Roni Factor is an Associate Professor at the Institute of Criminology, Faculty of Law, the Hebrew University of Jerusalem. His research brings an interdisciplinary perspective to the question of how the macro-level social context influences individuals’ antisocial and criminal behaviors. In studying these issues, he employs cutting-edge quantitative methods, using a variety of different types of data and research designs. His research so far has focused on three main areas. In the first, he studies how the macro social context and people’s position in society affects high-risk and criminal behavior, with a particular focus on traffic violations and road traffic crashes. In the second, he explores community–police relations and the legitimacy of law-enforcement institutions. In the third, he asks whether there is racial or ethnic bias in the work of law-enforcement institutions and develop new tools to measure it.
