Dan Belsky's research is focused on understanding why socioeconomically disadvantaged populations face shorter healthy lifespans, with the aim of improving intervention strategies to mitigate this health inequality. He is an epidemiologist working at the intersection of genetics, the social and behavioral sciences, and public health. His work brings together discoveries from the cutting edge of genome science with longitudinal data from population-based cohorts and randomized trials to identify mechanisms that cause accelerated health decline in older age.

Daniel Belsky is Assistant Professor at Columbia University's Mailman School of Public Health. Prior to coming to Columbia, Belsky was Assistant Professor of Medicine and of Population Health Sciences at the Duke University School of Medicine, where he previously completed a postdoctoral fellowship at the Center for the Study of Aging and Human Development with Terrie Moffitt and Avshalom Caspi.
