Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

How Hard is a PhD?

Amongst the general population, having a PhD is often seen as the pinnacle of academic achievements but how hard is it to achieve?

Having passed my PhD viva yesterday I now feel I’m in a position to really judge how difficult a PhD is!

Congratulations to Jeff @savvy_scientist who passed his PhD viva today, remotely! Now we're having a celebration – remotely! #StayHome pic.twitter.com/4rI0ZiCF5z — ImperialBiomechanics (@ICBiomechanics) March 25, 2020

A dive into the unknown

Any time we don’t have experience in something, the element of the unknown can make it hard to evaluate how hard it is.

Coming from your previous qualifications you may extrapolate and think that since your undergraduate degree was a step up from high school in work and difficulty, a PhD must be another step change in difficulty.

With PhDs it’s not helped by the fact that a lot of the time only the most academically capable students are interested in them, which may make you think you have to be really clever to do one. Plus, as they’re not that common it’s not always easy to find people with experience to speak to.

Growing up I didn’t know anyone who had done a PhD degree, heck none of my immediate family had been to university, so I appreciate that gaining an insight about PhDs isn’t available to everyone.

So how hard is a PhD?

The reality is that a PhD can be difficult, but mostly it’s just different .

How hard you might find certain aspects of a PhD really depend on your own working style and to a lesser extent personality. Let’s discuss the factors one by one.

How hard is it to manage the PhD workload?

During a PhD there will be times you have to stay late, or work weekends (every so often) but it’s nothing like undergraduate degrees, with relentless deadlines and all-nighters being a regular occurrence for a lot of us.

Something that studying for a PhD does have in common with undergrad is that there is always more work that you can get on with, which can be disconcerting. Though unlike undergrad this feeling doesn’t stop after exams where you can enjoy a long study-free summer, because there are no term times for a PhD. I’ve previously shared how much holiday I’ve taken as a PhD student .

You need to find a way to switch off, otherwise your mental health will suffer.

Prior to starting my PhD I worked as a research assistant for three years and I found it helpful to view my PhD as a full time job. Even all the way through to submitting my thesis, working consistently 9-5ish every day was enough. I do hear of people working every hour of the week but these are the exception rather than the norm.

For a deeper insight into my typical working schedule check out the post below where I shared my calendar.

How Much Work is a PhD?

PhD depth and breadth of study

If you’ve been in higher education for a while, you’ll have probably got used to learning a wide amount of topics in a short time. Topics are covered at a fast pace, sometimes in not much detail, without much time to build your understanding.

I can’t have been the only person who during undergrad was effectively have to fight fires, not having much time to concentrate and fully understand each topic before having to move on to the next one.

PhDs provide a step-change, where you focus in on a single topic to a much greater depth.

For most PhDs there will be a certain amount of knowledge you’re expected to have picked up from your previous degree(s), but the pace of a PhD is undoubtedly much more slow. The reality is that the breadth of a PhD topic is really quite limited, though it can often span several disciplines. It’s common for your project to involve topics you’re not completely comfortable with.

You have a lot of time to focus on just one topic and you’re expected and required to know the topic inside out. The good news is that you’re given more than adequate time to learn the ropes.

As a PhD student there is nothing wrong with refreshing your knowledge of basic topics, especially if it’s something you haven’t studied in years. I still look things up on YouTube and Wikipedia and there is no shame in doing so: you’re in this position to learn and produce scientific outputs, so it’s much better that you’re comfortable with the topic.

I would suggest that for most people a PhD is generally more relaxed than an undergraduate degree. That’s not to say there isn’t work involved, but the pace gives you breathing room to understand the topic comprehensively.

If there’s one key message I’d like to get across, it’s please don’t ever be scared to ask your supervisor questions. You’re not on your own.

That’s assuming your supervisor is interested in supervising, which sadly isn’t always the case. Lack of supervisor support is one of the main difficulties I’ve seen students face (in other research groups I should add!). I wrote some tips here for choosing projects and supervisors .

How to Choose a PhD Project & Supervisor

Essentially as long as you are willing to learn, I wouldn’t worry too much about this aspect of a PhD.

Is a PhD intellectually difficult?

You’ve probably heard the metaphor about standing on the shoulders of giants, and it’s true that as a PhD student you’re building on previous work carried out in the field.

However there usually isn’t an expectation to make massive intellectual strides forwards. In reality you’ll probably be giving a small nudge forwards to a small area of the field. For some people this can be a relief and make the idea of doing original research much more obtainable, whereas for others it may belittle the entire idea of doing research!

The reality of the situation is that PhD students may be seen as a cost effective source of labour to advance science. Although we’re often working on projects with complicated lofty descriptions such as “ nanoparticles impregnated with silver ions for cancer treatment ” or “ biphasic lubrication mechanics of soft engineering materials ” in reality the practical side of them does not require genius level intellect.

Oftentimes you’ll be doing pretty menial things behind these grand topic titles. These tasks require you to know what you’re doing, but rarely will you have devised the whole thing yourself.

