Dr Clifford Stott

Principal Research Fellow in Security and Justice

I am the Principal Research Fellow for the Security and Justice Research Group, an inter-disciplinary research cluster within the University of Leeds ‘Building Sustainable Societies’ Project. I specialize in understanding crowds, ‘riots’, ‘hooliganism’ and public order policing. I graduated from the School of Psychology at the University of Exeter with a PhD in Social Psychology and have held Lectureships and Senior Lectureships at the Universities of Bath, Abertay Dundee and Liverpool. Between 2008 and 2013 I was a Visiting Professor at the Institute of Sports Science Aarhus University in Demark and am currently a Visiting Professor at the Socio-Technical Centre until late 2015. I have also held Visiting Fellowships and Scholarships at the Australian National University, the University of Exeter and Flinders University.

My research work centres on crowd psychology, ‘riots’, football ‘hooliganism’ and public order policing and focuses theoretically on the role of intergroup and social identity processes in collective violence. I have a general interest in the contribution that Self Categorisation Theory can make toward our theoretical understanding of security issues. My work has achieved high-level policy impacts globally. In the last ten years my research has informed policy for the U.K. Home Office, the Association of Chief Police Officers, the College of Policing, the European Council, the European Union, the Portuguese, Swedish and Danish Police and the Union of European Football Associations (UEFA). My research forms the conceptual basis of public order police policy and training in the UK as it has done for over a decade in other areas of Europe. Whilst this impact is latterly focused on the management of collective conflict during protests my research has also underpinned the security policy for major international football Championships in Europe. In 2014 was awarded first prize in the Public Policy category of the Economic and Social Research Council’s ‘Celebrating Impact’ awards.

I have been involved in research and consultancy projects worth well in excess of £1.5 million, most recently on an ESRC Knowledge Exchange project in collaboration with West Yorkshire Police and the Office of the Police and Crime Commissioner. I am on the Editorial Board of Criminology and Criminal Justice, which is the Journal of the British Society of Criminology. I am also an Editorial Consultant for the British Journal of Social Psychology. I have previously been a Consultant Editor for the European Journal of Social Psychology and a Guest Editor of Contemporary Social Science, which is the Journal of the Academy of the Social Sciences. I have an extensive media portfolio appearing with Andrew Marr on the BBC Documentary ‘Britain from Above’ discussing policing in football; with Michael Portillo in the BBC science programme ‘Horizon’ replicating Milgram’s infamous ‘Obedience Paradigm’; and with Tom Dyckhoff in the Channel 4 documentary series ‘The Secret Life of Buildings’ discussing stadium architecture. I regularly appear in press articles and on radio and television nationally and internationally speaking about my research and its relevance to contemporary social and political issues.

Research Interests

I completed my PhD on the Intergroup Dynamics of Crowd Psychology under the supervision of Professor Stephen Reicher (University of St Andrews). This research played an important role in developing the Elaborated Social Identity Model of crowd behaviour (ESIM), which is an application of Self Categorisation Theory to crowd action. The ESIM is now widely acknowledged as the leading social psychological theory of crowd psychology, particularly as this relates to our theoretical understanding ‘rioting’. My early post-doctorate career focused on understanding the crowd dynamics of football ‘hooliganism’ particularly the ‘rioting’ involving English fans travelling into Continental Europe. In the past decade my career focus has been on extending these important theoretical developments toward an applied and impact agenda, primarily through integrating ESIM analyses of rioting into professional policy and practice among police forces globally. More recently, I have moved away from the increasingly narrow confines of Psychology toward the interdisciplinary environment of Criminology where I have been focused upon developing research within the broad agenda of security and justice. I have published over 50 articles in leading interdisciplinary peer reviewed journals and co-authored and edited three books: ‘Football Hooliganism, Policing and the War on the ‘English Disease’’ co-authored with Dr Geoff Pearson (University of Liverpool); ‘Mad Mobs and Englishmen: Myths and Realities of the 2011 riots’ co-authored with Professor Steve Reicher; ‘The Crowd in the 21st Century’ co-edited with Dr John Drury (University of Sussex).

Recent Research Projects
  • N8 Policing Research Partnership. Co-investigator on a £50,000.00 project funded by the College of Policing Innovation Fund within which I was the project co-lead on Public Order Policing.
  • ESRC funded Knowledge Exchange Partnership with the OPCC West Yorkshire and West Yorkshire Police. I am the project lead for the Public Order strand which involves a series of field based observations, training and dissemination event.   


I am currently programme manager for the MA Security and Justice and module manager for its core module LAW5300M ‘Security and Justice’. Beyond this I have wide-ranging experience in undergraduate and postgraduate teaching and supervision. I also have extensive experience of developing and delivering training courses for police commanders involved in policing crowd events. I teach regularly and have lectured at Police Academies across the globe.


I undertake a range of consultancy work. Recent projects include acting as the Educational Director of the Pan European Football Policing Project between 2010 and 2012. In 2014 I was a peer reviewer to ACC Geoff Dodd (WYP) who was the Gold Commander of Operation Woolfox surrounding the EDL demonstration in Batley. I provided the academic scrutiny review for the ACPO working paper on policing linked to on-shore oil and gas operations. I also provided academic scrutiny for the report ‘Making and Breaking Barriers: Assessing the value of mounted police units in the UK’ part funded by the ACPO Mounted Working Group.  

PhD Supervision

I am able to supervise PhDs and MA (Research) in the following general areas:

  • Crowds, riots and collective conflict.
  • Policing: particularly in the area of ‘public order’.
  • Hooliganism and football related ‘disorder’.
  • Procedural justice, legitimacy and social identity.
