We study interactions between humans and their environment on a variety of temporal and spatial scales from Plio-Pleistocene hominins to modern humans. Much of this research is focused on soils or paleosols (fossil soils), but we study a variety of terrestrial environments including lakes, springs, and rivers. We are focused on using stable isotopes and geochemistry to answer questions about past climates or environments with a firm foundation in sedimentary geology. Study areas include North America, eastern Africa, Armenia, and Panama. For more information on how to join our research group, see the additional information for prospective students.
Emily earned her B.A. from Trinity University, M.S. from Rutgers University, and Ph.D. from Baylor University. You can learn more about her research interests here and read about them on Google Scholar.
Jarred is a third year PhD candidate in the Department of Earth and Environmental Sciences. His research interests are sedimentology, geochronology, and paleosols in order to study paleoclimates and paleolandscapes in North America. His work at the University of Minnesota will focus on paleoclimate reconstructions in the Wind River Basin of central Wyoming using stable and clumped isotopes. Another aspect of this project is establishing a magnetostratigraphic record to provide greater age constraints on the paleosols and fluvial deposits of the Wind River Formation. He attended Murray State University for his undergraduate degrees in Chemistry and Environmental Science.
Jim is a first-year MS student in the Department of Earth and Environmental Sciences. He attended Lawrence University for his BA in Geology (2012). His research interest are sedimentology, geochemistry, and fluvial geomorphology. His work looks at the Golden Valley Formation and Eocene paleosols of the Williston Basin, in southwestern, North Dakota. Jim hopes to reconstruct paleoclimate following the PETM through stable and clumped isotope analyses.
Madison is a 2nd year PhD student in the Department of Earth and Environmental Sciences. She attended CSUN for her undergraduate degree in Geology and her research focused on developing a paleosol paleoclimate proxy using seasonal climate conditions. Her work at the University of Minnesota will focus on reconstructing paleoclimate in the Baringo Basin of East Africa.

Andrew’s research interests include: paleoclimate, paleoecology, paleobotany, sedimentology, stratigraphy, and magnetostratigraphy. He is now a faculty member at New Mexico State University.
Nicky collecting water samples in Panama.
Prior to joining the lab, Nicky received her MS in water resources science and certificate in water conflict management from Oregon State University through the Peace Corps Masters International program. Nicky graduated from the University of Houston in 2024 with her doctorate and now works as a Hydrologist for the Water Accounting Division, International Boundary and Water Commission Headquarters in El Paso, TX.
