Job Title
Assistant Professor of Environmental Engineering
Areas of expertise
Hydrogeology, Geochemistry, Surface Water Hydrology
Research interests
My research spans the fields of hydrogeology, geochemistry and water resources. I study how perturbations to the environment influence elemental cycling and the quality of our water resources. A main focus of my research has been on improving our understanding of the hydrologic and biogeochemical factors that result in the mobilization of naturally occurring arsenic from sediments into groundwater, which is a problem that threatens the health of millions of people around the world. One of the primary goals of my research is to help answer questions about how groundwater and surface water quality will change in response to natural and anthropogenic changes to the environment and what this means for the health of people and the environment.
