Klaus Wehrle is professor of Computer Science and head of the Chair of Communication and Distributed Systems (Informatik 4) at RWTH Aachen University, and affiliated researcher at the Fraunhofer Institute FKIE. 

He received his Diploma (1999) and PhD (Dr.-Ing., 2002) degrees from University of Karlsruhe (now KIT), both with honors. His doctoral thesis on flexible and scalable quality-of-service mechanisms for the next generation Internet was awarded with the Doctoral Dissertation Award of Südwestmetall Association and the FZI Doctoral Dissertation Award (Research Center for Information Technologie, FZI).

In 2002 and 2003, Klaus was postdoctoral researcher at the International Computer Science Institute at University of California at Berkeley (UCB).
In 2004 he was awarded a DFG Emmy Noether (starting) grant and established a junior research group on Protocol Engineering and Distributed Systems at University of Tübingen. 
In 2006, he joined RWTH Aachen University as associate professor, since 2010 as full professor. From 10/2019 till 03/2022 he served as acting head of the Computer Science Department of RWTH Aachen University.

His research activities are focused on (but not limited to) engineering of networking protocols, (formal) methods for protocol engineering and network analysis, network simulation, reliable communication software as well as all operating system issues of networking. 
His research is mainly funded by German Science Foundation (Deutsche Forschungsgemeinschaft, DFG), by the European Research Council (through an ERC CoG and an ERC PoC Grant), the EU, the German government (BMBF, BMWi), the state of NRW and by industrial partners.
Currently, he is co-coordinating the DFG Priority Programme on Cyber-Physical Networking.

He is a member of IEEE, ACM, Sigcomm, GI (German Informatics Society), VDE, and GI/ITG-Fachgruppe KuVS.
He serves as representative for the fields EE and CS in the main evaluation board of Alexander-von-Humboldt Foundation and served as elected representative for communication systems (DFG Fachkollegiat) at the German Science Foundation (DFG). 
Klaus was awarded Junior Researcher of the Year (2007) by the German Association of Professors (Dt. Hochschulverband).
He is member of ACATECH, the German National Academy of Science and Engineering.
