The overall goal of my research is to understand how extinction and environmental change influence the evolution and ecology of fossil marine invertebrates. My research interests are broad and range from the influence of the K/T mass extinction on bivalve evolution, to the taphonomy and historical ecology of Holocene benthic mollusks in the Chesapeake Bay, to the effects of early Cenozoic global climate change during the early Cenozoic on venericard bivalves along the Gulf Coastal Plain.
