The SC²S Colloquium is a forum giving students, guests, and members of the chair the opportunity to present their research insights, results, and challenges. The colloquium takes place on Fridays, at 3 pm, in room 02.07.023. Guests are always welcome!

Usually, a single talk lasts 20 minutes with 5 up to 10 minutes discussions afterwards. To register and schedule a talk, you should contact Arash Bakhtiari at least one week before the desired date. Add the title, the name of the supervisor (if appropriate), the language of the talk and a short abstract for the webpage.

Students doing their Master's and diploma thesis etc. at the chair are supposed to give two talks: The first presents the topic, the status quo, and the research plan. The second talk presents the thesis' results and insights.
