I am a PHD student in the DFG research training group Experimental and constructive algebra. My supervisor is Prof. Dr. Gerhard Hiss.

Research
I am currently working on the representation theory of Coxeter groups and Iwahori-Hecke algebras. In particular I am interested in the structure of modules obtained via induction from parabolic subalgebras. I am also studying analogous questions for complex reflection groups and their Hecke algebras. Finally, I am interested in computational questions such as the computation of decomposition numbers of Iwahori-Hecke algebras in bad characteristic.

    • Thesis
    In 2016 I finished my master thesis Representations of Iwahori-Hecke Algebras Induced from Parabolic Subalgebras under the supervision of Prof. Dr. Gerhard Hiß. Note that the explicit main results of chapters 3 and 4 are just special cases of the far more general result in Induced Modules of Split Iwahori-Hecke Algebras are Reducible, see Publications.
