Projects will target fundamental problems in research fields dealing with vision, hearing, magnetoreception, olfaction and bacterial chemoreception. Thesis topics will address, for example, activation processes of receptor molecules, receptor-coupled signal transduction pathways and molecular switch mechanisms in components of these pathways. Moreover, the understanding of sensory phenomena in living systems is envisioned to benefit greatly from physical model systems and vice versa the biological systems could inspire the development of new technical applications (e.g. in biomedicine).
