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
Current Research Projects (3):
1. Youth Justice: Knowledge, Rules and Reality (external collaboration)
2. The Sex Offender Register: Politics, Policy and Public Opinion (external collaboration)
3. Japanese Juvenile Justice (external collaboration)
4. Enterprising Students: A Values-Driven, Competency-based Framework for Embedding Enterprise in the HE Curriculum (internal collaboration)
I am currently:
- Visiting Scholar, Institute of Criminology, University of Cambridge
- Associate, African Institute for Crime, Policy and Governance Research
- Chair of Trustees, The Seaver Foundation
- Fellow, Higher Education Academy
- Associate, Enterprise Educators UK
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.
