The primary focus of my research group on "Systems Biochemistry" is to reveal the molecular mechanisms that regulate changes in cell morphology through the cytoskeleton and the underlying polarization of the signaling molecules that control these processes. Instead of studying membrane polarity and cytoskeletal morphogenesis in their complex cellular environment, we aim to reconstitute these processes in minimal systems from purified components in vitro. This allows us to study and manipulate all biochemical activities in great detail to reveal the fundamental principles underlying self-organization of morphogenic signaling systems. As part of the MaxSynBio initiative and in synergy with recent research innovations in the Bastiaens department, we develop novel concepts and cutting edge methodology in systems biochemistry (multiprotein reconstitution, encapsulation) and combine these approaches with advanced fluorescence imaging (TIRFM, FLIM).
