About me
My current research lies at the intersection of group theory and (algebraic) combinatorics. I study symmetries of combinatorial objects using algebraic methods, and combinatorial questions on graphs with an algebraic description, such as Cayley graphs. I am also fascinated by applications of algebra in algorithmic questions.
From 2022 to 2024, I was a postdoctoral researcher in the group of Pascal Schweitzer at TU Darmstadt. From 2019 to 2022, I was a PhD student of Burkhard Külshammer at Friedrich Schiller University Jena. My thesis was in representation theory of finite groups and symmetric algebras.
