Personal Statement:

Our research and educational programs are focused on understanding, assessing, and ultimately preventing adverse human health effects associated with exposure to environmental hazards. This includes effects resulting from exposure to direct or metabolically-activated genotoxins and mutagens such as ionizing radiation, hazardous air pollutants, elemental metals, and engineered nanomaterials. We develop and use markers designed to define mechanisms of toxicity that such agents cause directly to nucleic acids or indirectly through non-genotoxic mechanisms and their influence on disease outcomes.
