Emeritus Research Professor
Dr. Cohen's research analyzes many aspects of crime and criminal justice policy, including demographic trends in crime and prison populations, patterns of individual criminal careers, and incapacitative effects of incarceration.
Recently, her work has focused on various aspects of illegal drug use and its relationship to violent offending, the increasingly important role of firearms in youthful violence, and investigations of the effectiveness of policing and housing strategies in reducing violence.
Dr. Cohen has contributed to the work of several panels convened by the National Research Council to examine research on deterrence and incapacitation, sentencing policy, patterns of offending during criminal careers, and the understanding and control of violent behavior. She has served on the editorial boards of Criminology, Law and Society Review, Journal of Quantitative Criminology, and as Associate Editor of Management Sciences, Evaluation Review, and Criminal Justice and Behavior.
