Immunologist Peter Doherty, the only veterinarian ever awarded a Nobel Prize, will discuss virus infections during a public talk Monday, Sept 18, at the UC Davis School of Veterinary Medicine, during the school's annual Oscar O. Schalm Lecture. The lecture, "Dealing With Virus Infections," will be presented to veterinary students, scientists and the general public from noon to 1 p.m. in 170 Schalm Hall, located in the medical sciences complex of UC Davis. Australian-born Doherty, who is a professor of pathology at the University of Tennessee, Memphis, Health Sciences Center and chair of Immunology at St. Jude Children's Research Hospital in Memphis, received the 1996 Nobel Prize in physiology or medicine along with colleague Rolf M. Zinkernagel for their discovery of the process by which the immune system recognizes virus-infected cells. Their research led to advances in efforts to bolster the immune system's defensive response to invading microorganisms and certain types of cancer. Their findings also advanced efforts to diminish the effects of autoimmune reactions in diseases such as multiple sclerosis and diabetes. Describing himself as an "experimentalist at heart," who intellectually "marches to the beat of my own drum," Doherty qualified in veterinary medicine at the University of Queensland, Australia, in 1966 and received a doctoral degree in pathology from the University of Edinburgh, Scotland, in 1970.
