Prof. Dr. Christian Weiß

Prof. Dr. phil. nat. 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 Frankfurt University, 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 faculty.

Research Interests

- 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
