Epidemiology is a multidisciplinary study of distributions and determinants of health and performance in populations. The goals are to provide a scientific basis for preventing, controlling, and eradicating disease and for enhancing well-being and productivity in populations.

The mission of the Graduate Group in Epidemiology (GGE) is to provide through instruction and research the graduate academic education necessary to prepare individuals to be leading researchers in epidemiology, or to apply epidemiology to their discipline.

Faculty interests include environmental and occupational health, veterinary medicine (livestock, wildlife, laboratory animals, companion animals), biostatistics, economics, nutrition, international nutrition, infectious diseases, community health, and entomology.
