Dr Jerry Ratcliffe is Professor of Criminal Justice and Director of the Center for Security and Crime Science at Temple University, Philadelphia. He is a former police officer with London’s Metropolitan Police (UK) where he served for several years on patrol duties, in an intelligence and information unit, and as a member of the Diplomatic Protection Group. Due to a winter mountaineering accident while ice climbing in the Scottish Highlands, he left the police service after 11 years. He completed a first class B.Sc. with honors in Geography at the University of Nottingham (UK) and has a Ph.D. from the same institution.

As a lecturer in policing (intelligence) based at the New South Wales Police College he coordinated Australia’s National Strategic Intelligence Course. Dr Ratcliffe also worked as a senior research analyst with the Australian Institute of Criminology, where he conducted one of the first evaluations of an intelligence-led policing operation.

Since moving to the US in 2003, he has worked with numerous agencies and most closely the Philadelphia Police Department. He was the lead researcher on the Philadelphia Foot Patrol Experiment, a citywide study of foot patrol in violent crime hotspots which won awards from the ASC Division of Experimental Criminology and the International Association of Chiefs of Police. He has been a research adviser to the Philadelphia Police Commissioner and the Criminal Investigative Division of the FBI, and he regularly conducts intelligence-led policing training in El Salvador on behalf of the US State Department.

He has twice received the Professional Service Award from the International Association of Law Enforcement Intelligence Analysts (IALEIA), has been awarded the LEIU Distinguished Service Award, and in 2014 he received the Ronald V. Clarke ECCA award for contributions to environmental criminology and crime analysis.

Ratcliffe has published over 80 research articles and five books including ‘Intelligence-Led Policing’ (a second edition was published in 2016), ‘Strategic Thinking in Criminal Intelligence’, ‘GIS and Crime Mapping’ and ‘Policing Illegal Drug Markets’. A co-authored book with Evan Sorg on foot patrol is due out in 2017. He was a member of the National Academies of Science Committee on Proactive Policing and currently sits on the FBI National Academy Advisory Board. In 2015 the US Attorney General appointed him to the Department of Justice’s OJP Science Advisory Board.

In his spare time, he likes to fly (he’s an instrument-rated seaplane pilot), scuba dive, and drink single malt whisky (not at the same time).
