PhD Student in time-resolved structural biology of membrane proteins
The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2,300 people.
This PhD project is a part of a recently funded SNSF Ambizione grant. Our research aims to uncover the molecular mechanisms of human daylight vision by studying light-sensitive G protein-coupled receptors (GPCRs). We are utilizing high-resolution, time-resolved structural biology methods to capture the real-time interaction of these receptors with their signalling partners.
