David Harding studies poverty and inequality, urban neighborhoods, education, incarceration, and prisoner reentry. He uses both qualitative and quantitative methods. His current projects include the social and economic reintegration of former prisoners, neighborhoods and prisoner reentry, the effects of incarceration on crime, employment, and health, causal inference for contextual effects research, for-profit colleges, educational attainment, and labor market outcomes, and the role of neighborhood context in adolescent romantic relationships and sexual behavior.
