My research centers on two areas: extinction theories and invasive species. On the northeast coast of the US, two species of crab from Asia and Europe have destroyed the softshell clam industry and are altering the ecology of the beaches that they have invaded. I study the impacts of these two species on the invaded areas and the factors that control the size and distribution of populations of these two crabs. I also use benchtop populations of zooplankton (small aquatic animals that can easily be kept as entire populations in the lab) to study extinction theories, which are traditionally difficult to test (it isn't very ethical to cause the extinction of a natural population just so that we can study it on its way out.) My goal is to improve our understanding of the extinction process so that we can more effectively prevent it.
