My biogeochemistry research team studies interactions of hydrological, geochemical, and biological processes in
regulating surface and ground water chemistry. This research provides information to help guide the management of agricultural and wildland ecosystems in a sustainable and environmentally responsible manner.

In general, I am interested in the effect of anthropogenic and natural "disturbances" on biogeochemical processes and nutrient cycling/spiraling in aquatic ecosystems and implications for water quality and food web resources. I am just beginning to work on questions involving organic matter dynamics, stable isotope ecology, and ecological stoichiometry. I am also interested in practical applications of water quality monitoring and use of biological organisms as indicators of ecosystem health, as well as the structure and function of alpine freshwater ecosystems.

My current research focuses on the biogeochemical cycling of nutrients in constructed wetlands with an emphasis on the phosphorus cycle. My current research projects include: (i) phosphorus-iron-sulfu cycles at the sediment-water column interface, (ii) the temporal and spatial variabiliity of net ecosystem production in a constructed wetland, and (iii) the retention and transformation of reducible phosphorus in a constructed wetland. Other research interests include water quality, geostatistical modeling, and GIS and remote sensing.
