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. I also serve as the Director of the Museum & Field Studies Masters Program. 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.
