Onderzoek / Research

My PhD research project under supervision of Prof. Dr. Rossi, is concerned with the sequential analysis of the offender-victim interaction in violent sexual assaults and the influence of situational variables on the offender's behaviour. I use a novel technique to capture the dynamics of rape, the proximity coefficient (P) that has been developed and already applied to various areas by Prof. Dr. Paul Taylor who is heading the Security Lancaster centre at Lancaster University. The central idea is that offender behaviour is much more determined by situational and contextual influences than traditional approaches to differentiate offenders have previously acknowledged. Thus, we argue that a more detailed look at the unfolding offending process will offer valuable insights into the outcome of the event and about the offender. We are very lucky to collaborate with the ViCLAS section of the Federal Belgian Police and the Serious Crime Analysis Section of the National Crime Agency (NCA) in the UK.
For more information on the proximity coefficient (P) please visit Paul's website. We are also examining the potential benefits of sequential analysis for comparative case analysis and suspect prioritisation.

I am also currently involved in the unique Crime Linkage International Network (C-LINK). C-LINK is an international group of crime linkage researchers and practioners collaborate to establish a coherent, evidence-based approach to the detection of serial offenders using crime linkage techniques. Please check out the C-LINK website for more detailed information on the network, projects and crime linkage resources.
