         The development of an embryo is based on the coordination of complex behaviors of a large number of cells. Our lab is interested in unravel these dynamics by filming single cells inside the live embryo. We use a quantitative live imaging approach across biological scales to visualize how embryonic cells cooperate to build an embryo from one single fertilized cell.


      The bioimaging technology allows us to perform a comprehensive analysis from gene expression to subcellular mechanobiology in zebrafish, mouse and human embryos, and synthetic tissues. We are particularly interested in the protective role of epithelial cells in tissue homeostasis, regeneration and immunity.
