Criminologist Jeffrey A. Fagan’s research focuses on policing, the legitimacy of criminal law, capital punishment, and juvenile justice.

He served as an expert witness in the U.S. Department of Justice’s investigation into the shooting of Michael Brown, which concluded that the police department in Ferguson, Missouri, had a “pattern or practice” of unconstitutional conduct. In a previous case, his analyses showing that New York City’s stop-and-frisk policy disproportionately impacted blacks and Hispanics contributed to a federal judge’s ruling that the practice was unconstitutional.

Fagan is a past recipient of the Power of One Racial Justice Award from John Jay College of Criminal Justice. He has served on the research advisory board of the Innocence Project, the Committee on Law and Justice of the National Academy of Science, the MacArthur Foundation’s Research Network on Adolescent Development and Juvenile Justice, and as an expert witness for the U.N. Office of the High Commissioner for Human Rights.
