Global and Community Health

Lisa Cosimi, MD, earned a B.A. in Economics from Cornell University in 1992 and M.D. from the Weill Cornell Medical College in 1996. She completed her residency in Internal Medicine and Primary Care at the Massachusetts General Hospital and Infectious Disease training at the Mass General Brigham combined fellowship program, before joining Brigham and Women's Hospital as faculty in Infectious Diseases. She subsequently moved to Vietnam; she was based there from 2003-2007. While there, she trained and mentored HIV health care workers and was recruited by the U.S. CDC Global AIDS Program (GAP) Vietnam to lead the development of their HIV clinical programs and operational research efforts under the United States President’s Emergency Plan for AIDS Relief (PEPFAR). During this time, she became increasingly interested in the role that health system gaps play in the quality of care.

Dr. Cosimi’s current areas of research include developing and evaluating ways to strengthen medical education and health systems to improve healthcare quality in resource-limited settings. Her group, The Partnership for Health Advancement in Vietnam (HAIVN), brings together faculty, residents, and medical students throughout the Harvard Medical School community to partner with Vietnam’s Ministry of Health, Medical Universities and hospitals to reform and modernize health care worker education, and improve health system gaps and quality of health care throughout the country.

Alexander Tsai, MD, PhD, is a board-certified psychiatrist at Mass General, Associate Professor of Psychiatry at Harvard Medical School, and Associate Professor in the Department of Epidemiology at the Harvard T.H. Chan School of Public Health. Through his research he seeks to discern how large-scale social pathogens such as stigma, discrimination, and structural violence affect the distribution of mental health outcomes, with the aim of improving health equity worldwide.

Dr. Tsai is founding co-editor-in-chief of the journal Social Science and Medicine - Mental Health. 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. He was elected to the American Society for Clinical Investigation in 2021, to Distinguished Fellowship in the American Psychiatric Association in 2022, and to the American College of Psychiatrists in 2023.
