My research interests involve the paleoecology, biogeography, and evolution of Cenozoic mammals. Current research projects include: morphology and stable isotope ecology of American mastodons in the Atlantic Coastal Plain, morphology of Pacific mastodons in southern California, evolution and dispersal of the ancient whale Basilosaurus in the southeastern coastal plain of North America, and paleoecology and taxonomy of middle Pleistocene elephants from the Western Cape Province, South Africa. I am also interested in sclerochronology, and have applied sclerochronological techniques to teeth of mastodons, sauropod dinosaurs, and mosasaurs (extinct marine reptiles).
