Welcome! I am the Curator of Fossil Vertebrates at the University of Colorado Museum of Natural History and an Associate Professor in Geological Sciences at CU-Boulder. My research focuses on the study of mammalian faunas during past intervals of climate change as well as the recovery and evolution of mammals following the mass extinction at the Cretaceous-Paleogene boundary. My field research on fossil mammals takes me all over the Rocky Mountain Region and Canada's High Arctic.
