The way we think and approach life distinguishes who we are and what we accomplish in life. Optimism, determination, helpfulness and sincerity are qualities that characterise me. In recent years I developed myself as a teacher and researcher, whereby I managed groups and projects and extended my knowledge about criminal law, psychology and research methods. Currently I am working on my PhD project about online sex offending and grooming. 


My first chapter publication is now published:

In my first article (currently under review), we used a qualitative thematic analysis to analyse 195 cases of chat conversations between online groomers and operators posing as a minor Filipino girl, to investigate online groomers' approaches to entice minors for sexual activities.

In the Master Clinical Forensic Psychology, I supervise 7 students with their master's thesis.
