Biomonitoring of human exposure to environmental chemicals; biomarkers of health effects; sources and pathways of human exposure; environmental distribution, food chain transfer and fate of organic pollutants; consumer product analysis; overdose and wastewater surveillance

We develop and maintain robust ICP-MS methodologies to support both human biomonitoring studies and emergency preparedness.

We study human exposure to toxic metals/metalloids (biomonitoring) and long-lived nuclides (radiobioassay); and develop novel speciation methods by coupling LC and GC to ICP-MS, while using portable XRF for field-based studies.

We develop analytical methods to identify unknown chemicals in foods and environmental samples including toxic compounds and chemical terrorism agents, thus providing national surveillance of the food supply.
