Research Interests

My research program spans from psychological measurement and psychometrics over machine learning methods to multilevel modeling. I aim at developing new methods in each area and at their intersection, and I also disseminate the newly developed methods to empirical researchers via software contributions in R.

I also teach statistics courses at the Bachelor, Master, and postgraduate level, such as introductory statistics, psychological assessment, computer-based data analysis, structural equation modeling, multilevel modeling, and machine learning methods. I also enjoy to support empirical researchers building up their statistical and psychometric models as a statistical consultant. My teaching and consulting activities also inspire my methodological work.

Equality

I am engaged to foster equality, diversity and inclusion in the psychological research community.

Together with Marie-Ann Sengewald, Pia Bechtloff, and Veit Kubik, I assessed how researchers in psychology are affected from and deal with challenges that arise from care work. We aim at making these challenges more visible via panel discussions and discussion within the research community in Germany, Austria, and Switzerland, and through our report documenting the challenges in our research community:

Eine Bestandsaufnahme zur Vereinbarkeit beruflicher und familiärer Anforderungen im Fachbereich Psychologie mit zielgerichteten Unterstützungsmaßnahmen.
