Associate Professor

About Me

I work at the University of Twente, Faculty of Behavioral, Management, and Social Sciences, in the Department of Research Methodology, Measurement and Data Analysis. My research activities cover different areas in Bayesian item response modeling and the development of Bayesian statistical methods for clinical data and randomized clinical trials.

Main interest is focused on complex latent variable modeling in higher-dimensional problems. The areas of modeling research relate to theory and methods of multivariate analysis, stochastic simulation, mixed effects modeling, among other things. Applications and data analyses are executed in the field of educational, medical, and psychological research.

I am working on the development and application of Bayesian response models for large-scale comparative survey research. In various publications the Bayesian modeling approach is proposed that addresses well-known methodological issues, as they arise in large-scale comparative survey research.