Fun fact: at my first job after undergrad, working at one of the most prestigious universities in the world, my boss would sometimes bring in her gardener to pick up any slack, doing the same work as me and some of the post-docs.

A full house for @trayanovalab at the @ImperialBioeng annual lecture. Amazing work & images! #ComputationalCardiology pic.twitter.com/R2dxE7csbg — Jeff Clark (@savvy_scientist) June 18, 2018

Of course you need to be able to understand the concepts behind what you’re doing, but I wouldn’t worry too much if you’re worried that you have to be a genius to complete a PhD.

So is a PhD easy?

In terms of workload and difficulty a PhD isn’t necessarily as difficult as you might think, so don’t be scared off. That’s not to say it’s not without challenges which we’ll now go on to discuss.

How a PhD can be hard

Of course there are differences between projects, supervisors and universities but I’d say generally the main things which can make a PhD hard are:

Self motivation

Looking after yourself, dealing with isolation.

• Your ability to problem solve
• Fear of public speaking

Prior to studying for a PhD, your studies will likely have been structured by a timetable of contact hours, coursework deadlines and exams. Working towards a PhD is the first time you’re likely to experience fully independent working for extended periods of time. It will also involve work where no one, not even your supervisors, know all the answers. This can be daunting and I think this is where difficulties may stem from for many students.

A PhD is a long-term commitment so you need dedication to reach the end of a PhD.

By the end of your PhD you’ll have to demonstrate that you’ve contributed to your field with a thesis and/or peer-reviewed publications. This can be a challenge and without the regular undergraduate format of deadlines and exams, you may quickly lose focus. Regaining that focus and dedication is key to seeing your PhD through.

If this is something you struggle with check out my post on maintaining motivation during your PhD .

At Imperial we have two progress points throughout the PhD: one at 9-12 months (Early Stage Assessment) and another at 18-24 months (Late Stage Review). These formal progression checkpoints help by giving deadlines and a structure to work towards.

Solution: I believe one of the best ways to keep up productivity, and ensure you’re on the right track, is to meet regularly with the supervisor. I suggest meeting at least a few times per month. I do know some people who meet much less regularly and this can work for some people. However, I personally find myself chatting with my supervisor about far more than the types of things I’d want to ask in an email and this is where the mentorship aspect of a PhD can be made or broken.

In summary, working closely with your supervisor can make your PhD a lot less difficult.

It’s very easy to develop bad habits during your PhD such as:

• Eating badly and drinking too much coffee
• Getting stressed and working long hours
• Not getting exercise and sleeping poorly

From not cycling at all I've now cycled 1k+ miles in London, mostly commuting to @imperialcollege . Great way to get around with so many benefits. Started because of a free course by @RBKC & @Bikeworksuk w/ a refurbished bike! Few words about my experience: https://t.co/rGwSqomikD pic.twitter.com/joyVftxuVn — Jeff Clark (@savvy_scientist) August 30, 2019

Solution: Remember that working longer hours won’t necessarily help your productivity. Instead take time out of your day for breaks and go for walks. Dedicate time to look after yourself. If you’re looking for ways to stay efficient, think of doing things like commuting by walking or cycling. I’d also highly recommend cooking your own meals to stay healthy (and save money ).

When I say isolation I really mean a few different things:

Owning your own project

Every PhD project is different, you may collaborate with friends or colleagues for bits of your work but you are the only person driving forwards your project.

This means that you may face problems other people in the research group or department haven’t encountered. Not only could this be isolating but it may also set your project back if you don’t mitigate the risks.

Solution: Firstly, don’t be afraid to ask people for help. Maybe someone from your group doesn’t have the answer to your problems but they may offer useful advice or know someone else in the department who may help. Coffee breaks offer an opportunity to informally chat with colleagues, which can both be fruitful for your work and your mental health: here is a nice Science article about the positives of coffee breaks.

Imposter Syndrome

As every project is unique it can be very difficult to tell how you measure up to other people. At times you may struggle to understand what other people in your group are working on, but this doesn’t mean you’re not cut out for it! Supervisors have a good idea of what’s required for a project when you’re applying: if you’re accepted you’ll more than likely be fine in this regard.

Solution: Don’t compare yourself to others. This is fruitless, especially when every project is different anyway. Make sure you understand your own project well and you’ll be fine. Having a chat with other students can be a good way to reassure you that everyone goes through difficult times.

Staying social

If I asked you to close your eyes and picture a PhD student, what would you see? Personally I used to conjure up an image of a fatigued student wearing goggles and trapped in a lab, rarely seeing daylight.

That’s not always a hundred miles away from the truth, but it doesn’t have to be the case. We’ve already covered how working such long hours can be counterproductive, but also putting yourself in a solitary position like this can be both demoralising and awful for your mental wellbeing. Please don’t!

Solution: Take frequent breaks, get involved with activities your lab-mates or department are organising: or organise something yourself. Find something you enjoy and can look forward to going along to, you can still join clubs and societies as a postgrad. Being isolated can make a PhD so much more mentally difficult: it doesn’t need to be!

