Patricia Martinkova
I am senior researcher, the head of the Department of Statistical Modelling, Institute of Computer Science of the Czech Academy of Sciences, and the leader the Computational Psychometrics Group. I am also an Associate Professor at Faculty of Education Charles University, where I initiated the Center for Educational Measurement and Psychometrics with 2018–2020 PRIMUS project. I am Fulbright alumna and 2013-2015 visiting research scholar with the University of Washington, and an affiliate at UW Center for Statistics and the Social Sciences and at UW Department of Statistics.
My research focuses on developing models and estimators to improve the quality of ratings and measurement in various fields, including education, psychology, and health. I use simulation studies to demonstrate better properties and advantages of newly developed methods and estimators over those traditionally used in daily praxis.
I am big fan of reproducible research and freely available software. Part of my research is exploited in interactive online application ShinyItemAnalysis, which is now being used in many research fields all around the world.
My teaching interests cover various topics of applied statistics and psychometrics. I teach course NMST570 Statistical methods in psychometrics and NMST571 Seminar in Psychometrics. I am interested in incorporating active learning techniques into teaching.
