Our research efforts are focused on the chemical processes that affect the fate of trace metals in natural and engineered systems. We study how chemical speciation of metals governs persistence, mobility and bioavailability in the aquatic environment. Our group is currently involved in the following projects:

Aggregation and stabilization of nanoparticulate metal-sulfides in the presence of natural organics

Mercury mobilization and methylation potential in restored and constructed wetlands

Oxidation of metal-thiol complexes

Oxygen, iron, and manganese flux at the sediment-water interface of hypolimnetic reservoirs.
