Research interests

I am a research psychologist with a background in clinical, developmental and biological/neuro psychology. The focus of my research is on the causes and consequences of ADHD, aggression, and tics/OCD in children and adolescents. Topics of my interest are cognition, biomarkers, stress physiology, gene-environment associations, early adversities (pre- and perinatal, stress, family and social context), as well as predictors of treatment success. 

Projects

• Social cognition in adolescents with disruptive disorders and aggression, an EEG study (SCODA)
• Social cognition in adolescents with autism spectrum disorders (SCASS), an EEG study. Collaboration with EU-AIMS/LEAP. (SCASS)
• Methylphenidate discontinuation studies and audit (MASK, PROEFSTOP, MEDUSA). Risperidone discontinuation study and audit (ORKA).  
• DREAMS: Dutch Research in Child and Adolescent Mental Health Study. An initiative of the four major Dutch centers Accare, Curium, Karakter and Levvel to improve child and adolescent mental health. Focus: 1. predictors treatment success, 2. neuropsychology. (DREAMS)
