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
Global Environmental Health and Mercury
Energy and Environment: Environmental impacts of coal ash disposal
Waste-to-Resources: Rare Earth Element Recovery From Geological Residuals
