The Biozentrum of the University of Basel in Switzerland invites applications for the Endress endowed professorship in Climate Biophysics, at either a tenure-track Assistant or tenured Associate Professor level. We encourage applications from candidates who explore fundamental molecular questions in climate-relevant fields, including biogeochemical cycles (e.g., carbon, nitrogen), bioenergetic energy conversion (e.g., photosynthesis, chemosynthesis), and the adaptation to environmental change. This call is open to researchers using various approaches, including molecular biology, microbiology, biophysics, structural biology, genomics, computational biology, synthetic biology, and environmental biology.
