Dr. Tiffany L. Lemon is an HIV epidemiologist and a Research Fellow at the Massachusetts General Hospital Center for Global Health. Her research seeks to identify and quantify the impacts of psychosocial and sociopolitical factors that influence HIV disease progression and manufacture health inequities among marginalized populations. Dr. Lemon’s current work leverages high-quality data, causal inference methodologies and novel treatment heterogeneity assessments to estimate the effects of social and institutional policies on health care utilization, HIV disease progression, and health-related quality of life, specifically in the U.S. Deep South. Prior to becoming a Research Fellow at MGH, Dr. Lemon earned a B.S. in Biochemistry at Louisiana State University, an MSPH in Global Epidemiology from Emory University’s Rollins School of Public Health, and a PhD in Population Health Sciences from the Harvard T.H. Chan School of Public Health. As a pre-doctoral fellow, she was selected as a 2020-2021 Fostering Diversity in HIV Research Scholar. Dr. Lemon is mentored by Dr. Alexander Tsai.
