Research Interests

  • The research in my lab addresses a variety of fundamental questions about how historic biogeographic and contemporary ecological processes together shape patterns of organismal diversity, particularly in the world’s oceans. I am most interested in molecular genetic approaches that can provide insight into the demographic histories of populations, the biogeographic histories of species, and the historic assembly of entire communities. I am also involved in basic and applied research that can assist with the management and recovery of vulnerable and over-exploited species. Current projects include the study of sister-species isolated by the rise of the Central American Isthmus, the genetics of recruitment in the bay scallop (Argopecten irradians), effects of Pleistocene climate change on rocky-shore community composition in the North Pacific, and forensic genetic analysis of commercially harvested species.
