I am a postdoctoral researcher at the Theory of Hybrid Systems Group headed by Professor Dr. Erika Ábrahám. Currently I am woking in the group  AG Sicherheitskritische Systeme led by Anne Remke in Münster but plan to rejoin THS next year.

My research focuses on reachability analysis for linear hybrid systems based on flowpipe construction. I am developing a C++ library for state set representations in the context of the project Hypro, which is also available at github. Furthermore I am interested in SMT-solving, where I am contributing to the development of SMT-RAT by maintaining the Interval Constraint Propagation (ICP) module.

I am also a complementary researcher in the research training group UnRAVeL working on state set representations for the analysis of hybrid systems.
