Short CV: I am a Professor for Computer Networks and Distributed Systems at the Technical University of Dortmund. I received my PhD degree in Computer Science from ETH Zurich, supervised by Roger Wattenhofer in the Distributed Computing Group, supported by Microsoft Research. Afterwards, I was a visiting researcher at Microsoft Research, Redmond, USA, working with Ratul Mahajan. As a postdoc, I was fortunate to work with Stefan Schmid at Aalborg University, Denmark, and at the University of Vienna, Austria. I also have diplomas in Mathematics and Computer Science from TU Braunschweig, a second Staatsexamen, as well as a PhD degree in Mathematics education, and a teaching award from the University of Vienna.
Research interests: Fundamental problems of networked and distributed systems, especially software-defined networks, optical networks, resilience, consistency, and fault-tolerance, e.g.:
