Wim Bernasco studied social psychology at Leiden University, and obtained a Ph D in sociology at Utrecht University. His Ph D thesis explored the interrelated nature of the occupational careers of spouses. Before joining the NSCR in 2000, he worked in different positions at various universities and at the research center of the Ministry of Justice. His current work focuses on spatial aspects of criminal activities, a broad area that encompasses a number of research questions. What drives variation in crime and delinquency between neighborhoods? Which effects do physical and social barriers have on offender travel behavior? How do offenders search and select their targets and methods? Do they offend in the communities where they used to live? Is crime spatially displaced when criminal opportunities are blocked? What causes repeat victimization? Does the risk of criminal victimization communicate spatially, and why? Wim explores many of these themes in collaboration with researchers from the United Kingdom, Australia and the United States. His recent international publications appear in Criminology, Journal of Quantitative Criminology, British Journal of Criminology, European Journal of Criminology, Crime Psychology & Law, and Journal of Investigate Psychology and Offender Profiling.
