Assistant Professor
Expertise
My research focuses on the analysis of intensive longitudinal data, with the aim of improving how we model dynamic psychological processes. In particular, I develop statistical models that capture meaningful individual differences in such data. For instance, I create clustering approaches tailored to intensive longitudinal data, allowing for the identification of more homogeneous subgroups of individuals and thus more precise insights.

I am also committed to translating novel statistical methodologies into freely accessible software, enabling transparent, reproducible research and immediate practical application. The code to estimate the statistical models developed in my research is openly available on the Open Science Framework and GitHub (links below).

Professor of Multivariate data analysis
Expertise
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 and test norming. Also, I contribute to the improvement of psychological tests and their correct use.
