My research interest focus on aqueous geochemistry, chemical oceanography, and geomicrobiology. Our expertise is in the cycling of trace metals and inorganic chemical species at oxic-anoxic interfaces in freshwater and marine systems (water column and sediments). Our research involves extensive field and laboratory work as well as mathematical modeling.
