Her research interests are in environmental health microbiology with a focus on water quality. She is developing novel tools and technologies to detect and track pathogens in water. She is also interested in evaluating impacts of non-point source pollution, and in evaluating the manner in which land-based activities (e.g., development, stormwater management, agricultural practices) can affect human exposure to microbial contaminants. Overall, this research is leading to a greater understanding of how environmental conditions can affect human health, and how humans themselves influence this process.
