A crucial factor that prospective PhD students often overlook when looking for a position is the choice of supervisor(s). The right supervisors can make the journey a time of growth and achievement, while the wrong ones can turn it into a nightmare. Isabelle Kohler gives you the key aspects to consider when choosing a PhD supervisor, emphasizing the importance of a good fit not only for a successful PhD, but also for continued mentoring throughout your career.

I often have conversations with Master students about their career aspirations. We discuss what they plan to do after their studies and how they envision their careers developing. One common question is whether they should pursue a PhD, and if so, what steps they should take.

When Master students express an interest in pursuing a PhD, their primary concern is usually about the topic of their research. Will they be passionate enough about it? This is a valid consideration, as a PhD student will spend several years (usually four, sometimes more) immersed in their chosen subject. However, while passion for the PhD topic is important, an equally important but often overlooked factor is the choice of supervisor.

From my own experience, I know how important the role of a good PhD supervisor can be. I was very lucky to have three supervisors who were not only brilliant and respected scientists, but also great mentors. Their support extended well beyond my PhD years: they are still guiding me after more than a decade and we still have projects togethers. I’m very grateful for their support and the way they trained me during my PhD.

PhD supervisors can make your journey one of growth and achievement or turn it into a nightmare if the relationship is poor, your supervisor is unsupportive, or creates a toxic environment. But how can you know beforehand what they will be like? What should you consider when choosing a PhD supervisor?
