Temporary Policy Adaptions Due to Current Coronavirus Outbreak

Dear Students,

despite the current coronavirus outbreak all over the world, COMSYS still supervises ongoing and future theses, seminars, and preseminars. Most staff is currently working from home (presumably until end of next March following the home office guidelines issued by RWTH). Lectures continue to be held online, and note that strict hygiene requirements hold for written exams according to university-wide policy. 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). You can also dircelty contact your (potential) advisor directly via email to ask for/discuss your own topics.

Please note that the E3 building in which our chair is located remains closed to the public for the time being. In special circumstances, you can however work at the chair again during your thesis. Please contact your (potential) advisor for details.
