Our research group addresses fundamental problems in geobiology, with particular focus on subseafloor life. We analyze the composition and diversity of microbial communities in seawater and sediment. We study the evolution of subseafloor communities. We document the structure of subseafloor sedimentary ecosystems and the processes that nourish them. We assess the extent to which environmental properties limit the existence of life. We test the dependence of subseafloor ecosystems on the surface world. We assess their effects on the composition of Earth’s ocean, atmosphere and mantle.
