Research Activities

In the context of the DFG-project TypicalCPA – Typical Worst Case Compositional Performance AnalysisI look into the formal timing analysis of embedded systems with weakly-hard real-time constraints.

Moreover, I am interested in methods which serve to systematically analyse the behavior of computing systems and communication networks in case of failure.
