Biography
Greg Ridgeway is the Director of RAND's Safety and Justice Research Program and Director of RAND's Center on Quality Policing, charged with managing RAND's portfolio of work on policing, crime prevention, courts, corrections, and public and occupational safety. Dr. Ridgeway's research involves the analysis of complex datasets in order to address the most pressing policy issues in public safety and justice administration. Dr. Ridgeway recently completed an National Institute of Justice sponsored study of illegal firearm market disruption strategies in Los Angeles, working closely with ATF, LAPD, California DOJ, and the LA City Attorney's office. He is also working with federally appointed monitors in Cincinnati to study police practices and community-police relations and just released an analysis of NYPD records to evaluate racially biased policing in street stops. Dr. Ridgeway has designed and evaluated several randomized and observational studies to measure the impact of policy decisions including a study of illegal firearm interventions in East Los Angeles, the formation of gangs in Pittsburgh, and evaluations of adolescent drug treatment alternatives. His writing on justice topics have appeared in both peer-reviewed journals and in some of the nation's largest daily newspapers. He coauthored a paper presenting a method for assessing racial profiling that was awarded the annual Outstanding Statistical Application award by the American Statistical Association in 2007. Prior to joining RAND Dr. Ridgeway worked on data mining at Microsoft Research, receiving seven patents for developed methods.
