We study biogeochemical processes that affect the fate of trace metals in natural and engineered systems. A central theme to our work is the utilization of chemical speciation for understanding and predicting the persistence, mobility and bioavailability of metals and minerals in the aquatic environment. Our group is currently involved in the following projects:


Mercury Biogeochemistry: Bioavailability and methylation potential of mercury sulfides






Energy and Environment: Environmental impacts of coal ash disposal and opportunities for reuse





Environmental Nanogeoscience





Global Environmental Health and Mercury
