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

• 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

• PhD Viva Voces – A Complete Guide
• Doing a PhD
• A PhD viva involves defending your thesis in an oral examination with at least two examiners.
• The aim of a PhD viva is to confirm that the work is your own , that you have a deep understanding of your project and, overall, that you are a competent researcher .
• There are no standard durations, but they usually range from one to three hours, with most lasting approximately two hours .
• There are six outcomes of a PhD viva: (1) pass without corrections (2) pass subject to minor corrections, (3) pass subject to major corrections, (4) downgrade to MPhil with no amendments, (5) downgrade to MPhil subject to amendments, (6) immediate fail.
• Almost all students who sit their viva pass it, with the most common outcome being ‘(2) – pass subject to minor corrections’.

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.

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."

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.

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.

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

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 .

Preparing for your own viva? I’ve created a set of viva preparation worksheets which are available for free in the resource library. Click the image below for access!

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?

• 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).

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

How to structure your viva presentation (with examples)

Most PhD vivas and PhD defences start with a short presentation by the candidate. The structure of these presentations is very important! There are several factors and approaches to consider when developing your viva presentation structure.

Factors to consider when developing a viva presentation structure

Structuring your viva presentation traditionally, structuring your viva presentation around key findings, structuring your viva presentation around key arguments, structuring your viva presentation around case studies, final thoughts on viva presentation structures.

A PhD viva or PhD defence is often one of the last steps that PhD students have to pass before receiving a doctorate. The viva or defence usually starts with a short presentation of the PhD candidate on the PhD thesis.

Presenting a whole PhD in a short amount of time is very challenging. After all, a PhD is often the result of several years of work!

It is simply impossible to include everything in a viva presentation.

Therefore, tough choices have to be made in terms of what to include, what to highlight, and what to exclude.

The structure of a viva presentation plays a crucial role in bringing across the key messages of your PhD.

Therefore, there are several factors to consider when developing a viva presentation structure:

• Available presentation time : Viva presentations usually last between 10 and 20 minutes, but every university has different regulations. Developing a structure for a viva presentation that lasts 10 minutes is different from developing one for a presentation that lasts 20 minutes or more. Thus, find out how much time you are allowed to present!
• The key contribution of your thesis: The structure of a viva presentation should reflect the content and key messages of the PhD thesis. For instance, if you have written a very theoretical PhD thesis, it makes no sense to structure your whole presentation around your data collection and analysis. Make sure that the viva presentation structure is in line with your main messages.
• University standards: It is recommended to discuss your ideas and plans for your viva presentation structure with others, as each university may have may be different (and even unspoken) rules and standards. Ask your supervisors about their preferred viva presentation structure. And talk to your peers who defend their theses before you.
• Clear storyline : Every presentation should have a logical structure which allows the audience to follow a crystal-clear storyline. This is also true for viva presentations. Thus, clarify your storyline and develop a presentation structure that supports it.

A very traditional viva presentation structure simply follows the structure of the PhD thesis.

This means that the viva presentation covers all parts of the thesis, including an introduction, the literature review, the methodology, results, conclusions, etcetera.

The advantage of this rather traditional format is that it provides information on each thesis chapter. Furthermore, it is relatively easy to prepare.

The disadvantage of this traditional format is that it is very challenging to fit all the information in a – let’s say – 10-minute presentation.

Furthermore, it can result in a presentation that is quite boring for the examiners, who have read the thesis in preparation for the viva.

One interesting way is to structure a viva presentation around the key findings of the PhD research.

For instance, you can select your three main findings which you each connect to the existing literature, your unique research approach and your (new) empirical insights.

A viva presentation structure around key findings emphasises the unique contribution of a PhD thesis, particularly in empirical terms.

A challenge of this structure, however, is to narrow down the presentation to a handful of key findings.

Furthermore, it might be tricky to find enough time during the presentation to discuss your theoretical framework and embed your discussion in the existing literature when addressing complex issues.

A viva presentation structured around key arguments is very similar to one that is structured around key findings. However, while key findings place more emphasis on the empirical data, key arguments operate at a higher level:

Arguments are sets of reasons supporting an idea, which – in academia – often integrate theoretical and empirical insights.

So, for example, your key argument 1 is your stance on an issue, combining your theoretical and empirical understanding of it. You use the existing theory to understand your empirical data, and your empirical data analysis to develop your theoretical understanding.

A viva presentation structure around key arguments is probably the most difficult viva presentation structure to choose.

However, if it is well done, it is probably the most academically strong and advanced way of defending your PhD.

Another common way to structure a viva presentation is around case studies or study contexts.

