Since February 2025, I am Professor in the Department of Computer Science at the University of Kaiserslautern-Landau (RPTU), where I head the Automata and Complexity group. Before that I was a postdoc and a research group leader at the Max Planck Institute for Software Systems (MPI-SWS) in Kaiserslautern, Germany. Between Oct 2023 and Mar 2024, I held an Interim Professorship for Theoretical Computer Science at Leipzig University. In Oct 2019, I obtained a PhD with Markus Lohrey at the University of Siegen.

My research interests include automata theory, logic in computer science, verification of infinite-state systems, algorithms on compressed data, as well as algorithmic group theory.
