I have been a PhD student at the Software Modeling and Verification Group (MOVES) headed by Professor Joost-Pieter Katoen since April 2021. Additionally, I am a doctoral researcher within the Research Training Group UnRAVeL.


We cannot avoid POMDPs […] because the real world is one.

Stuart J. Russel, Peter Norvig

My research focus is on the verification of partially observable stochastic models, in particular the analysis of partially observable Markov decision processes (POMDPs). In contrast to classical stochastic models, in partially observable models a decision maker must base its decisions on the available information in a state and not the complete state itself. A special focus of my work is the development of approaches that can be used in practice to verify certain properties on partially observable models.

I am a developer of the probabilistic model checker Storm.