Solving problems

You hear people saying that to be a good researcher you have to be inquisitive and questioning everything. These are certainly good traits to have which can make the work more meaningful, but at the level of a PhD student I believe it’s much more important to work smart.

To me this includes the ability to:

• Think on your feet
• Don’t be afraid to ask your supervisor questions
• Be forward thinking and catch problems early

Solution: Set up a framework to overcome problems and always think of ways to mitigate risks by having a Plan B. For example I work with people who’ve waited six months for consumables to arrive: if you don’t consider risks like this you immediately set yourself up for a less productive and more stressful experience. As before, I really do recommend meeting with your supervisor frequently.

Public speaking

I’m not sure whether presenting your work is a requirement for every PhD but it’s certainly an expectation for most. If nothing else you’ll likely have to present in your viva.

A fear of public speaking is very common and as such it’s a common PhD difficulty to tackle.

It’s completely natural to be nervous with the idea of presenting, however that’s not a reason to avoid public speaking completely. On the contrary you’ll only get comfortable with it by practicing. We’re fortunate as researchers to get regular opportunities to try public speaking.

I certainly still get nervous myself but would rather face the fear than shy away from it: plus you feel great afterwards.

Solution: Take opportunities to give presentations, whether it be at lab meetings, departmental events or conferences. The great thing with being a PhD student is that you get to practice with no expectations that you’ll be perfect. It’s much better to face it now than push the problem back later in to your career. I’ve written some tips for how to keep your presentation interesting.

Presentation Skills for Students: How to Stay On Topic and Keep Audience Attention

Some example issues you might have to overcome as a PhD student

Common phd challenges.

Now that we’ve covered the categories of common PhD difficulties here are some common day to day challenges:

• You need to use a technique or piece of old lab equipment and there’s no one to teach you how to use it
• You’re scared to ask for help because you think you should already know the answer
• You’re not getting the results from an experiment you’re expecting to see
• You need to write a code to do something and have never coded before
• You’re struggling to understand a concept
• You’re bored of reading or are losing interest in the topic
• You feel lonely
• You’re stuck waiting for something to arrive
• You need to create nice looking diagrams
• You need to build a rig or piece of equipment from scratch
• You’re worried about giving a presentation
• Your supervisor isn’t providing support
• You’ve no idea what statistical analysis to use
• You’re facing funding limitations, meaning you can’t do all the experiments you ideally would
• You’re struggling to motivate yourself to write a 100+ page thesis!

I’ve written a separate post covering a range of challenges I faced during my own PhD and you can find that post here: Overcoming Academic Challenges and Failure During a PhD .

Overcoming PhD challenges

It’s normal to face problems during a PhD. It’s how you tackle these problems that will be the defining factor in how difficult you find the PhD.

Part of the joy in completing a PhD is knowing that you’ve managed to overcome these difficulties.

In all these scenarios having a chat with other people will help. Even if other students or staff can’t directly provide assistance, most people are very friendly and supportive which will boost your morale.

I can’t overstate how useful scheduling regular meetings with your supervisor is. It’s so much better to face problems early rather than awkwardly have to deal with it six months later. I meet with my primary supervisor every week and we work together to set short-term deadlines for my work which tie in with the larger targets.

For problems outside of your supervisor’s remit lots of universities provide additional support. For example the graduate school at Imperial lays on courses for PhD students covering how to code, using reference managers, statistics etc.

Plus there are usually facilities for dealing with things such as stress and anxiety via counselling, student support and chaplaincies. Don’t make the PhD more difficult than it needs to be, these facilities are put in place to help you.

Has my PhD been hard?

I’ve been surprised by how manageable the PhD has been. I wouldn’t say that any of the research work was particularly difficult, it has simply required dedication.

Good time management and taking my mental health seriously have helped a lot, as has considering it a full time job. Slow and steady wins the race. Simple steps like always having a backup plan to mitigate the chance of getting stuck if things go wrong has served me well.

I’ve never been a fan of presenting but have learned to expose myself to it in an effort for self improvement. Of the five conference presentations I gave during my PhD, I won prizes for two.

Remember that you may lack self confidence but how you come across to other people may not be how you perceive yourself: this can be very uplifting. If I can do it so can you!

Thesis-writing

I’m currently in the process of writing up a separate post dedicated to my experience of writing a thesis. In summary, for me personally, it wasn’t anything like as stressful as I was thinking it would be.

I gave myself approximately six weeks to write most of it. Mine was 190 pages in total which may sound daunting but I actually only had about 120 pages of proper content and it’s all with 1.5 line spacing. Each chapter was only about 20 pages which sounds much more manageable and really isn’t much for 3 years work!

Things which helped me included:

• Having already written up some results.
• Using figures I’d made for presentations.
• Not expecting it to be perfect.
• Setting myself tight deadlines. I gave myself two weeks to write the introduction, literature review and discussion chapters.

Some of us PhD students make things more difficult than they need to be, trying to make everything perfect. I’ve heard some staff say “good enough is good enough” which I’ve found a useful mantra.

I recommend not spending too long on the thesis because:

• Papers are what count, put your energy into them instead.
• There is no point trying to second-guess what your examiners may want to see, you could spend months deliberating and they’ll still potentially have corrections to suggest.

