We investigate applications of biogeochemistry and ecosystem engineering to problems in water quality and greenhouse gas emissions from environmental processes.  Much of our current research focuses on the use of nature-based treatment technologies (e.g., denitrifying woodchip bioreactors; wetlands) as sustainable and cost-effective tools for controlling water pollutants from non-point sources.

Members of our group pursue research in the following areas:

Real-Time Control of Woodchip Bioreactors


Carbon Bioavailability in Woodchip Bioreactors


Arsenic Biogeochemistry in Rice Paddy Soils








Organic Matter Transformations in the Wetland Rhizosphere


Manganese Dynamics in Stratified Drinking Water Reservoirs
