Temporary Policy Adaptions Due to Current Coronavirus Outbreak

Dear Students,

we are still in the corona pandemic. As before, COMSYS continues to supervise ongoing and future theses, seminars, and preseminars. Lectures are held in a hyrid fashion this winter, stay tuned for information regarding exams. We have established special, individual treatment for oral exams and thesis talks, so please read those if you plan to have an oral exam or give a thesis talk soon.

If you are interested in writing a thesis with us, you can find open topics on our available theses page (accessible via eduroam or the RWTH VPN). However, we are currently experiencing an increased pro-active interest in our topics, i.e., we recommend that you contact your (potential) advisor directly via email and ask for availble theses that are not advertised on our homepage. You can work on your thesis at the chair again during your thesis. Please contact your (potential) advisor for details.
