My recent project focuses on cell polarization and takes place in collaboration with the group of Roland Wedlich-Söldner at the Max Planck Institute of Biochemistry in Martinsried. The aim of our project is to understand in general how the dynamic and stochastic processes of cell polarization are regulated to create and maintain a unique and stable symmetry axis at fixed places for surprisingly long times.

To this end we consider yeast as one of the best studied model systems in biology. The major role in this polarization process is played by the small GTPase Cdc42p, a protein which is located on the plasma membrane and which exists in an active and an inactive state. The active form of Cdc42p interacts with other proteins to regulate cell processes necessary for cell polarization. The joint project includes experiments with living cells as well as making predictions from theoretical modeling which are verified by our experiments.
