Jared Baeten, MD, PhD is a professor in the Departments of Global Health, Medicine and Epidemiology at the University of Washington. He is the Director of the UW/Fred Hutch Center for AIDS Research. His research focuses on epidemiologic and biologic risk factors for HIV-1 and other sexually transmitted diseases, and clinical trials of novel interventions for prevention of HIV-1 transmission. He co-chaired the Partners PrEP Study, a phase III, randomized clinical trial among HIV-1 uninfected heterosexual men and women in Kenya and Uganda that demonstrated pre-exposure prophylaxis (PrEP) provided protection against HIV-1 acquisition. Linked projects included a large observational study of PrEP adherence and laboratory analyses of innate and adaptive immune responses related to PrEP use.
