Professor of Mathematics at the University of Duisburg-Essen (Germany). My research is on arithmetic geometry.

So far, I have used Numbas mainly for my Linear Algebra classes (winter 2020/21, summer 2021). In the forthcoming winter 2024/25 term I will teach Mathematics for Economists and I intend to create Numbas problems for this class.
