A precise control of cell morphology is key for cell physiology, and cell shape deregulation is at the heart of many pathological disorders, including cancer. Cell morphology is intrinsically controlled by mechanical forces acting on the cell surface, to understand shape it is thus essential to investigate the regulation of cellular mechanics.

In animal cells, shape is primarily determined by the cellular cortex, a thin cytoskeletal network underlying the plasma membrane. We investigate how the mechanical properties of the cell surface arise from the microscopic organisation of the cortex, and how changes in these properties drive cell deformation. Using a combination of cell biology experiments, quantitative imaging and physical modelling, we aim to understand the control of cell shape across scales.
