Her research broadly focuses on applications of quantitative risk assessment to environmental hazards for ensuring water quality, food safety and addressing other exposure pathways. She is keenly interested in supporting environmental and human health decision making about how to mitigate risks from exposures to contaminates through the use of integrated risk and decision frameworks.
