As a senior researcher and clinical neuropsychologist I work at Jellinek TOPGGz in Amsterdam, Jacob Obrechtstraat. I am also a lecturer in clinical neuropsychology at the University of Amsterdam. I obtained a PhD on the neuropsychological effects of ecstasy (2009). Within the Academic Workplace Addiction of Arkin/Jellinek I am active within the research line ‘Innovations in healthcare and healthcare research‘, where I mainly focus on neuropsychological aspects of addiction and substance use.
