My research focuses on understanding major mass extinctions in earth history by employing multiple geologic tools to the same field area and questions. I received a B.A. degree in Geology from Macalester College (St. Paul, MN), and a Ph.D. from the Department of Earth & Space Sciences from the University of Washington (Seattle, WA).
My work has primarily involved stable isotope geochemistry, invertebrate paleontology, and sedimentology. Field work is an essential component of my studies, and my current field sites are on the Antarctic Peninsula, the Indian Subcontinent, and in eastern Montana, all focusing on the end Cretaceous mass extinction.
