My research interests have evolved from studies of basic metabolism in ruminants and genetics to veterinary epidemiology, economic modeling and food safety. As an epidemiologist in food supply veterinary medicine, my goal is to identify economically optimal ways to manage health for animals and humans. This requires considering the whole food supply chain, in its full complexity.  This systems approach research merges tools from molecular biology, applied mathematics and social sciences. The two main areas of investigations currently ongoing in my laboratory are: 1) mathematical modeling of zoonotic infectious diseases, and 2) optimizing health and management decisions.
