The Distinguished Alumnus Award, established in 1988, was created to give recognition annually to an Alumna/us of UC Davis School of Medicine or the UC Davis Medical Center for contributions to society and distinguishing themselves through outstanding achievements in medicine. Garen Wintemute, M.D., M.P.H., is one of the nation's leading researchers in the field of epidemiology and prevention of firearm violence and he has done more than any other individual in medicine to translate the results of such research into effective public policy. After completing his medical training at UC Davis, Dr. Wintemute entered the private practice of emergency medicine. During his first year, he worked for six months in Cambodia with the International Committee of the Red Cross. His experiences in Cambodia and as an emergency medicine physician changed his career. Determined to refocus on prevention and policy issues, he obtained an M.P.H. degree in international health and injury epidemiology and then joined the faculty at UC Davis. Dr. Wintemute published three of the first papers ever to consider firearm violence from a public health perspective. Dr. Wintemute's accomplishments illustrate his effectiveness as a researcher, clinician, educator and an effective policy advocate.
