Dr Natalie Mann joined the Policing Institute for the Eastern Region (PIER) as a Principal Investigator in 2017, having previously been a senior lecturer in ARU’s Criminology department, Cambridge. She has conducted extensive research with sexual offenders both in prison and in the community and now specialises in the management of sexual offenders.

She has worked extensively with Police and National Probation Service practitioners in the field of public protection and has very recently completed a two year national evaluation of the Active Risk Management System (ARMS), a risk management tool used with registered sexual offenders in England and Wales, by Police and the National Probation Service. This evaluation was requested by the National Police Chief’s Council lead for MOSOVO (management of sexual offenders and violent offenders) and it was fully supported by the Ministry of Justice and Her Majesty’s Prisons and Probation Service.

Natalie is currently leading a two year research project which examines the effectiveness of MAPPA (Multi-agency public protection arrangements) and how the integration of academic, practitioner and offender knowledge can help to deliver excellence in the multi-agency risk management of violent and sexual offenders in the community.

Alongside front line research in public protection and sexual offender management, Natalie works extensively with criminal justice practitioners, charities, non-government agencies and technology companies to facilitate PIER’s key role in knowledge exchange, the sharing of best practice and innovation in policing practice, via the design and delivery of regular CPD sessions for police practitioners working within the field of child sexual abuse and exploitation, and the management of sexual offenders.
