Based within the School of Biosciences at the University of Exeter, our lab is currently studying mechanisms of embryo development in zebrafish, mangrove killifish, knifefish, pond snail and limpet. These embryos develop from a fertilised egg, undergoing many cell divisions and differentiation, rapidly becoming free swimming (or crawling) larvae. These dynamic events involve complex interactions of many gene functions. When gene functions are modified because of an alteration occurring in the gene (genetic mutation) or by environmental changes (e.g. chemical pollution, climate change, water acidification), normal embryo development is disturbed and disease may occur. We are studying how such genetic mutations and environmental changes affect healthy development of embryos and larvae. Our research contributes to our knowledge of environmental and genetic impacts on health in animals and humans.
