Major Research Interests

How does evolution work? Although (since Darwin) the principles of biological evolution are known, we are unable to predict her course. Rapid biotechnological advances allow, however, a direct view onto the temporal changes in the genome. The group applies methods of statistical physics and nonlinear dynamics to develop theoretical models of molecular evolution that are tested with genomic data or in experiments.

Partially related biophysical projects deal with microbial morphogenesis. We use a combination of theory and experiments to test our understanding of the viscoelasticity and hydrodynamics involved in the fromation of self-organizing microbial populations (biofilms).
