The police are chronically a topic of heated debate. However, most statistical analyses brought to bear on questions of police fairness rarely provide clarity on or solutions to the problems. This talk will cover statistical methods for estimating racial bias in traffic stops, identifying problematic cops, and determining which officers are most at risk for police shootings. All of these methods have been part of investigations of police departments in Oakland, Cincinnati, and New York and show that statistics has an important role in prominent crime and justice policy questions.

Greg Ridgeway is Associate Professor of Criminology and Statistics at the University of Pennsylvania. Prof. Ridgeway’s research involves the development and application of statistical methodologies for answering questions about crime and the criminal justice system, including guns, drugs, policing, and fairness in the justice system. He is currently working with US DOJ Civil Rights Division on cases involving Maricopa County (AZ) Sheriff and Baltimore PD and with the Illinois Attorney General on the Chicago PD case. Previously Prof. Ridgeway directed the National Institute of Justice, the US Justice Department’s science agency, managing a staff of 80 employees and a budget of $250M with a mission to improve the justice system by advancing research in social, physical, and forensic sciences. Prior to joining the Department of Justice, Prof. Ridgeway directed RAND's Safety and Justice Research Program. Prof. Ridgeway is a Fellow of the American Statistical Association and an inventor on eight patents, the most recent granted in 2014 and a ninth filed in 2017. He received a PhD in statistics in 1999 from the University of Washington, Seattle.
