I am a postdoctoral fellow at the University of Pennsylvania's Department of Criminology and the Penn Injury Science Center, part of the Perelman School of Medicine. I am a scholar of crime and criminal justice, urban sociology, the life course, and racial and ethnic stratification.

My recent and ongoing research falls into two broad categories. One is about police behavior, especially better understanding racial inequalities in policing, and how policing is shaped by neighborhood and organizational contexts. My other research seeks to extend the life-course perspective in the study of crime and criminal justice, so that we may better understand how social change impacts crime and its sanctioning, the dynamic processes that produce group-level inequalities, and—most generally—the ways in which human development is impacted by contextual influences over people’s lives. My research has appeared in journals such as the American Journal of Sociology, the Proceedings of the National Academy of Sciences, and the Annual Review of Criminology.

I hold a Ph.D. in sociology from Harvard University. Prior to that, I obtained my B.A. and M.A. from McGill University.
