The research activities of our group aim to establish a fundamental, physics-based understanding of the function of bio-macromolecular systems. In this respect proteins and (protein based) macromolecular complexes, also within in their cellular context, are of particular interest for our research topics. The experimental techniques used are confocal fluorescence microscopy and simultaneous time-resolved multicolor detection. Thereby fluorescence correlation spectroscopy (FCS, nsFCS) and single molecule Förster resonance energy transfer (smFRET) are employed in our research projects.

Candidates (physicist, chemist, biophysicists) should have good experimental skills in working with optical research instruments, as well as in performing experiments and data analysis. Background in optics and laser spectroscopy is preferred. We are looking for an excellent and highly motivated candidate for research which is related to one of our current research projects:
