Marie Ouellet is an Assistant Professor in the Department of Criminal Justice and Criminology at Georgia State University. She is interested in understanding how delinquent groups emerge and evolve, and how networks structure this process. Her main research applies network methods to the study of co-offenders, delinquent peer groups, gangs, and white-collar crime. Some of her current work draws on the policing subculture literature to explore how misconduct spreads through exposure to delinquent peers. Ouellet’s work has been published in Criminology, Journal of Research in Crime and Delinquency, and Social Networks.
