About me

I am a Ph.D. statistician currently working at the University of Münster (Germany), Department of Psychology. I am the author of the R package brms and member of the Stan Development Team. Previously, I have studied Psychology and Mathematics at the universities of Münster and Hagen. See here for an overview of my scientific publications.
