We are recruiting a PhD student in the lab of Prof. Claudia Bank at the Institute of Ecology and Evolution, University of Bern. The last date of application is 9 January 2026. A fully funded 4-year PhD position, supervised by Suman Das and Claudia Bank, is available in our group at the University of Bern, Switzerland. The position is part of the SNSF project "Navigability of rugged fitness landscapes: determinants, consequences, and evolutionary feedback", in which we study adaptation from a fitness-landscape point of view. The PhD project is theoretical in nature and will involve mathematical modelling, computer simulations, and/or data analysis. We welcome applications from diverse scientific backgrounds (e.g., from physics, mathematics, statistics, computer science, biology). We are particularly interested in candidates who are fascinated by evolutionary biology, have a strong background in mathematical modelling and enjoy programming. Please see the link for further details. Please reach out to Suman Das (suman.das [at] unibe.ch) in case of questions.