I was a bit nervous before my viva, which is normal. I was confident in the work I had done for the PhD, but was actually more concerned about being asked any theoretical or technical questions you’d be more likely to encounter in an undergraduate course.

Although it lasted more than five hours, mine was a supportive environment, mostly a discussion to give feedback to improve the thesis and publications. Remember to be honest and be reassured that you know your work better than anyone else.

In summary, how hard is a PhD?

• Most PhDs are not intellectually difficult but they do present other challenges
• How hard you may find a PhD depends on your ability to self motivate, look after yourself, deal with isolation, problem solve and master public speaking
• Everyone experiences challenges during their PhD but it’s how you confront those challenges that matters
• Make the most of your supervisor for support and guidance

10 Comments on “How Hard is a PhD?”

I have really been struggling on whether to apply for a PhD. This post has given me the realistic picture I needed. Thank you

Yay, I’m so pleased you found it useful, Ankita! If you can think of any other questions you’d like answered be sure to let me know. Best wishes

Thanks for sharing your experiences and insights, Jeff 🙂 I find this post really helpful in terms of being aware of what’s to come as I start my PhD journey – and more importantly, what I can do to overcome these potential obstacles!

Hey Julie, I’m pleased you’ve found it useful. Best of luck with your PhD!

Jeff, Thank you very much for putting this together. Im a second year PhD student who regularly finds themselves in crisis of confidence. This article really helps to give me a little perspective, empowering me to plough on regardless of nagging doubts!

Thanks very much for your comment, Callum. I’m really glad the article has helped. Best of luck with the rest of your project: you’ve got this!!

I am currently a full time MBA student who will graduate in December. My professor in Leadership actually approached me about whether I would consider becoming a higher ed professor and researcher. She noticed qualities in my writing and research that she said the job would suit me perfectly. I have been back and forth on the idea and your site has truly been a great boost for me in getting the confidence I need to apply for my PhD, so thank you :)!

Hey Sarah. Yay! I’m so glad the website has been useful for you, thanks so much for your comment. Do let me know if you have any other questions or suggestions for other content which would help. Best of luck with the end of your MBA and future PhD application! Best wishes, Jeff.

Jeff, Thank you for taking the time to put this together. I am entering my final term of my MS in Cybersecurity and graduate in May 21 and I was curious on the level of effort for a PhD. When my wife saw me looking at PhD programs however she lovingly made me close the browser so it may not be in the cards right now. Granted I do have 2 young children under 5, a full time job and am an Army Reservist so she isn’t wrong 🙂 However, I do really appreciate you putting this together to help other students interested in PhD programs. This has given me great insight into what to expect and what it will take. Thanks again! George

Hi George, Thanks so much for your kind comment, I’m glad it has been useful for you. In terms of how much effort a PhD is: anecdotally I did mine keeping pretty strictly to normal office hours of roughly 9-5 Monday-Friday and had the official letter confirming my PhD within 3.5 years of the day I started. Admittedly this is in the UK, I expect in the US it would take a little longer overall but the weekly workload doesn’t need to be overwhelming. I think my peers on average worked similar hours. The nice thing about research is that, assuming you have a reasonable supervisor, you are typically much more in control of your hours than in a traditional job. As long as you get the work done a good PhD supervisor doesn’t tend to care how you schedule your time so could fit quite nicely around other commitments such as childcare. Sometimes people think the flexible hours can only go badly for them: being expected to work longer hours than normal, but I don’t think this needs to be the case. Of course chucking endless hours at a task isn’t always useful, better to work smart! Sure some projects may involve intense sets of experiments but these are either usually few and far between or limited to fields like biology with cell experiments. In my experience anything based on a computer tends to be more flexible so you’re good. Basically the level of effort doesn’t need to be any more intense than a normal job. I hope this helps. Let me know if you have any other questions or I’d be happy to jump on a quick call if that’d help. Best of luck! Jeff.

Defending Your Dissertation: A Guide

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

PhD Thesis First Draft: 8 Practical Writing Tips for PhD Students

Many early career researchers will agree that the most difficult step in writing a PhD thesis is getting started. Students often find themselves mentally unprepared to take on this challenge as most formal training revolves around conducting research with little focus on how to write a PhD thesis. Uncertainty about the guidelines for PhD thesis writing and how to present their study in an engaging, impactful way often results in procrastination, self-doubt, and anxiety among otherwise confident researchers. The fact is students need to write a PhD thesis to complete their doctoral degree, and as ironic as it seems, the only remedy to this inertia is to meet this challenge head-on.

This article provides young researchers with practical tips to help them deliver a successful first draft when writing a PhD thesis.

