Kathleen M. Powis

Assistant Professor, Harvard University

Kate Powis, MD, MPH, MBA is an Assistant Professor at Harvard Medical School with clinical appointments in Internal Medicine and Pediatrics at Massachusetts General Hospital and a research appointment in the Department of Immunology and Infectious Diseases at Harvard T.H. Chan School of Public Health. Kate’s research is focused on etiologies underlying health disparities of HIV-exposed uninfected infants and children in resource-limited settings and she is conducting clinical trials to identify feasible mechanisms to mitigate disparities. She is currently following a cohort of HIV-exposed uninfected infants in Botswana to explore the evolution of gut microbiome in the first year of life and determine whether differences in the evolution of gut microbiome between HIV-exposed uninfected infants and HIV-unexposed infants results in differences in immune system development and functioning. In a Kenya-based study, she is exploring whether a multi-sectoral intervention targeting food insecurity in HIV-affected households can improve health, growth, and neurodevelopment of HIV-exposed
