Paleoecology and vertebrate paleontology, particularly the biostratigraphy and paleogeography of southern North America in the Tertiary; early and middle Tertiary mammals; the Cretaceous-Tertiary and Paleocene-Eocene transition, especially in Big Bend, west Texas; Louisiana fossil vertebrates; fluvial deposition.
A current major interest is the Miocene (Middle of the Age of Mammals) in Louisiana. A ten year project has yielded a diverse fauna of terrestrial, freshwater, and marine vertebrates, including rhinos, giant camels, whales, and gomphotheres.