• Create an outline and structure: A good way to start writing a PhD thesis is to first create a draft outline or structure of your thesis. Like journal articles, a PhD thesis must have an introduction that presents the key points of your study in a compelling way, a body section that contains the main aspects of your research along with supporting data and evidence, and a conclusion that summarizes the thesis and provides additional insights or suggestions for further research. This first step is important because once you have the right structure in place, summarizing your thesis can happen more easily.  
• Adhere to university or institutional guidelines: A common mistake that many students make while creating an outline and structure is not keeping in mind the guidelines for PhD thesis writing set by your university or institute. It’s important to adhere to the university or institute’s guidelines, for example the preferred structure or style of references, when writing a PhD thesis. Be sure to check with your supervisor to ensure that the word count, structure, citation style and other key elements of your thesis meet the recommended guidelines for PhD thesis writing.
• Use active voice and avoid grammatical and spelling errors: It is important to focus on using simple language that’s free of complicated jargon when writing a PhD thesis. To ensure better readability, use active voice instead of passive voice and avoid long winding sentences. Be aware of and avoid spelling and grammar errors such as dangling modifiers, subject-verb disagreement, and parallelism in your work. You can use AI tools like Paperpal for Word , which offers real-time suggestions to help you improve your language right from the first draft itself.
• Maintain consistency in your writing style: One of the most useful writing tips for PhD students is referring to the preferred style guide to ensure consistency in spellings, proper punctuation, correct hyphenation, and the right use of technical terms and phrases. Also check for consistency when it comes mentioning organizations and institutions, affiliations, references, legends and other key elements when writing a PhD thesis.
• Be careful when citing or quoting text: With the sheer quantum of research reading required when writing a PhD thesis, it can be difficult to keep track of sources of information. It is also quite possible for students to inadvertently introduce plagiarism in their writing by using chunks of well-written text as is or quoting information without citing it correctly. So be sure to properly cite any sources of data that you’re using in your thesis, including text, images and figures to avoid any ethical misconduct.
• Set a target deadline for completion : Another top writing tip for PhD students is to set a delivery date and stay committed to it. You can also share this goal with a broader set of people (peers, supervisor, friends, etc.), who will act as catalysts on the journey of writing your PhD thesis first draft and in the time you’ve set for yourself. It is critical however that the final deadline be realistic and take into account challenges that may come in the way of you achieving your goals.

Write your PhD thesis confidently with Paperpal’s AI writing assistant

• Take time to make revisions and proofread before submission: This is one of the most important writing tips for PhD students, but one that often takes the back seat. Remember that no matter how clear your first draft seems about your research findings, argumentation and flow, there will always be room for improvement and especially to your first draft. Once you’re done with your first draft, be sure to revisit each chapter and make the necessary edits before sharing it ahead with your mentor for feedback. When planning your work, make sure to factor in ample time for editing and proofreading, so that all the work you put into writing a PhD thesis is polished before submission.
• Remember it’s a first draft and not the final version: If you’re getting stuck with your writing, move on and start work on a different section; you don’t need to write in chronological order as long as you follow the structure you’ve created for yourself. Remember the cardinal rule when wondering how to write a PhD thesis – No one gets it right in the first draft itself. Capture your thoughts and findings as clearly and engagingly as possible in your first draft, don’t waste too much time striving for perfection at this stage. You can always fine-tune your writing and repeat this process as you go along, which can help you reach your writing goals faster.

Ten things I wish I'd known before starting my dissertation

The sun is shining but many students won't see the daylight. Because it's that time of year again – dissertation time.

Luckily for me, my D-Day (dissertation hand-in day) has already been and gone. But I remember it well.

The 10,000-word spiral-bound paper squatted on my desk in various forms of completion was my Allied forces; the history department in-tray was my Normandy. And when Eisenhower talked about a "great crusade toward which we have striven these many months", he was bang on.

I remember first encountering the Undergraduate Dissertation Handbook, feeling my heart sink at how long the massive file took to download, and began to think about possible (but in hindsight, wildly over-ambitious) topics. Here's what I've learned since, and wish I'd known back then…

1 ) If your dissertation supervisor isn't right, change. Mine was brilliant. If you don't feel like they're giving you the right advice, request to swap to someone else – providing it's early on and your reason is valid, your department shouldn't have a problem with it. In my experience, it doesn't matter too much whether they're an expert on your topic. What counts is whether they're approachable, reliable, reassuring, give detailed feedback and don't mind the odd panicked email. They are your lifeline and your best chance of success.

2 ) If you mention working on your dissertation to family, friends or near-strangers, they will ask you what it's about, and they will be expecting a more impressive answer than you can give. So prepare for looks of confusion and disappointment. People anticipate grandeur in history dissertation topics – war, genocide, the formation of modern society. They don't think much of researching an obscure piece of 1970s disability legislation. But they're not the ones marking it.

3 ) If they ask follow-up questions, they're probably just being polite.

4 ) Do not ask friends how much work they've done. You'll end up paranoid – or they will. Either way, you don't have time for it.

5 ) There will be one day during the process when you will freak out, doubt your entire thesis and decide to start again from scratch. You might even come up with a new question and start working on it, depending on how long the breakdown lasts. You will at some point run out of steam and collapse in an exhausted, tear-stained heap. But unless there are serious flaws in your work (unlikely) and your supervisor recommends starting again (highly unlikely), don't do it. It's just panic, it'll pass.

