Research interests include evolutionary systematics, biogeography, comparative morphology, and taxonomy, with special focus on marine Mollusca, especially Gastropoda and Bivalvia. As a “museum person,” he is particularly interested in the development and application of organismal, collections-based research, ranging from extensive new field surveys and large-scale specimen and data management issues, to the integration of morphological, paleontological, and molecular data to address biological research questions. He recently served as lead PI of the Bivalve Assembling-the-Tree-of-Life (BivAToL.org) effort and is involved in coral reef restoration projects and associated invertebrate surveys in the Florida Keys. Past offices include service as president of the American Malacological Society and of the International Society of Malacology (Unitas), and he currently is a chief editor in the MolluscaBase.org effort.
