Membrane Biochemistry and Lipid Research

Group leader


Research focus

The overarching topic of my research group is membrane biochemistry of cellular signalling. We investigate the interdependence of lipid-protein interactions through an interdisciplinary approach combining cell biology and synthetic biology as well as protein biochemistry, structural biology and biophysics. Our strong expertise enables us to study phenomena based on lipid-protein interactions at different levels - from the organ and cell systems down to minimally synthetic systems in which we can control both proteins and lipids, for example to observe the allosteric effects of certain lipids on basic receptors such as the EGF receptor (Coskun et al., 2011, PNAS) and the insulin receptor.
