About Me

I am a full professor of Cyber Security and Business Continuity at the University of Twente. I started my career at the Research and Documentation Centre (WODC) of the Ministry of Justice in 1981. I worked as a Senior Researcher at the Netherlands Institute for the Study of Criminality and Law Enforcement (NSCR – in Leiden) (1992-2000) and as an Associate professor at the Department Developmental Psychology - Utrecht University (2002-2008). I am a member of the Scientific Advisory Council (WAR) of the Dutch Defense Academy.  I founded the Crime Science journal together with Pieter Hartel and was an associate-editor for 6 years (https://crimesciencejournal.springeropen.com/).

My research interests are in the field of (online) crime, fraud and aggression and various forms of (online) fraud risk behavior. My aim is to improve prevention and provide tools for law enforcement. Together with colleagues I work to develop interventions that will help to protect users against social engineering, crime victimization and to increase compliance. 

My present research investigates the human factors of fraud and of cybercrime, more specifically in victimization, fraud, online disclosure and privacy issues. Why do users trust phishing emails or fraudsters?  Why do they comply or not comply to safety rules, why do they disclose so easily personal information and how can they be helped to become more vigilant users in order to protect themselves?
