Jeffrey Fagan is a leading expert in policing, crime, gun control and race whose scientific research has an impact on public policy.

A prolific scholar, Fagan has served on the editorial boards of scientific journals, provided expert testimony, and is a sought-after commentator on policing, race, and the death penalty. His work includes research on the death penalty; the legal socialization of young people; Neighborhoods and crime; and juvenile delinquency and punishment. Fagan's research into the New York Police Department's stop-and-frisk practices - which found that more than 30 percent of the stops were legally unjustified or questionable - was central to a 2013 federal court ruling that found the policy unconstitutional .

Fagan, who has taught at Columbia Law since 2001, is also professor of epidemiology at the Mailman School of Public Health and was visiting professor at Yale Law School. He has received awards and grants from institutions such as the Russell Sage Foundation, the Robert Wood Johnson Foundation, and the Soros Justice Fellowship of the Open Society Institute. He is a member of the editorial boards of several criminology and law journals and was the past editor of Journal of crime and crime research.

Fagan served on the Law and Justice Committee of the National Academies of Science and the 2004 National Research Council that examined policing in the United States. He was a member of the Research Network on Adolescent Development and Juvenile Justice of the MacArthur Foundation and a founding member of the National Consortium on Violence Research. He was an expert on the death penalty for the UN Office of the High Commissioner for Human Rights. He is a fellow of the American Society of Criminology and served on the board for three years.

In Columbia, Fagan directed the Law School's Center for Crime, Community, and Law and served on the Steering Committee of the Columbia Center for Youth Violence Prevention at the Mailman School of Public Health.
