Dr. Marleen Weulen Kranenbarg is assistant professor in Criminology at the School of Criminology of the Vrije Universiteit (VU) Amsterdam. In 2018 she completed her dissertation research entitled: ‘Cyber offenders versus traditional offenders: an empirical comparison’ at the NSCR (Netherlands Institute for the study of Crime and Law Enforcement). Her current research focuses mainly on three themes within cybercriminology: 1. Differences with traditional crime, 2. The role of online and offline peers, and 3. Ethical hacking and positive use of IT skills. For this third research line she recently received a prestigious personal VENI grant from NWO (Netherlands Organization for Scientific Research) for a 5-year research project entitled ‘Choosing the good side: life-course, cultural, and situational factors that lead to non-criminal hacking.’
