Service
I serve the greater community of food and agriculture, education and research through active participation and service on local, state, national and international boards of organizations relevant to my areas of expertise. I have represented the United States on several European Union – U.S. food safety initiatives evaluating science policy as related to foodborne pathogens and antimicrobial resistance.
Teaching
I teach the advanced epidemiological methods and data analysis to graduate students, as well as contributing to the DVM teaching of epidemiology, food safety, and public health. I also teach a seminar course in disease detection, surveillance, and risk analysis for animal health and food safety applications.
Research
My expertise centers on valid analytical and descriptive epidemiologic study design, conduct, and analysis in both public health and veterinary fields. I am particularly interested in applying empirical data arising from appropriately designed field studies to developing mathematical models of the microbial ecology in food production systems. My present research interests include: food safety issues such as pre-harvest ecology and management of antimicrobial-resistant bacteria and foodborne enteric pathogens, the epidemiology of Johne's disease (Mycobacterium avium subsp.paratuberculosis) in ruminants, decision-support systems for agro-terrorism defense, estimating interspecies contact between wildlife and domestic animals, studying the potential impacts of global climate and ecosystem changes on animal and human health.
