Dr. Christopher S. Koper is an Associate Professor in the Department of Criminology, Law and Society at George Mason University and the Principal Fellow of George Mason’s Center for Evidence-Based Crime Policy. Dr. Koper has 30 years of experience studying crime and justice issues at George Mason, the Police Executive Research Forum, the University of Pennsylvania, the Urban Institute, the RAND Corporation, the Police Foundation, and other organizations. He has written extensively on issues related to policing, firearms, federal crime prevention efforts, research methods, and other topics. Dr. Koper has served as a lead or senior-level investigator on numerous projects for the U.S. Department of Justice and other funders, and as a consultant to the attorney generals and city attorneys of several states and localities. Some of his most prominent works include: studies of the 1994 federal assault weapons ban; the Evidence-Based Policing Matrix tool for policy translation of research on police crime control strategies (http://cebcp.org/evidence-based-policing/the-matrix/); and the “Koper curve” principle of hot spots patrol, which is used by many police agencies in the United States and abroad. Dr. Koper is a fellow of the Academy of Experimental Criminology, the co-editor of Criminology and Public Policy (for issues starting in 2020), and the co-author of Evidence-Based Policing: Translating Research into Practice (Oxford University Press).