This structure is only applicable when the PhD thesis includes a comparative (case study) analysis, which is quite common in the social sciences and humanities.

A presentation can, for instance, first discuss the theoretical framework and research approach, then present Case 1, and then Case 2 or more if applicable.

A viva presentation structure around case studies can be easy to follow for the audience, and shed light on the similarities and differences of cases.

However, as always, you need to reflect on whether the structure supports your key message. If your key message does not centre around similarities and/or differences in cases, this is not the structure for you!

Every PhD thesis is unique, and therefore also every viva presentation structure should be unique.

The key to a good viva presentation is to choose a structure which reflects the key points of your PhD thesis that you want to convey to the examiners.

The example viva presentation structures discussed here intend to showcase variety and possibilities and to provide inspiration.

Never just copy a viva presentation structure that worked for others .

Always think about what fits best to your thesis, asking yourself the following questions:

• What is the main message of my PhD that I want to share during my viva?
• How do I develop a crystal clear storyline to bring this main message across?
• How can I structure my viva presentation to support and facilitate this storyline?

Spurring Action Against Cervical Cancer

Prajakta Adsul, PhD, from UNM Cancer Center attended the White House Cervical Cancer Forum focused on education, prevention, early detection and treatment

During the last days of January, which is Cervical Cancer Awareness month, Prajakta Adsul, MBBS, PhD, MPH, headed for Washington, D.C. Adsul had been invited to participate in the Inaugural White House Cervical Cancer Forum hosted by the Office of Science and Technology Policy, through the Biden Moonshoot Initiative.

Adsul is a global leader in cervical cancer prevention and implementation research. She and her team conducted the largest study of cervical screening among LGBTQIA+ individuals in the United States, and they published their research results last year in Frontiers in Oncology. The team continues to evaluate the study data with several publications planned.

The Forum at the White House began with a public session in which survivors and advocates for cervical cancer shared their experiences.

Thus grounded in priorities, the forum attendees heard remarks from Kimryn Rathmell, Director of the National Cancer Institute, and Danielle Carnival, PhD, Deputy Assistant to the President for the Cancer Moonshot.

Carnival told the attendees, “We are here today united by a commons mission … to get us on a path to virtually eliminate this disease which, today, impacts more than 600,000 people around the globe each year.”

The Forum ended with several sessions aimed at generating new ideas, actions and collaborations to combat cervical cancer worldwide.

In New Mexico, 100 women are expected to receive a diagnosis of cervical cancer in 2024, according to American Cancer Society estimates. The vast majority of cervical cancers — 91% — are caused by Human Papillomaviruses (HPVs). Three vaccines have been approved in the US for use against HPV.

Prajakta Adsul, MBBS, PhD, MPH

Prajakta Adsul, MBBS, PhD, MPH, is an Assistant Professor in the UNM Department of Internal Medicine, Division of Epidemiology, Biostatistics, and Preventive Medicine and is a full member of the Cancer Control and Population Sciences research group at the UNM Comprehensive Cancer Center. A primary care physician by training, Dr. Adsul received her doctorate in Public Health and more recently completed a Cancer Prevention Fellowship with the Implementation Science team at the National Cancer Institute.

UNM Comprehensive Cancer Center

The University of New Mexico Comprehensive Cancer Center is the Official Cancer Center of New Mexico and the only National Cancer Institute-designated Cancer Center in a 500-mile radius.

Its more than 120 board-certified oncology specialty physicians include cancer surgeons in every specialty (abdominal, thoracic, bone and soft tissue, neurosurgery, genitourinary, gynecology, and head and neck cancers), adult and pediatric hematologists/medical oncologists, gynecologic oncologists, and radiation oncologists. They, along with more than 600 other cancer healthcare professionals (nurses, pharmacists, nutritionists, navigators, psychologists and social workers), provide treatment to 65% of New Mexico's cancer patients from all across the state and partner with community health systems statewide to provide cancer care closer to home. They treated approximately 14,000 patients in about 100,000 ambulatory clinic visits in addition to in-patient hospitalizations at UNM Hospital.

A total of nearly 400 patients participated in cancer clinical trials testing new cancer treatments that include tests of novel cancer prevention strategies and cancer genome sequencing.

The more than 100 cancer research scientists affiliated with the UNMCCC were awarded $35.7 million in federal and private grants and contracts for cancer research projects. Since 2015, they have published nearly 1000 manuscripts, and promoting economic development, they filed 136 new patents and launched 10 new biotechnology start-up companies.

Finally, the physicians, scientists and staff have provided education and training experiences to more than 500 high school, undergraduate, graduate, and postdoctoral fellowship students in cancer research and cancer health care delivery.
