Current topics include membrane-protein interactions with regard to membrane deformation or curvature sensing by BAR domains. Also, we study the dynamics of membrane tubes of both cells and simple model membrane tubes. Finally, we study membrane
phase behavior which has important implications for the lateral organization of membranes as wells as for physical properties like bending, permeability and elasticity.
At Stanford University, Boxer lab, I worked on membrane fusion of small unilamellar lipid vesicles to flat membranes tethered to glass surfaces. This geometry closely resembles biological systems in which
liposomes fuse to plasma membranes. The fusion mechanism was studied using DNA zippering between complementary strands linked to the two apposing membranes closely mimicking the zippering mechanism
of SNARE fusion complexes.
At Harvard University, Harvard soft matter group, I worked with reconstitutted contractile acto-myosin systems containing mainly actin, actin cross-linkers and myosin motors. Contractility and rheology of such systems was studied
using confocal microscopy and rheology.
Effect of membrane curvature on lateral distribution of membrane proteins
Several membrane proteins exhibit interesting shapes that increases their preference for certain membrane curvatures. Both peripheral and transmembrane proteins are
tested with respect to their affinity for a spectrum of high membrane curvatures. We generate high membrane curvatures by pulling membrane tubes out of
Giant Unilamellar lipid Vesicles (GUVs). The tube diameter can be tuned by aspirating the GUV into a micropipette for controlling the membrane tension. By using fluorescently
labled proteins we have shown that sorting of proteins like e.g. FBAR onto tubes is significantly increased for highly curved tubes (small tube diameter).
Membrane adhesion and phase behavior
At the Nanoscience center KU I worked with adhesion of membranes to substrates using advances quantitative microscopy techniques. Also, I studied phase behavior of small unilamellar lipid
vesicles with respect to their curvature.
Optical properties of nanoparticles
At the NBI I am involved in projects relating to optical properties of metallic nanoparticles in particular with respect to plasmonic heating with direct applications to
photothermal cancer therapy. For this purpose we have developed heating assays that can be used to measure the heating of any nanoscopic heat source like an irradiated nanoparticle.
"The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed."
