Research Interests

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.

Current Projects

•  Effects of global warming during the PETM on evolution of venericard bivalves along the Gulf Coastal Plain. 
•  Effects of climate change versus human disturbance on the evolution and ecology of Chesapeake Bay mollusks. 
  
•  Evolutionary history and systematics of veneroid bivalves.
  
•  Relationship between rarity and extinction during background intervals.
