Dr. Christopher S. Koper is an Associate Professor in the Department of Criminology, Law and Society at George Mason University and a senior fellow in George Mason’s Center for Evidence-Based Crime Policy.  Dr. Koper holds a Ph.D. in criminology and criminal justice from the University of Maryland and has over 20 years of experiencing conducting criminological research 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 and published extensively on issues related to firearms, policing, federal crime prevention efforts, research methods, and other topics.  Dr. Koper has served as a lead or senior-level investigator for numerous projects funded by the U.S. Department of Justice, including Congressionally-mandated assessments of the 1994 federal assault weapons ban and the federal Community Oriented Policing Services (COPS) program.  He is the co-creator of the Evidence-Based Policing Matrix, a tool used by local and national organizations including the federal Bureau of Justice Assistance and the National Policing Improvement Agency of the United Kingdom to visualize research results on police effectiveness and translate those results for practitioners and policymakers.  Dr. Koper’s work on the methods of patrolling crime hot spots (often referred to as the “Koper curve” principal) is also used by numerous police agencies in the United States and abroad.
