Research Interests:
Evianne Laetitia van Gijn's doctoral research focused on sex offenders who operate online, and their process of 'grooming' or preparing children for sexual activity. Her doctoral research aimed to contribute to our understanding of the modus operandi of internet child sexual abusers. She examined online conversations of convicted offenders who engaged in online sexual grooming of children in the US and in the UK. She has been fully vetted by police departments to access confidential files at respective serious crime units.
