Biography

I am an assistant lecturer at the Lancaster University Leipzig (LUL).

I was an (interim) associate professor at the Technical University Munich (TUM) at the Campus Heilbronn during the summer semester 2023. Before that, I was Post-Doc at the Institute of Science and Technology Austria (ISTA) / Chatterjee group (2022-2023). I defended my PhD (with distinction) at the Technical University Munich (TUM) under Jan Křetínský (2017-2022). I obtained Masters’ degrees in Math and Computer Science at TUM (both with distinction).

Research

My main research interest is the formal verification of (finite state) probabilistic systems. Currently, I particularly seek to establish a broader recognition for notions of risk in such systems and usage of risk-aware verification.

Aside from that, I contribute to LTL-to-automaton translation, machine learning in verification, complexity theory, and game theory (bidding games & multi agent systems).
