    Mark Siedner is an Assistant Professor in Medicine at Harvard Medical School and Assistant Physician in the Division of Infectious Diseases at the Massachusetts General Hospital. His research program, based in Durban, South Africa and Mbarara, Uganda, lies at the intersection between population health and clinical research, and is aimed at mitigating the causes of morbidity and mortality among people living with HIV in low-income countries.

    Projects include 1) directing clinical trials to evaluate scalable interventions to address structural barriers to care, including transportation costs and poor communication systems, 2) directing a longitudinal cohort study of aging HIV-infected persons and matched HIV-uninfected controls to discern the HIV-related epidemiology of aging in rural Uganda; and 3) leading an NIH and PEPFAR-funded randomized clinical trial to estimate the efficacy and cost-effectiveness of resistance testing to improve management of virologic failure. He also serves as the primary global health mentor to over a dozen medical students, medical trainees and journal faculty, and has been recognized for this work with the Harvard Medical School Young Mentor Award. Finally, he is a Visiting Associate Professor of Medicine at the Mbarara University of Science and Technology, where he teaches courses on epidemiology biostatistics, and grant writing.

  • Alexander Tsai, MD
    Research Scientist

    Dr. Tsai's research aims to understand how large-scale social forces such as violence, stigma, and water insecurity affect health and mental health in vulnerable populations. His principal research platform is a population-based social network cohort in rural Uganda. He is a Specialty Consulting Editor for Public Library of Science Medicine, where he handles manuscripts related to global health, HIV, psychiatry, and human rights. Prior to his appointment at Mass General, he completed a Robert Wood Johnson Health and Society Scholars postdoctoral fellowship at Harvard University and his residency training in general adult psychiatry at the University of California at San Francisco.
