David Pyrooz (2011 Fellow) is an assistant professor in the Department of Criminal Justice and Criminology at Sam Houston State University. His research focuses on gangs and criminal networks, developmental and life-course criminology, and criminal justice policy and practice. David's GRF award supported his dissertation research on the economic and educational consequences of gang membership in the life course. "It was a great honor to receive the GRF, which was instrumental in establishing a research agenda that moved beyond static views of gang membership, that is, uncovering different pathways into and out of gangs and the implications of these pathways for both crime and achievement in the life course," he says. David is currently an investigator on two NIJ-funded projects, where he is applying the lessons learned from his GRF award to the study of the overlap between street and prison gangs and a comparative study of gangs and domestic extremist groups.
