Arnt Schellekens has been working as a psychiatrist at Radboudumc since 2012 and has been appointed as full professor addiction and psychiatry at Radboud University/Radboudumc in 2020. Moreover, he is researcher at Donders Institute for Brain, Cognition and Behavior. He became Scientific Director of the Nijmegen Institute for Scientist Practitioners in Addiction (NISPA) in 2015.

First, to better understand basic neurobiological and behavioral mechanisms underlying these disorders. Second, to use these insights to explain the impressive co-morbidity of addiction and stress-related psychiatric disorders (e.g. ADHD & depression). Third, to develop new innovative strategies to treat these disorders. Arnt Schellekens created translational and multidisciplinary collaborations between the Nijmegen Institute for Scientist Practitioners (NISPA), the Radboud University Medical Centre, behavioral scientists from the Behavioral Science lnstitute (BSl) and neuroscience colleagues at the Donders Institute for Brain, Cognition and Behaviour, in order to reach his research aims.
