages into concrete parts helps you to develop a logic and convincing storyline.

Common ways to structure viva presentations are around the table of contents of the PhD thesis, around key findings, key arguments, or around case studies.

Finding the right structure for your opening speech is so important that I wrote a whole post on how to structure your viva presentation, including examples of different viva presentation structures .

As in every speech or presentation, visual support can be helpful. Therefore, if you are allowed to use PowerPoint slides or other forms of visual support for your viva opening speech, it is sensible to make use of this opportunity.

As with regular presentations, avoid too much text on slides. Instead, make strategic use of images, photographs, figures or diagrams to develop your storyline and bring your points across.

Finally, practice your viva opening speech! If your target audience is the thesis examiners, present your speech to your supervisor/s or fellow PhD students. Ask them for feedback and use it to improve your speech.

If the target audience is the general public, present to family members or friends outside of academia. Do they understand what you are talking about? Can they follow your storyline?

You should practice your viva opening speech up to the point that you can present freely, without reading from your notes. However, don’t learn the whole speech by heart. It is always noticeable if someone just recites text, and it will make you sound like a robot.

Lastly, when you practice make sure to keep a timer at hand. Most viva opening speeches have to adhere to a strict time limitation, and will simply be cut off if they exceed the given time. You don’t want this to happen on your big day! So make sure to practice sticking to your time.
