We offer several places for B.Sc. and M.Sc. theses every semester. PhD positions are regularly available through externally funded projects. With your own doctoral scholarship, you can also do your doctorate with us without vacancies. Through our strong (inter-) national network, our students learn specialized methods. As part of many projects, they are given the opportunity to spend time abroad. Our team is very international, so that meetings and discussions take place mainly in English. Thus, we also offer international young scientists an optimal working environment. We are always happy to receive unsolicited applications for S-module positions, theses, or doctoral positions. Please send an e-mail to Prof. Dr. Thomas Happe or PD Dr. Anja Hemschemeier.

Current job offers

A PhD position is immediately (April 2023) available in our group for the optimization of hydrogen-forming protein complexes in cooperation with Japanese and European researchers (3 years, 65% TVL-E13). The project involves experiments at the Institute of Protein Research, Osaka University in Japan.

Main research topics

Especially in the light of climate change, we need fundamentally new concepts to generate and use environmentally friendly and climate-compatible forms of energy, so-called 'green energy'. The main focus of the Photobiotechnology group is the study and biotechnological application of hydrogen-forming enzymes (hydrogenases) and other redox enzymes, which assume important functions in microbial energy metabolism (we mainly study photosynthetic microorganisms) or which catalyze industrially relevant chemical syntheses.

Molecular mechanisms of hydrogenases and their redox partners


Design of novel hydrogenases


Industrially relevant algal enzymes and biotransformation


Stress responses of microalgae
