### About

I’m a postdoctoral researcher in the group of Simon Brandhorst at Saarland University, supported by SFB-TRR 195. My main research focus lies in algebraic number theory, in particular from an algorithmic point of view, and computer algebra in general. Among other things, I work on the following topics:

- Computation of class groups of number fields.
- Construction and tabulation of number fields.
- Algorithmic methods for Galois module theory.
- The conjugacy problem in arithmetic groups.
- Computation of Gröbner bases.

For a complete picture, have a look at my publications. As part of my research, I am implementing algorithms and developing computer algebra software, see software.
