Professor Graham Farrell

Professor of International and Comparative Criminology

I joined the School of Law in 2015, having previously been professor at Simon Fraser University in Canada and before that professor at Loughborough University.

I have also worked in the United States as deputy research director of the Police Foundation in Washington DC, at Rutgers University and the University of Cincinnati.

In the 1990s, I worked at the United Nations in Vienna and, before that, at the Centre for Criminological Research at the University of Oxford. My PhD is from the University of Manchester (1994) and BSc from the University of Surrey.

Research Interests

My broad research interest is in Crime Science, particularly situational crime prevention – designing-out and nudging people away from crime. This spans a wide range of areas but, in recent years, much of my research examines why crime has been declining in many countries – the ‘crime drop’. This has involved, with colleagues, developing the security hypothesis and examining the role of security improvements in declining crime as well as scrutinising ‘rival’ explanations.

But I am also interested in the application of situational prevention to other types of crime. Most recently, this has included work on mobile phone theft and robbery, as well as student academic misconduct. My main theoretical interests, which underpin most of my work, relate to rational choice theory and routine activity theory.

I have been awarded research grants from various sources including the Economic and Social Research Council, the Engineering and Physical Sciences Research Council, the European Union, and the Social Sciences and Humanities Research Council (Canada).

Over the years, I have published a range of studies on aspects of international drug trafficking and drug policy. In 2007, I conducted fieldwork in Afghanistan (mainly Kabul) to evaluate criminal justice system projects undertaken by the United Nations Office on Drugs and Crime. I have researched a number of other areas relating to crime, policing and criminal justice. My doctoral research was on repeat victimisation and I continue this interest, particularly as it relates to situational crime prevention.
