My research interests are tied to the study of the origin and maintenance of biodiversity and the consequences of biodiversity loss throughout deep time. I seek to better understand the abiotic and biotic mechanisms that contribute to trends in the phylogenetic, morphological, and biogeographic diversity of extinct faunal assemblages. Currently, I study community assembly and faunal dynamics among mammal communities during the mid-Paleocene (Torrejonian-Tiffanian) of southeastern Montana.
