My main research theme involves explaining observed data, typically resulting from psychological research, with a meaningful and concise model. This task becomes really challenging when multivariate and/or longitudinal measurements are to be modeled jointly. Specific methods of interests concern the development and evaluation of latent variable models (e.g., exploratory factor model), models for test construction (e.g., GAMLSS model for test norming) and data reduction models. Also, I contribute to the improvement of psychological tests and their correct use.
