This is a spherical Coxeter comlex of type A_3. This picture was designed with the beautiful program GeoGebra.


This term I give the RTG lecture Coxeter groups and buildings. If you are interested in the material, I am happy to share my notes, exercises and GeoGebra files. Just send me an email.

Mathematical Interests

Geometric and topological group theory, algebraic combinatorics,
group actions on discrete structures, properties of these groups and structures, (right-angled) Coxeter groups, buildings, non-crossing partitions

Dissertation: Structural properties of non-crossing partitions from algebraic and geometric perspectives


This term I am organizing various events. Come by and join us!

With the Equal-Opportunities Team and the group Women in Math we are organizing a regular Lunchmeeting in Math. All students are cordially invited to join!

The Atrium Evening takes place on July 6th and gives the opportunity to get to know the career path of two women in mathematics.

The RTG conference Diverse Aspects of Groups, Geometry and Dynamics takes place from September 18th to 20th at Heidelberg University.
