I joined LJMU in 2016, having previously taught criminology and criminal justice at several UK universities and internationally. I also worked as a police officer and with the UK Ministry of Justice. In addition, I have founded, led and advised several international organisations working in criminal justice and with young people.
My primary research interest is 'Justice', focused on four topics:
1. Youth Justice
3. Criminal Justice
4. Innovation and Enterprise
My research approach is empirical, multi-method, interdisciplinary and cross-national.
Current Research Projects (3):
1. 'Youth Justice: Knowledge, Rules and Reality' (external collaboration)
2. 'Privacy and Transnational Criminal Justice' (external collaboration)
3. 'The National Evaluation of The Royal British Legion (TRBL) Breaks Services' (internal and external collaboration)
I am currently:
- Visiting Scholar at the Institute of Criminology, University of Cambridge
- Associate at the African Institute for Crime, Policy and Governance Research
- Chair of Trustees for The Seaver Foundation
- Managing Director at 81 Dots
- Fellow of the Higher Education Academy
I am module leader for level 5 (BA) Decision Making In Criminal Justice, level 6 (BA) Youth Justice, level 7 (MA) Youth Justice and contribute to teaching and research supervision across the undergraduate and postgraduate criminal justice programmes.
I welcome the opportunity to supervise students in criminology and criminal justice, particularly in topics related to my research interests.
