I have experiences in the fields of metal biogeochemistry, biochemistry, ecotoxicology, exposure and risk assessment, and analytical chemistry of heavy metals. I am interested in the geochemical influences on metal bioavailability, toxic effects of metals on individuals and populations, source tracking of mercury in the aquatic and terrestrial systems, environmental fate of PFAS, molecular toxicity, human/ecological exposure modeling and risk assessment.
