My research aims to improve public health decision making through data analysis and decision tools. Since 2002, my focus has been on food safety, namely the use of ranking and prioritization approaches to create more effective and efficient decisions at the state, national, and international level. My research is grounded in decision analysis and risk analysis approaches, and informed by a wide variety of disciplines - epidemiology, microbiology, simulation modeling, economics, expert elicitation, statistics, mathematics, and others. Decision making under uncertainty is of particular interest.
