The PhD journey: how to choose a good supervisor

Shared interests are the building blocks of your relationship

"Choosing a supervisor is tricky because you don't know much about them until you start working with them," says Lewis Wolpert, professor of biology at University College London. "Instead, start by choosing a problem that interests you - it's easier to do and just as important."

"It might sound obvious," says Jim Hough, director of the Institute for Gravitational Research at the University of Glasgow, "but it's amazing how many students don't do that."

John Cowpe, a second-year PhD student from the University of Salford, agrees. "To get the most from your supervisor, you have to be interested in what they do. My supervisor will leap at any chance to discuss - often at great length - a topic he's passionate about. You learn just as much from anecdotal chatting as you do from your own research."

A good supervisor says all the right things

Your supervisor will be a mentor, friend, confidante, adviser and also a voice of reason, so make sure it's a voice you'll want to hear. "Over the course of three years, it's crucial to have someone who can encourage you when your experiments fall flat, challenge you when you become cocky and help steer you towards successfully submitting your thesis," says broadcaster and writer Simon Singh, who did a PhD in particle physics at the University of Cambridge.

Choose a supervisor who excites you

It is essential to find a supervisor you believe in and whose work you find exciting, says Susan Greenfield, professor of physiology at the University of Oxford. "Scientists are made up of all types of people - thinkers, dreamers, practical workers - all of whom are important, but you need to find someone who thinks in the same way that you do."

You'll see many of your peers going to the City and into industry, earning much higher salaries than you, and who also seem to have more time off, says Greenfield, "so it's vital that you have a real passion and belief in your work".

Supervisors can be stereotyped - pick your favourite

So says David Hand, professor of mathematics at Imperial College London. "At one extreme, there are the most eminent senior academics with considerable experience. Their reputation and influence can rub off and they can introduce you to other big names, but they may not be able to give you as much of their time as is desirable."

At the other extreme is the junior academic, says Hand. While they have less experience, they have more time to spend on your project. This is an important factor to consider, says Vivienne Raper, a recent PhD graduate from the University of Bristol. "If you're not at your most motivated, an absent or distant PhD supervisor can be a recipe for months of procrastination."

Another option is to choose a supervisor close to retirement, suggests second-year PhD student Stefan Rohrmoser from the University of Southampton. "They are more likely to have a relaxed attitude, as they've seen it all before. Their students won't be running blindfolded into an overly ambitious project. They will be given interesting work which their supervisor knows is going to provide enough results to comfortably finish a PhD."

Personal chemistry is important

Once you've found a supervisor you'd like to work with, go and meet them, says Greenfield. "The real issue is to see whether the chemistry is right," she says. "Think about whether your prospective supervisor seems like the sort of person who will be there when you need them."

While you're visiting potential supervisors, try to meet some of their current students as well as other colleagues in their group. "I always tell PhD candidates to talk to my students," says Carolyn Stephens, senior lecturer in international environmental health at the London School of Hygiene and Tropical Medicine. "They know things about me that I don't know myself."

You can get a real feel for the mood of a department by chatting to current PhD students, agrees Singh. "Buy them a coffee and a doughnut, and ask them if they enjoy being part of the research group."

See a variety of people

If you have the opportunity to sample different supervisors at the beginning of your PhD, definitely take it, says Gerd Gigerenzer, director of the Max Planck Institute for Human Development in Berlin. "That gives you more time to work out who you would work best with."

Research councils are also starting to move towards multidisciplinary projects, which means you might get to work with more than one team, says Stephens. "There's a lot of encouragement to cross boundaries between disciplines. If this is the case, make sure your supervisor is willing to put you in touch with scientists from other subjects."

You will also find help from those closer to home. "Remember that on a day-to-day basis you will spend more time working with students and postdocs than your supervisor," says Hough. "So it's important that there's a good social environment. Usually that means a reasonable-sized group." This was important for Singh: "Being surrounded by postdocs, lecturers and other postgraduates willing to advise and guide me was invaluable."

Keep channels of communication free from static

If you feel like your supervisor is talking in a foreign language, don't panic. "Often in one-to-one meetings, you will understand what your supervisor says at a basic level, but will only have a good grasp of the implications and ramifications towards the end of your PhD," says Hand. "Don't be afraid to ask questions if you don't understand," agrees Gigerenzer. "Openness is key."

Prepare to take the reins

"A PhD is part apprenticeship and part equal partner. Ideally, the balance between these two modes shifts to the latter as time goes on," says John Krebs, professor of zoology at the University of Oxford. "It's a bit like learning to ride a bike," says Greenfield. "You start off on the back of your mother's bike. Then you get your own tricycle, then a two-wheeled bike with stabilisers. Finally your stabilisers are removed."

Science shouldn't be too safe; you shouldn't be too protected, she says. "Being trained to cope with failure is one of the most important parts of your PhD. If you don't know failure, then you're not being stretched enough." That said, you will reach the point where you know more than your supervisor about a specific aspects of your research. "This should certainly be your goal," says Gigerenzer.
