Our research focuses on membrane biophysics of living cells and biomimetic model systems.

Research synopsis

Although many vital biological processes have been characterized in extensive detail with regards to contributing players and pathways, physical phenomena like self-organization or diffusion are always present, but not always in the picture. We are interested to elucidate from a physicist’s point of view how membrane processes affect biological functions like cell-cell adhesion, signaling across membranes or defense strategies of parasites. Inherently, these involve a multitude of players and processes. This complexity renders a quantitative approach extremely difficult. Thus, biophysical studies often employ simplified model systems that contain only the key elements. Wherever feasible, comparable in vivo measurements in mammalian culture cells or model organisms are sought for. In order to bridge between both extremes, we are developing advanced cell models.

Our research on membrane biophysics is based on modern light microscopy techniques, especially single-molecule fluorescence microscopy to study dynamic processes and super-resolution microscopy to resolve nanometric structures. Application of these techniques to living cells, in particular swimming flagellates, is highly challenging but feasible.

Cell Adhesion is more than a handshake between binders. What role does physics play?


We employ cell models and model cells to shed light on membranes as multitasking organelles at the cellular interface with the outside.
