I am a PhD student at the Software Modeling and Verification Group (MOVES) headed by Professor J.-P. Katoen.
My research interests include:

Formal methods for qualitative and quantitative systems
Deductive reasoning methods for quantitative systems
Formal semantics of high level specification languages
