I am an Associate Professor in the Department of Natural Resources and Environmental Sciences at the University of Illinois Urbana-Champaign. My research seeks to understand how nitrogen is transported through landscapes and transformed biogeochemically along the way. I am particularly interested in how climate, soil, and landscape properties control these coupled processes. Working at the intersection of biogeochemistry, watershed hydrology, and soil physics, I develop and apply stable isotope techniques to trace water and nitrogen together. My work aims to advance fundamental understanding of coupled hydrological and biogeochemical processes while informing strategies to reduce nutrient loss from agricultural systems. I teach courses in Aquatic Biogeochemistry, Soil and Water Conservation, and Stable Isotope Ecology.