6 ) A lot of the work you do will not make it into your dissertation. The first few days in archives, I felt like everything I was unearthing was a gem, and when I sat down to write, it seemed as if it was all gold. But a brutal editing down to the word count has left much of that early material at the wayside.

7 ) You will print like you have never printed before. If you're using a university or library printer, it will start to affect your weekly budget in a big way. If you're printing from your room, "paper jam" will come to be the most dreaded two words in the English language.

8 ) Your dissertation will interfere with whatever else you have going on – a social life, sporting commitments, societies, other essay demands. Don't even try and give up biscuits for Lent, they'll basically become their own food group when you're too busy to cook and desperate for sugar.

9 ) Your time is not your own. Even if you're super-organised, plan your time down to the last hour and don't have a single moment of deadline panic, you'll still find that thoughts of your dissertation will creep up on you when you least expect it. You'll fall asleep thinking about it, dream about it and wake up thinking about. You'll feel guilty when you're not working on it, and mired in self-doubt when you are.

10 ) Finishing it will be one of the best things you've ever done. It's worth the hard work to know you've completed what's likely to be your biggest, most important, single piece of work. Be proud of it.

13 Tips to Prepare for Your PhD Dissertation Defense

How well do you know your project? Years of experiments, analysis of results, and tons of literature study, leads you to how well you know your research study. And, PhD dissertation defense is a finale to your PhD years. Often, researchers question how to excel at their thesis defense and spend countless hours on it. Days, weeks, months, and probably years of practice to complete your doctorate, needs to surpass the dissertation defense hurdle.

In this article, we will discuss details of how to excel at PhD dissertation defense and list down some interesting tips to prepare for your thesis defense.

Table of Contents

What Is Dissertation Defense?

Dissertation defense or Thesis defense is an opportunity to defend your research study amidst the academic professionals who will evaluate of your academic work. While a thesis defense can sometimes be like a cross-examination session, but in reality you need not fear the thesis defense process and be well prepared.

What are the expectations of committee members.

Choosing the dissertation committee is one of the most important decision for a research student. However, putting your dissertation committee becomes easier once you understand the expectations of committee members.

The basic function of your dissertation committee is to guide you through the process of proposing, writing, and revising your dissertation. Moreover, the committee members serve as mentors, giving constructive feedback on your writing and research, also guiding your revision efforts.

The dissertation committee is usually formed once the academic coursework is completed. Furthermore, by the time you begin your dissertation research, you get acquainted to the faculty members who will serve on your dissertation committee. Ultimately, who serves on your dissertation committee depends upon you.

Some universities allow an outside expert (a former professor or academic mentor) to serve on your committee. It is advisable to choose a faculty member who knows you and your research work.

How to Choose a Dissertation Committee Member?

• Avoid popular and eminent faculty member
• Choose the one you know very well and can approach whenever you need them
• A faculty member whom you can learn from is apt.
• Members of the committee can be your future mentors, co-authors, and research collaborators. Choose them keeping your future in mind.

How to Prepare for Dissertation Defense?

1. Start Your Preparations Early

Thesis defense is not a 3 or 6 months’ exercise. Don’t wait until you have completed all your research objectives. Start your preparation well in advance, and make sure you know all the intricacies of your thesis and reasons to all the research experiments you conducted.

2. Attend Presentations by Other Candidates

Look out for open dissertation presentations at your university. In fact, you can attend open dissertation presentations at other universities too. Firstly, this will help you realize how thesis defense is not a scary process. Secondly, you will get the tricks and hacks on how other researchers are defending their thesis. Finally, you will understand why dissertation defense is necessary for the university, as well as the scientific community.

3. Take Enough Time to Prepare the Slides

Dissertation defense process harder than submitting your thesis well before the deadline. Ideally, you could start preparing the slides after finalizing your thesis. Spend more time in preparing the slides. Make sure you got the right data on the slides and rephrase your inferences, to create a logical flow to your presentation.

4. Structure the Presentation

Do not be haphazard in designing your presentation. Take time to create a good structured presentation. Furthermore, create high-quality slides which impresses the committee members. Make slides that hold your audience’s attention. Keep the presentation thorough and accurate, and use smart art to create better slides.

5. Practice Breathing Techniques

Watch a few TED talk videos and you will notice that speakers and orators are very fluent at their speech. In fact, you will not notice them taking a breath or falling short of breath. The only reason behind such effortless oratory skill is practice — practice in breathing technique.

Moreover, every speaker knows how to control their breath. Long and steady breaths are crucial. Pay attention to your breathing and slow it down. All you need I some practice prior to this moment.

6. Create an Impactful Introduction

The audience expects a lot from you. So your opening statement should enthrall the audience. Furthermore, your thesis should create an impact on the members; they should be thrilled by your thesis and the way you expose it.

The introduction answers most important questions, and most important of all “Is this presentation worth the time?” Therefore, it is important to make a good first impression , because the first few minutes sets the tone for your entire presentation.

7. Maintain Your Own List of Questions

While preparing for the presentation, make a note of all the questions that you ask yourself. Try to approach all the questions from a reader’s point of view. You could pretend like you do not know the topic and think of questions that could help you know the topic much better.

