Your PhD will last several years, and your supervisor will likely have a big impact on your experience (although in some programmes you may be required to rotate between different advisors or labs). We think the quality of your relationship with your supervisor, their availability, skills and alignment with your goals can make a significant difference to your own development and the trajectory of your career, especially if you stay in research.
Not all students will need to identify a supervisor before beginning a PhD. For example, in America it’s common to be allowed a year or two in a PhD programme before identifying a research question and supervisor. This advice applies primarily to students who need to find a supervisor as part of the application process, although we suggest all students check that there are some supervisors on the programmes they apply to who they would like to work with.
We think it’s valuable to seek out additional advice tailored to your specific situation. Here are some ways to get more advice:
Here are some ideas of how to find potential supervisors:
Consider keeping a spreadsheet of the programmes and supervisors you’re interested in, listing factors such as location, research fit and funding that you want to take into account. It will also help you follow up 1-2 weeks later if you have a record of who you contacted.
Universities will have different policies on who can supervise PhDs. If you find someone during your search who seems like a great fit but can’t be a primary supervisor, they may be willing to be your secondary supervisor or mentor.
Check as soon as possible whether a supervisor you’re interested in is accepting students during the upcoming application cycle before investing more effort in learning about them or the relevant university or lab.
The following are some factors we suggest keeping in mind when deciding which supervisors might be a good fit for you.
While it is helpful to have a supervisor who has a good understanding of the topic/concept you want to study, having a supervisor (or research group) with strong expertise in a methodology you want to master may be more important to your development, as long as they are receptive to your topic.
This is something you can try to gauge by talking to the supervisor and their students. If an academic is earlier in their career, their career progression will depend on supervising students, so it's likely they will be more hands-on, while later-career academics often give more autonomy, but this is only a general rule.
If you’re in a collaborative environment, a lot of value in your PhD will likely come from interactions with your peers. We therefore suggest you try to get a sense of the community you would be joining (including how much interaction you are likely to have with others, how high performing the students are and what the work culture is like).
One way of gauging how high performing your peers would be is to look at the careers of alumni of the research group. You may also want to meet with some of the students you would be working with. The university's ranking should also serve as a reasonable heuristic. If you’re interested in learning more about university rankings and what aspects of them are relevant to PhD students, you could check out this article from findaphd and see the Times world university rankings.
If you're interested in working with a particular supervisor, we suggest emailing current and former students to ask about their experiences.
You could ask:
The importance of your supervisor’s and university’s reputation is different depending on whether you plan to stay in academia long term.
If you want to pursue an academic career it’s generally helpful to seek a supervisor with high prestige who will encourage you to publish (you can check if they have a track record of publishing with students and whether the papers are published in respected journals). The reputation of your PhD supervisor will also affect how a letter of recommendation from them is received if you apply for academic or postdoc positions later.
If you plan to pursue a non-academic career, a supervisor who encourages the development of transferable non-academic skills may be valuable, as well as someone who collaborates with non-academic organisations where you can do practical research. There are some careers outside of academia, such as policy and public-facing roles, where having attended a top university is particularly useful, but the reputation of your supervisor specifically is likely less important.
If you plan to leave academia, you should also consider whether you actually need to do a PhD to meet your career goals. You could read advice on the pros and cons of getting a PhD, for example here. We’d also suggest researching for yourself how common PhDs are amongst people who are where you would like to be in your career in the future and looking at the career trajectories they followed.
It’s unlikely that you’ll find a supervisor or research group that rates very highly on all these factors, so here are some of our thoughts on how the importance of them compares.
We think that working with a supervisor and research group with particularly strong research skills is more important if you want to stay in research long term, but if you’re pursuing a PhD primarily for having credentials, it’s not such an important factor. We think talking to other students about their experience of the culture you’ll be joining and looking at the kind of jobs they tend to obtain is also likely to be especially useful.
In terms of supervisor availability, it is worth considering how independent you already are as a researcher – some people prefer a supervisor who gives them less oversight. If a potential supervisor doesn’t seem very available, you may want to pay more attention to whether there are other researchers whose work you are excited about. If you’re in a collaborative setting, postdocs and experienced PhDs will likely play a key role in providing informal supervision.
As a prospective PhD student you may want to contact potential supervisors informally before submitting a research proposal, for example to find out if they are interested in your ideas and discuss what it would be like to work with them. However, it is sometimes against university policy to discuss a prospective application before applying officially, so check whether this is mentioned before reaching out.
Anecdotally, you’re more likely to be accepted if you have connected with a potential supervisor who is excited about working with you before submitting an official application.
Below are some tips for reaching out to potential supervisors.
Before you contact supervisors:
Be concise
Academics get a lot of emails, so give some thought to how you can make yours easy to engage with. We suggest:
Briefly and clearly describe your goals
If you’re not expressing interest in a PhD programme with predetermined research questions, explain the research you want to pursue, why you believe it is important, and, if possible, how your previous research connects and how it would fit into the broader picture of your goals.
Be informative
You should generally include:
Build connection
If you don't hear back
We suggest sending a gentle check-in email about a week later, and then it’s best to move on. Not hearing back doesn’t mean you got anything wrong – often academics simply have more emails than they can keep on top of.
If a prospective supervisor is open to meeting you, you could ask them if they want to see your research proposal prior to the meeting (this will also give you the chance to ask for feedback during the meeting).
In a meeting, you may find it useful to ask:
If you’re interested in finding a secondary supervisor, we suggest the first step you take is to discuss this with your primary supervisor once you’ve established a working relationship with them, to check whether they are supportive in principle. They may also be the best person to connect you with a secondary supervisor.
Finding a secondary supervisor can be particularly helpful if:
