Aaron grew up in rural Northeastern Pennsylvania. He studied mathematics at Hamilton College before spending a few years working in the lab at the NIH, where he developed a passion for the field of HIV while studying its immunopathogenesis. He attended medical school at the University of Pennsylvania, where he met his wife Emily. While in medical school, he worked on a research project focused on the potential for using deceased organ donors with HIV in Philadelphia. He and Emily moved to Boston for residency, where he completed the Howard Hiatt Residency in Global Health Equity and Internal Medicine at Brigham and Women’s Hospital. While there, he spent much of his last two years working in rural Haiti focused on HIV, tuberculosis, and cholera. While there he developed an interest in the intersection between food security and health outcomes, and in particular the role of social protection in the management of infectious diseases. Domestically he also focused on health equity work as a member of the Department of Medicine’s Health Equity Committee and as part of a team that led a racial justice analysis to improve care for patients admitted to our hospital with heart failure. After residency he spent a year as an HIV fellow at Brigham and Women’s Hospital while continuing his research in Haiti as a Global Health Fellow at Massachusetts General Hospital. Outside of work, he enjoys playing chess, running, playing his banjo/guitar/piano, and being a new dad.
