I gained a Diplom degree in Computer Science (Diplom Informatiker) with a minor in Operations Research and Planning in 1997 from the University of the Federal Armed Forces Munich. Then I worked in the Command and Control Systems Command of the German Navy as a Systems Engineer in different fields of the analysis and construction of safety-critical systems, including the specification and construction of such systems as well as quality assurance and project management. To complement this, I gave myself a treat and studied Math at the FernUniversität in Hagen, earning a degree in Mathematics (Diplom Mathematiker) in 2004. Returning to education, I joined the Reactive Systems Group at the Department of Computer Science of Saarland University in 2004, and obtained a PhD (Dr. rer. nat.) in Computer Science in 2008. I was appointed Lecturer in the Department of Computer Science at the University of Liverpool in September 2008.

I am interested in automata and game theory and its applications in the construction and analysis of safety-critical systems. This includes constructions and decision procedures for automata over infinite words and trees and games with infinite duration, as well as algorithms and tools for the automated verification and synthesis of reactive systems. My research concerns reactive computer systems and protocols: systems of concurrent processes that interact with each other and with their environment over a possibly infinite run. This family of systems contains many safety-critical applications like air traffic control systems, communication controllers in automotive systems, and security protocols. Parallelism and non-determinism make it difficult to design such systems correctly. I study automated methods that prove that an implementation satisfies a logical property (verification) and that derive implementations from logical specifications (synthesis).
