Dr. Paul Wiemann

I am a postdoctoral research associate (German: Akademischer Rat a.Z.) at the chair of Statistics at the University of Göttingen, Germany. I hold degrees in Computer Science and Applied Statistics and received my PhD under the supervision of Prof. Dr. Thomas Kneib. Among other projects, I’m working as one of the main developers on the DFG funded software project Liesel (project number 443179956).

I’ve taught Bachelor and Master students at the University of Göttingen and held a tutorial in a summer school. During my time at the TU Dortmund University - as a Step-in Professor in the winter term 2021 - I was responsible for an introductory statistics class for computer science students and also for the class Introductory Case Studies from the data science master program. I have guided and assessed several theses (Bachelor and Master). Please see https://www.uni-goettingen.de/en/470953.html for a list of topics the chair currently offers.
