The theme of the lab is to understand how cells achieve a homeostatic mechanical state of their membrane during various processes/perturbations. We study how effective membrane tension (map: left) is interlinked with endocytosis, receptor clustering, cell-cell fusion, migration, and cellular mechanoprotection (cell rupturing, right).
