My primary research interests are in the systematics and morphological evolution of edentate mammals (including anteaters, sloths, armadillos, pangolins and related fossil forms). In addition, I am interested in the biodiversity and biogeography of living mammals in southeastern Tennessee. I am also working on a long-term project involving the recovery and analysis of Late Pleistocene vertebrate faunas from Lookout Mountain, TN, in order to better understand the historical biodiversity, biogeography, and paleoecology of southeastern Tennessee vertebrates.
