Second Examiner (Zweitgutachter) / First Examiner (Erstgutachter)

We welcome students who would like Klaus Wehrle to act as the (second) examiner of their Bachelor's or Master's thesis. To create an efficient and effective procedure for deciding whether we can assess your thesis, please carefully read and understand the following information.

Second Examiner (Zweitgutachter)

The decision if Klaus Wehrle can take over the duty as second examiner mainly depends on our available resources and our ability to assess your topic. Please note that we require up to three weeks for grading your thesis after we have received the necessary documents from your first examiner (this typically happens a few days after both your thesis and your thesis colloquium have been graded). Please consider this for your time schedule, especially if you require that your grading is finished by a certain deadline (because you need to enroll for a Master's program or want to receive your certificate at Tag der Informatik / Sommerfest).

To ensure that you get a timely response whether we will and can act as the second examiner for your thesis, please follow the following procedure:

  • If you are enrolled in a study programme that is not one of the study fields directly offered by the Department of Computer Science at RWTH Aachen University (Bachelor, Master), please contact your examination board (Prüfungsausschuss) first to make sure a computer science professor from RWTH is allowed to grade your thesis.
  • Direct your request for second examination to COMSYS via e-mail to thesis(at)
    Please note that mails not directed to this address (especially mails to Klaus Wehrle personally, or to the office staff) will be ignored!
  • Please approach us as early as possible and include the following information:
    • Your full name, e-mail address and matriculation number
    • Your study programme
    • The name of your first examiner (professor / private docent)
    • The name of the post-doc / PhD student advising you (if applicable)
    • The proposed title of your thesis
    • A summary of your thesis topic of 0.5 - 1 pages in length (in German or English). Please be specific enough to allow us to verify that we are able to assess the proposed topic. As COMSYS values thorough evaluations in theses, be sure to also include some initial ideas on how to assess the outcome of your thesis against e.g., state-of-the-art approaches. (Testing whether "it works" is not a sufficient evaluation, also not for a Bachelor's thesis!)
    • Your planned date for submitting your thesis

Normally, you should receive a reply from us within one week. In exceptional cases we might need up to two weeks. If you wait longer than two weeks for a reply or receive an e-mail error, please contact René Glebke as the coordinator of Klaus Wehrle's examiner duties directly.

First Examiner (Erstgutachter) - RWTH-internal / At another university

If you are a RWTH computer science student interested in writing a Bachelor's or Master's thesis with an RWTH institute that is not allowed to grade your thesis as a first examiner, or at another university, you may also check if Klaus Wehrle can take over the duty as first examiner. The respective professor of the RWTH institute should usually be allowed to serve as second examiner in this case. Please follow the same procedure as listed above when asking Klaus Wehrle to serve as a Second Examiner (Zweitgutachter). Please note that we reserve the right to decline first examiner duty if the topic does not match the current research directions of the chair or if the workload is too high. You should thus always contact at least one other professor in case Klaus Wehrle cannot grade your thesis.

First Examiner (Erstgutachter) - With a company

If you are a RWTH computer science student interested in writing a Bachelor's or Master's thesis with a company, please contact us as early as possible via a mail to thesis(at) We have special requirements for such theses concerning cooperation with the companies as well as the scope of the topics. Thus, the earlier you contact us, the higher the chance that Klaus Wehrle will accept to grade your thesis. Please include as much of the information listed in the Second Examiner section as possible in your mail but note that we might ask you to provide an extended abstract of your topic later in the process.
