Klaus Wehrle is Professor of Computer Science and Head of the Communication and Distributed Systems Group (Informatik 4) at RWTH Aachen University,
He received his diploma (1999) and his doctorate (Dr.-Ing., 2002) from the University of Karlsruhe (now KIT), both with distinction. His doctoral thesis on flexible and scalable Quality of Service mechanisms for the next generation Internet was awarded the Doctoral Dissertation Prize of Südwestmetall and the FZI Doctoral Dissertation Prize (Research Center for Information Technology, FZI).

In 2002 and 2003, Klaus was a postdoctoral fellow at the International Computer Science Institute at the University of California at Berkeley (UCB).
In 2004, he received a DFG Emmy Noether (starting) grant to establish a junior research group on protocol engineering and distributed systems at the University of Tübingen. 
In 2006 he joined RWTH Aachen University as an associate professor, since 2010 as a full professor. From 2019 to 2022 he will be acting head of the Department of Computer Science at RWTH Aachen University.

His research activities focus on (but are not limited to) the engineering of network protocols, (formal) methods for protocol engineering and network analysis, network simulation, reliable communication software, and all operating system issues of networking. 
His research is mainly funded by the German Research Foundation (DFG), the European Research Council (through an ERC CoG and an ERC PoC grant), the EU, the German government (BMBF, BMWi), the state of North Rhine-Westphalia (NRW), and industrial partners.
From 2015 to 2023 he was coordinating the DFG Priority Program on Cyber-Physical Networking.
He is a member of IEEE, ACM, Sigcomm, GI (Gesellschaft für Informatik), VDE and GI/ITG-Fachgruppe KuVS.
He was/is a member of several evaluation boards of the Alexander-von-Humboldt Foundation and serves as an elected representative for communication systems at the German Research Foundation (DFG).
