Alexander Tsai is an Assistant Professor of Psychiatry at the Massachusetts General Hospital, a faculty affiliate in the Harvard Center for Population and Development Studies, and an Honorary Lecturer at Mbarara University of Science and Technology in Mbarara, Uganda. His research, disseminated in more than 100 articles published in peer-reviewed journals, aims to understand how large-scale social forces undermine health and mental health in vulnerable populations. Among his current research projects, Dr. Tsai leads several studies on social networks, poverty alleviation, child development and clean water in South Africa and Uganda; and a U.S. national study elucidating the linkages between inequality of opportunity, health and human capital investments, and health outcomes. In 2011, he was awarded the APA/APIRE Health Services Research Early Career Award, which is given annually to one early career psychiatrist under the age of 40. Prior to joining the Mass General faculty in 2012, he completed a postdoctoral research fellowship in the Robert Wood Johnson Health & Society Scholars Program at Harvard University and his residency training in general adult psychiatry at the University of California at San Francisco.
