Dr. Lauren Simkins is an Assistant Professor in the Department of Environmental Sciences at the University of Virginia. She graduated with a BS from Oklahoma State (2009), a PhD from the University of California Santa Barbara (2014), and was a post-doc at Rice University prior to arriving at the University of Virginia in 2018. Lauren uses the geologic record to inform contemporary glacial processes and marine-based ice sheet behavior. Lauren is a member of the Choctaw Nation of Oklahoma and of Cherokee and European (white) descent.

Graduate Researchers
|
Allison Lepp is a PhD student on the Thwaites Glacier Offshore Research (THOR) project, part of the US-UK International Thwaites Glacier Collaboration. Her work uses seafloor sediments and sediment porewater to better understand subglacial meltwater drainage and its influence on grounding line behavior. She holds a MS degree in Earth and Environmental Science from Montclair State University (2018) and a BS degree in Geology from Georgia State University (2014).
