Lecturer in Criminology and Social Policy, University of Sheffield

Xavier joined the department as a Lecturer in Criminology and Social Policy in September 2015 having previously worked at the department between 2012 and 2014. Previous to this, he completed his undergraduate law degree at Durham University in 2006. During these studies, Xavier's interests moved towards the sociology of deviance and the criminal justice system. As a result, following his undergraduate studies Xavier undertook an MA in Criminology at the University of Leeds. He subsequently completed a PhD in Criminology at Teesside University.

Xavier's doctoral thesis concerned law enforcement and government definitions of organised crime and the impact upon contemporary police measures. As part of this research, Xavier carried out an ethnographic case study of an active tobacco smuggling enterprise. He subsequently worked as a research associate at the Universities of Sheffield and Leeds on international and domestic research projects concerning surveillance and policing.

He is currently actively conducting research in the areas of organised crime, policing and surveillance and welcomes enquiries on these themes.
