Welcome
… to my website. I am a Professor of Statistics at the University of Bonn.

I pursue an application oriented research approach focusing on actual real data problems that are both statistically interesting and practically relevant. Starting points of my past and current research are data challenges in (energy) economics, finance, e-commerce (e.g., Google AdWords data), emotion psychology, biomechanics, and human movement sciences.

My current methodological and theoretical research interests focus on functional data analysis, nonparametric statistics, longitudinal data analysis, simultaneous inference, and statistical fairness. Last but not least, I am committed to providing the computational implementations of my statistical research and publish R-packages at CRAN and GitHub accompanying my research papers.
