Research Interests

My research area is the evolution of the molluscan class Bivalvia (clams, scallops, oysters) with emphasis on morphology, ecology, geologic history, phylogeny, and systematics.  Basically, I seek to erase the artificial boundary between zoology and paleontology by applying the results of detailed studies of living bivalves to the interpretation of their fossil counterparts on a worldwide basis and extending through their entire 550 million year fossil record.  On the geological side, my work interfaces with the subdisciplines of biostratigraphy,  paleogeography, paleoecology, and ocean history; on the zoological side, it interfaces with functional morphology, biogeography, molecular genetics, and systematics.
