About me

I am professor (‘adjunct hoogleraar’) in Applied Statistics and Data Visualisation. I’m part of the Psychometrics and Statistics group at the Faculty of Behavioural and Social Sciences of the University of Groningen.

One of my main research lines concern psychological dynamic models. In order to properly understand the processes behind human behaviour, observations at one single time point are inadequate. Research designs with intensive measurements across time for individual subjects can help to answer research questions for which ‘classical’ designs were not equipped. Although the merits of the principles underlying time series analysis have been shown convincingly in psychology, further technical improvements are necessary. I develop such models and apply them to behavioural data from different contexts, with emphasis on clinical and environmental psychology. For details, see here.

It is important to inform the general public about the work that scientists do. Statistical communication in particular has my interest. I write columns (mostly in Dutch) for various outlets, including national newspaper De Volkskrant and local university newspaper UKrant.

I am president of the Netherlands Society for Statistics and OR (VVS-OR), research director of the Heymans Institute for Psychological Research, secretary of the Groningen University Fund, and elected member of the International Statistical Institute.