The list of questions will prepare you for the questions the members may pose while trying to understand your research. Attending other candidates’ open discussion will also help you assume the dissertation defense questions.

8. Practice Speech and Body Language

After successfully preparing your slides and practicing, you could start focusing on how you look while presenting your thesis. This exercise is not for your appearance but to know your body language and relax if need be.

Pay attention to your body language. Stand with your back straight, but relax your shoulders. The correct posture will give you the feel of self-confidence. So, observe yourself in the mirror and pay attention to movements you make.

9. Give Mock Presentation

Giving a trial defense in advance is a good practice. The most important factor for the mock defense is its similarity to your real defense, so that you get the experience that prepares for the actual defense.

10. Learn How to Handle Mistakes

Everyone makes mistakes. However, it is important to carry on. Do not let the mistakes affect your thesis defense. Take a deep breath and move on to the next point.

11. Do Not Run Through the Presentation

If you are nervous, you would want to end the presentation as soon as possible. However, this situation will give rise to anxiety and you will speak too fast, skipping the essential details. Eventually, creating a fiasco of your dissertation defense .

12. Get Plenty of Rest

Out of the dissertation defense preparation points, this one is extremely important. Obviously, sleeping a day before your big event is hard, but you have to focus and go to bed early, with the clear intentions of getting the rest you deserve.

13. Visualize Yourself Defending Your Thesis

This simple exercise creates an immense impact on your self-confidence. All you have to do is visualize yourself giving a successful presentation each evening before going to sleep. Everyday till the day of your thesis defense, see yourself standing in front of the audience and going from one point to another.

This exercise takes a lot of commitment and persistence, but the results in the end are worth it. Visualization makes you see yourself doing the scary thing of defending your thesis.

If you have taken all these points into consideration, you are ready for your big day. You have worked relentlessly for your PhD degree , and you will definitely give your best in this final step.

What should universities' stance be on AI tools in research and academic writing?

• How Long Is a PhD Thesis?
• Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

• University of Edinburgh: 100,000
• University of Exeter: 100,000
• University of Leister: 80,000
• University of Bath: 80,000
• University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

• Arts & Humanities: 75,000
• Medicine, Dentistry & Health: 75,000
• Science: 80,000
• Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

• Average number of pages = 204
• Median number of pages = 198
• Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

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

How difficult is it to get a PhD? The real doctorate struggles.

There is no doubt that getting a PhD is no small feat. It requires dedication, hard work, and plenty of motivation to stay on track.

Getting a PhD can be a very challenging process that requires several years of intensive research, coursework, and writing. However, the difficulty of obtaining a PhD can vary depending on factors such as the specific program and field of study.

Also, I have witnessed that the individual student’s background and preparation, and the level of commitment and effort they are willing to invest also highly influence how hard a PhD is for an individual candidate.

In order to complete in a timely fashion PhD candidates must also be prepared to invest a significant amount of time into their studies in order to complete the necessary coursework (US-based PhDs) and research.

The process can be especially difficult if the student is attempting to balance work or family life while completing their studies.

Quite often younger PhD students find it easier than mature age students due to the fact that they have fewer adult commitments and responsibilities in their private life – but this isn’t always the case.

However, with proper planning and perseverance, it is certainly possible for anyone to reach this educational achievement.

It was something I was very proud to have completed and it certainly opened doors to other opportunities.

Why is a PhD so difficult?

A PhD is an advanced academic degree that requires a huge amount of dedication and hard work.

Ask any PhD graduate and they are likely to say that it is one of the most challenging parts of their life in academia.

That is because it is a lengthy process that involves several years of research, writing, and, at the end, defending a dissertation in front of other experts in the field in order to be awarded the degree.

Typically, a PhD student will:

• have completed a Masters degree to a high standard for acceptance into the PhD program
• conduct a literature review of a field to find research gaps
• generate a research question and hypothesis
• work over multiple years to explore their research question and answer it fully
• fail multiple times and have their work critiqued continuously by experts in their field and that PhD supervisor.
• Write up their work in peer-reviewed journals and their thesis
• defend their peer-reviewed papers and their thesis
• continually stay up-to-date with the literature throughout their entire course
• some students may also have teaching and other administrative requirements at the University in which they are studying.

The entire process can be quite challenging and overwhelming, as students must stay up-to-date with new developments in their area of study while also meeting stringent academic standards.

They must also be able to effectively communicate complex concepts to their peers in things like peer-reviewed papers as well as at conferences and symposia.

All these factors make obtaining a PhD an incredibly difficult task but one that is ultimately rewarding for those who are successful.

It can be confronting when you look at a PhD in one whole chunk. However, by splitting down the tasks involved in a PhD it can become much more manageable and less detrimental on your mental health.

• Is a PhD worth it now in 2023? [the data]  

What is the hardest part of getting a PhD?

One of the most challenging aspects of obtaining a PhD is that it takes a great deal of time and dedication.

You shouldn’t underestimate how easily your brain plays tricks on you over a multi-year project. Staying on course and ignoring your internal monologue is one of the most challenging parts again a PhD.

