Why are some teenagers delinquent? How do we know whether an adolescent is grumpy or depressed? Which parenting practices promote adolescent well-being, and future positive development? Hoe does this parenting process differ from child to child?

With my research, funded by the Dutch Scientific Organisation (NWO-VIDI) and in collaboration with Savannah Boele, we attempt to answer questions like these, regarding normal and deviant development. We combine large questionnaire studies with micro-questionniares on smart phones, and employ advanced statistics to unravel the underlying driving processes of real-life development. 

Together with Angelique Cramer, we have set up the Tilburg Experience Sampling Center. This center facilitates research on the real-time dynamics of mental health and well-being, using smart phones and wearables.
