Dr. Farquhar received her MD at Harvard Medical School, and completed a residency and chief residency in internal medicine and a fellowship in infectious disease at the University of Washington, where she also earned a Masters in Public Health. She currently spends approximately 2 months each year in Nairobi mentoring US and Kenyan trainees and conducting research on correlates of immunity against HIV-1, HIV-discordant couples, and mother-to-child HIV-1 transmission. Ongoing studies explore immune responses in HIV-exposed, uninfected infants and adults, with a focus on examining basic science questions from an epidemiologic perspective.
She has published more than 75 peer-reviewed papers and is the Editor-in-Chief of the online journal, Retrovirology: Research and Treatment. Dr. Farquhar teaches 3 courses in the School of Public Health, AIDS: A Multidisciplinary Approach, the Responsible Conduct of International Research, and the Integrated Residency Global Health Leadership course. In addition, she sees HIV-infected patients one half-day per week at Madison Clinic and attends in the Infectious Disease clinic and on the wards at Harborview Medical Center.
