Aquatic Amniote Paleobiology
I am broadly interested in vertebrate comparative anatomy, histology, and function, though I try to focus on the vertebrate transition from terrestrial to aquatic, particularly in the mammalian orders Sirenia, Desmostylia, and Cetacea. I am particularly interested in functional anatomy (especially as it relates to dental microwear) and histology (including confocal microscopy), especially of the integument, masticatory anatomy and mechanical properties of food tissues. I am also focused on identifying osteological correlates of soft tissues, and the testing of paleobiological inferences generally.

In addition, marine and terrestrial vertebrate faunas of Cenozoic of Eastern North America are also of keen interest, particularly with the apparent disparities between faunas of the NE and SE with the West. Lastly, I am interested in the systematics of a number of groups, including Sirenia, Desmostylia, Cetacea, and a number of terrestrial artiodactyl groups (Protoceratidae, Camelidae, Antilocapridae, Palaeomerycidae), including the origin of Ruminantia and Tylopoda.
