Research Interest

I am a vertebrate paleontologist and my research interests focus on understanding paleoecological responses due to climatic events, extinctions, and the evolution of novel food resources. My main areas of interest are in the emergence of modern mammal groups during the Cretaceous Period and mammalian megafaunal response to climate during the last Ice Age. Current projects include describing terrestrial vertebrate faunas from the Late Cretaceous of western North America and understanding the taphonomy, chronology, and paleoecology of megafauna mammals at the Rancho La Brea Tar Pits.
