The flows of energy, nutrients and contaminants structure the ecosystems that all life depends on. Our lab aims to understand how humans are modifying these flows. Research in our lab follows the movement of carbon, nitrogen and other elements through soils and the streams that drain them. We are particularly interested in mechanisms of soil organic matter stabilization, redox-sensitive processes, and hydrologically-integrated biogeochemical understanding. Using tools from ecology, hydrology and geochemistry, we examine these topics on scales ranging from the soil profile to large river basins. Work in the lab has previously focused on forests and agroecosystems, but we are interested in human-impacted ecosystems broadly.
