Main interests

Our group studies molecular and cellular processes that regulate tissue morphogenesis and repair. We are mainly focused on a simple model of epithelial resealing using Drosophila embryos and in natural occurring morphogenetic movements, such as dorsal closure, that has striking similarities to wound repair. We are also studying the mechanisms that regulate the recruitment of macrophage-like blood cells to wound sites to clear damaged tissue. More recently, we have started studying tissue regeneration and repair in a vertebrate model system, the zebrafish.
