Temporary Policy Adaptions Due to the Corona Pandemic

Dear Students,

COMSYS is back to normal operation again. However, we strongly encourage our students to continue wearing face masks at the chair. For the modalities of your student meetings, please discuss an individual policy with your supervisor. We also updated our policy regarding oral exams and we will offer a hybrid mode for thesis talks for the time being.

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.
