Research
My primary research interests are in the general field of cell biophysics, more specifically, mechanics of the cytoskeleton, one of the main force-producing structure in the cell. My broad goal is to develop and study mechanical models to understand how cells control their shape, volume and motility to perform collective tasks and self-organize into tissues. These functions play a crucial role in many biological phenomena including wound healing, inflammation, remodeling of connecting tissues, rebuilding of damaged structures and formation of metastases in cancer. What mostly fascinates me in this type of research is the delicate and often unexpected interplay between biology and mechanics. I work on quantitative models that can, on one side, reproduce experiments and, on the other side, be thoroughly understood at the mathematical level. I enjoy the interdisciplinary nature of the projects where biology and physics are the fundamental starting points while mathematics is a powerful tool allowing one to achieve full clarity.
I am now a CNRS junior fellow (Charge de Recherche) at the Laboratoire Inter-disciplinaire de Physique.
