Our team focuses on forces and movements of subcellular structures during cell division. We adopt a "systems" approach to decipher the mechanisms making the division robust to perturbations. Those are for example mechanical deformation or chromosome aberrations. Robustness is an ambivalent property because it allows proper development, from a one-cell embryo to a complex multicellular organism such as human, but also contribute to genesis and resisting of cancerous cells, because it allows tumor cells to resist anti-cancer drugs and to develop despite the many errors that they have accumulated.
