I am a researcher at the Department of Statistical Modelling and Artificial Intelligence, Institute of Computer Science of the Czech Academy of Sciences. I am also a member of the COMPS group. My primary area of study is mathematical statistics with a specialization in psychometrics. In my work, I focus on theoretical foundations and computational aspects of psychometrics. The center of my interest is a detailed description of between-group differences with an analysis of so-called differential item functioning. I am also a fan of R programming and development.
