Center on Terrorism

Welcome to the Center on Terrorism at John Jay College of Criminal Justice

John Jay College lost 67 students and alumni as a result of the terrorist attacks on the World Trade Center in lower Manhattan on September 11, 2001. The Center on Terrorism at John Jay College was founded in the wake of those attacks and remains the only university-based entity devoted to terrorism research and education in the New York City area. Center researchers have published a range of books, article, chapters and reports covering different aspects of terrorism and counter-terrorism, from an interdisciplinary and policy-relevant perspective. The Center hosts the Friday Seminar Series which brings to the John Jay campus leading researchers and practitioners active in the field. The series is linked to John Jay’s Advanced Certificate in Terrorism Studies which offers a distinctive graduate-level program of study for those seeking to enhance their credentials and better understand terrorism and counter-terrorism. 

We look forward to seeing you soon.
