Department of Geological and Environmental Sciences

Dr. Sarah Evans joined the department as an Assistant Professor in Fall 2017 from the University of Colorado at Boulder. She is a hydrologist who uses a combination of numerical modeling, field instrumentation, and remote sensing to examine how Arctic water resources are evolving in a warming climate. Dr. Evans is one of the primary faculty active in the Environmental Science degree tracks and the Environmental and Quantitative Geology tracks. 

Dr. Evans was awarded a National Science Foundation CAREER grant in 2023 and won the College of Arts and Sciences William C. Strickland Outstanding Junior Faculty Award in 2022.
