Michael BrownMichael Brown OBE

Chief Inspector


Michael is the mental health coordinator for the National Police Chiefs’ Council and the College of Policing – a serving officer with West Midlands Police for 20 years. His work in the UK has prevented tens of thousands of vulnerable people being detained in police custody whilst in crisis and secured the prosecution of many vulnerable offenders who pose a serious risk of harm to the public. 

His blog on policing and mental health has been used millions of times across the world and used as the basis for national guidelines for the police service in England and Wales. He was singled out for mention and commendation by the Home Affairs Committee of the UK Parliament after giving evidence to their inquiry into policing and mental health and has advised the British Government on reform of mental health laws affecting the police.  Michael was the recipient of the President’s Medal from the Royal College of Psychiatrists for his “significant contribution to improving the lives of people with mental illness”. In 2016 he was appointed an OBE in Queen Elizabeth’s 90th Birthday Honours for his services to policing and mental health.

Rob HeatonRob Heaton 




Rob Heaton is a Senior Visiting Research Fellow at Canterbury Christ Church University. During a 30 year career in Kent Police, he attended the first MSc (Criminal Justice) course at the University of Portsmouth. During this time, he became interested in the interaction between policing theory and practice, in particular the connection between methods of policing and crime rates. Rob’s (2007) PhD subject was based around this subject, about which he has produced a number of papers and shorter articles. He has also written further about subjects of interest such as workload and risk in operational policing. Rob currently teaches on Masters degree courses at CCCU and is involved in a number of research projects.


simon-holdaway-120x120Simon Holdaway



Simon left school aged 16 with minimal qualifications. He joined the Metropolitan Police Cadet Force and served subsequently as a constable and, then, sergeant, for eleven years. During his service he was seconded to Lancaster University for undergraduate study, returning to his force with a first class honours degree, promotion to Sergeant and registration as a part-time PhD student at LSE.

Simon’s doctorate was the first ever covert, empirical study of policing in the UK. He documented uniquely what has become a ‘common-sense term’ within policing – police culture - and, rather differently, a concept fundamental to academic research about the police.

In 1975 Simon was appointed Lecturer in Sociology at Sheffield University and subsequently became Professor of Criminology and Sociology and moved to Sheffield’s School of Law as Director of its world-renown Centre for Criminological Studies. In 2004 he was elected a Fellow of the Academy of Social Sciences. During his last years at Sheffield he was Head of the School of Law.

Apart from his research about police culture he has also written books and many academic papers about aspects of race relations within constabularies. His work has informed national policies; public inquires into policing; key industrial tribunal cases involving minority ethnic officers; the work of Black Police Associations across the UK; and police forces in Europe and North American.
