I am a professor in computer science at Saarland University. I am currently the chairman of the examination board. If you have questions regarding the examination regulations please come to my office hours on Wednesdays 3-4pm.
I am co-chair of the program committee of ATVA 2015, member of the program committees of RV 2016 and SYNT 2016, and member of the editorial board of Acta Informatica.
I am interested in computer systems and protocols that are reactive in nature: systems of concurrent processes that interact with each other and with their environment over a possibly infinite run. Parallelism and nondeterminism make it difficult to design such systems correctly. My research concerns computer-aided methods that derive implementations from formal specifications (synthesis) and that prove that a given implementation satisfies a logical property (verification).
