I am lecturing on various Master’s and PhD level courses on topics including the adaptive immune system, cell signaling, cytoskeleton, and microscopy. I have been involved in designing new courses targeted for PhD students and postdocs. I have done University Pedagogics 1 course to develop my pedagogic skills. At every day level, I am supervising doctoral students, postdocs, as well as guide Master’s thesis projects.


B lymphocytes are key cells in mounting the adaptive immune response by differentiating into antibody secreting plasma cells. Our group is interested in the molecular mechanisms of B lymphocyte activation, with emphasis on receptor activation and its immediate cell biological responses, typically culminating at the reorganization of the actin cytoskeleton, plasma membranes and intracellular traffic. In our research, we take advantage of both in vivo models and various advanced imaging techniques, including super-resolution microscopy, as well as modern proteomic approaches such as APEX2 proximity biotinylation.
