Meet Our Team

Scientific discovery and communication is a team effort. Our science is performed in collaboration with researchers from institutions around the USA and abroad, and often with local, State, and Federal stake-holders.

Darren J. Larsen

Associate Professor

Ph.D. University of Colorado, Boulder & University of Iceland

M.S. University of Colorado, Boulder

B.A. Colby College

Dr. Darren Larsen is an Assistant Professor in the Department of Geology at Occidental College. His research interests lie at the intersection of paleoclimatology, Quaternary science, and geomorphology, where he uses a range of tools, field observations, and analytical techniques to answer questions in these highly interdisciplinary fields. Much of this work involves investigating sedimentary archives to develop a greater understanding of Earth’s climate system and surface processes. He is especially interested in the sedimentary record of abrupt climate change, glacial-lacustrine sedimentation, and neotectonic activity in Arctic and alpine regions, as well as landscape evolution and the interaction of living organisms with their physical environment. 


Sarah E. Crump

NSF Postdoctoral Fellow

B.A. Carleton College

Ph.D. University of Colorado Boulder

Dr. Sarah Crump is a paleoclimate scientist who applies an interdisciplinary, earth systems framework to pursue questions of modern relevance. Her primary interests lie in developing sedimentary records of past warm periods and episodes of abrupt climate change during the Quaternary. She aims to document the pronounced environmental effects of past climate change in Arctic and alpine settings, including ecosystem and cryosphere responses. Her toolkit includes molecular lake sediment analyses, particularly sedimentary ancient DNA, as well as cosmogenic radionuclide dating of glacial deposits. She is also committed to broadening participation within the earth sciences and improving the communication of science outside the academic realm.
