Prof. Dr. habil. Christian Weiß
In 2012, Christian finished his PhD thesis on “Twisted Teichmüller curves”. His advisors were Martin Möller, Goethe-University Frankfurt, and Don Zagier, Max-Planck Insitute for Mathemtics Bonn. After a short period as postdoc at Goethe-University Frankfurt, he moved to the financial industry working as an actuary in risk management. In 2017, he got a professorship for mathematics at Ruhr West University of Applied Sciences. One year later he became dean of his faculty. In 2022, Christian completed his habilitation on "Number Theoretic, Dynamical and Geometric Contributions to Equidistribution Theory" at Würzburg University. The members of his habilitation committee were Jörn Steuding (Würzburg University), Christoph Aistleitner (Technical University Graz) and Jürgen Sander (Hildesheim University).
- Algebraic number theory
- Quasi-Monte Carlo methods and their application in financial mathematics
- Dynamical Systems, in particular interval exchange transformations
- Discrete groups, in particular Fuchsian groups
