CV

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

He received his Diploma (1999) and PhD (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 2002 Doctoral Dissertation Award of Südwestmetall Association and the 2002 FZI Doctoral Dissertation Award (Research Center for Information Technologie, FZI).

Supported by a scholarship, he joined the International Computer Science Institute at University of California at Berkeley from 2002 to 2003. In 2004 he was awarded a DFG Emmy Noether 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, later as full professor.

His research activities are focused on (but not limited to) engineering of networking protocols, (formal) methods for protocol engineering, sensor networks, network simulation, peer-to-peer-networking as well as all operating system issues of networking. He is a member of IEEE, ACM, Sigcomm, GI (German Informatics Society), VDE, and GI/ITG-Fachgruppe KuVS.

In 2007, Klaus Wehrle was awarded Junior Researcher of the Year by the German Association of Professors (Dt. Hochschulverband). He is member of the German National Academy of Science and Engineering (ACATECH).

My Email and Exam Policy

Because of a continuously experienced overload of my email inbox ...

I am not able to respond in a timely manner. Please expect significant delays.
I consider my email Inbox as a soft-state system, where emails are valid only for a certain period of time. Specifically, I am deleting all remaining emails in my Inbox on a regular basis (approximately every 7-10 days). In case you are still waiting for an answer longer than this time, your email may have been deleted -- just because of the overload of emails, not because of its purpose or because of the sender :-)
During times on business travel, I may very likely not be able to access or answer emails. This is especially at the following out-of-office dates:
- April 8-11, 15-17
- May 2-3, 18-25, 27-31
- June 3-5, 10-11, 18
- July 17-19, 22-24, 25-31
- August 1-3, ...

Dates for oral exams are offered biweekly, every second Wednesday from 3pm till 6pm.
If you plan to do an oral exam, please follow this procedure:

reserve a slot in advance at the ComSys office (office(at)comsys.rwth-aachen.de) with mentioning your study program and the planned lectures to be examined. We will confirm the combination subsequently.
confirm the exam slot latest four weeks ahead of your exam at the ComSys office (office(at)comsys.rwth-aachen.de). but be sure, that you are well prepared for the exam at that time.
if you plan to have an oral exam with two professors, please check first the availability of slots with the ComSys office and then find a joint date with the other examiner. Then book the final date at the ComSys office.

For teaching related emails, please use the following mail address: teaching (at) comsys.rwth-aachen.de

For scientific, project or other research/universiy-related purposes,
please use the following address: wehrle (at) comsys.rwth-aachen.de

A small note for potential applicants

Please note:

The ComSys Team is a very open-minded and technology-oriented research group. But we are receiving dozens of (mostly unserious spam-)applications per week. To focus on serious applications, we only accept applications sent in by non-electronic mail. eMail applications will neither be processed, nor answered, nor accepted.

eMail applications of any kind will be deleted immediately!

If you are seriously considering to apply for a position (researcher, PhD student, teaching assistant, internship, student research assistant) within the ComSys Team, please spend the small amount of postage for sending your application by postal mail -- you will definitely get an answer. Many thanks for your cooperation!

Klaus Wehrle (Professor)
