I am a PhD fellow at
Department of Statistical Modellling,
Institute of Computer Science of the
Czech Academy of Sciences and at
Department of Probability and Mathematical Statistics,
Faculty of Mathematics and Physics,
My current research focuses on statistical models in psychometrics covering differential item functioning, estimation of item properties, and latent variable models, especially value added models. I am interested in R programming and development.
