About me

I am a statistician currently working as a Junior Research Group Leader for Bayesian Statistics at the Cluster of Excellence SimTech, University of Stuttgart. I am interested in a wide range of research topics most of which involve the development, evaluation, implementation, or application of Bayesian methods. See here for an overview of my scientific publications. You can also find me on GoogleScholar. I am deeply involved in open source software development and you can find my major contributions below. Originally, I have studied Psychology and Mathematics at the Universities of Münster and Hagen and did my PhD in Münster on Optimal Design and Bayesian Data Analysis. Before starting my own research group in Stuttgart, I have worked as a postdoctoral researcher at the Department of Computer Science, Aalto University.
