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 at least July 31 as advised by the RWTH) and we discourage students from working at the chair to help mitigating the spread of the virus as best as we can. Nevertheless, you can contact your (potential) advisor directly via email. In case you are looking for a thesis, also consider visiting our available theses page (accessible via eduroam or the RWTH VPN) or sending a mail to thesis(at)comsys.rwth-aachen.de.

Note lectures are held online, and 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.