It can take anywhere from five to seven years of rigorous study and research to complete all the requirements for a PhD.

During this time, students must master complex topics in their field, conduct independent research projects, write lengthy dissertation papers, and navigate any number of other challenges along the way.

Working with your supervisor

Working with your PhD supervisor can, for some, be one of the most difficult aspects of doing a PhD.

Your PhD supervisor will dictate the outcome of your PhD and therefore it is worth spending a lot of time making sure you select the right PhD supervisor for you.

Some supervisors want to completely micromanage whilst others are happy to allow their students to explore freely.

Taking the time to make sure you can fully nurture this relationship will also ensure a less stressful PhD.

If you want to know more about great ways to build a relationship with your supervisor check out my YouTube video:

I also have a lot of content on my YouTube channel on choosing and working with academic supervisors.

Is it worth getting a PhD?

Whether or not it is worth getting a PhD depends on a few different factors.

For some people, having a PhD is important for career advancement and provides an opportunity to pursue higher-level positions in their field.

It may also be beneficial for those that wish to teach at the university level or conduct research in their field of interest.

On the other hand, pursuing a PhD can be time consuming and expensive, and the long years of study may not ultimately result in any tangible rewards.

I also have a YouTube video where I talk about whether getting a PhD is worth the effort:

There are a load of juicy secrets in this one.

Whether or not it is worth getting a PhD will depend on the individual’s goals and objectives. If they are looking for career advancement opportunities or want to pursue teaching or research opportunities, then getting a PhD may be worth the cost and effort involved.

How hard is it to manage the PhD workload?

You may have heard that a PhD is a massive task because of the workload.

If you are doing your PhD in the United States of America you may find that there are three years of coursework to complete before you start the research component of the degree. This workload can be huge.

No matter where you do your PhD the amount of work and effort it takes to complete a PhD is much greater than what was required for an undergraduate degree.

No longer do you have set deadlines and a structured course – you will need to figure out the pathway through your PhD on your own.

Furthermore, given that most U.S.-based PhD programs are structured like traditional college courses, it can be difficult to stay on top of all the readings and material without falling behind.

If you decide to pursue a doctoral degree you must make sure you are prepared for the increased workload and dedication required in order to be successful.

Speak to your support networks and your family to ensure that they will be able to support you when things get tough.

Is a PhD intellectually difficult?

You may be surprised to hear that PhD isn’t necessarily intellectually difficult. But it does require dedication and effort to work through some challenging intellectual problems.

I often say that a PhD is 80% dedication, 10% smarts and 10% luck.

A PhD can be an extremely intellectually challenging experience for any student because it requires a great deal of dedication and hard work to complete, and it is regarded as the highest level of education available.

The expectations of a PhD student are far greater than those of an undergraduate, and the research process can take years to complete.

Nonetheless, it is your ability to persevere through problems and stick to your research plan by improving on your research little by little day after day that will really dictate how successful your PhD is.

I have seen incredibly smart people fail a PhD whilst others, who have not done so well in undergraduate, have flourished in the research environment.

How long are PhD programs?

Research shows that the average amount of time to complete a PhD across disciplines is 4.4 years. Depending on the country, a PhD will take anywhere between two and seven years to complete depending on whether there is a coursework component (US universities).

The majority of students taking anywhere from five to seven years to complete their degree.

This is due to the nature of PhD programs, which require significant research and fieldwork experience in addition to coursework.

Depending on a student’s chosen field of study, some PhD programs may last longer than others.

Here is data from a study that looks at Australian university PhD completion  published in 1994 .

Some PhD programs may have requirements that must be met before graduation, such as publishing research or completing an internship. It is important for prospective students to understand what is expected of them in order to ensure they will be able to complete their program within the allotted timeframe.

How many hours do PhD students work?

Although PhD students often have to put in long hours of work to complete their degree is not necessary that a student puts in an insane number of hours as long as they were continuously and diligently towards the end goal of getting a PhD.

The amount of hours that a PhD student work will depend on the culture of the labs that they are currently researching in.

Some supervisors require students to be in the lab for many hours every day whilst others are happy from a 9-to-5 “work schedule”.

On average, PhD students work around 40-50 hours per week.

This includes time spent in:

• independent study
• researching
• and much more

Researching and writing a dissertation can require even more hours of work.

In addition to this, many PhD students also teach classes or take on other roles within the university that add to their workload.

All of this means that PhD students can often find themselves putting in long hours and having little free time outside of the academic demands of their program.

Wrapping up

This article has been through all of the difficult components that people may face if they decide to get a PhD.

I was able to complete my PhD in three years and I somewhat enjoyed the process. Of course it had its challenges but overall it was a worthwhile and rewarding experience for me.

However, some people’s experiences are also very different due to different pressures outside of academia and the culture in the research group in which they are working.

The ultimate difficulty depends very much on the individual circumstances and dedication of the PhD student but always involves dedicating yourself to the pursuit of knowledge over many years. This, in itself, can be a very challenging aspect to overcome.
