You need the DeLi logos for your seminar or out-of-house presentation?
High-resolution logos of the University of Vienna can be found here.
The seminar takes place in the DeLi Seminar Room (UZA 1, Althanstrasse 14, level 3), dates are usually Mondays, time is 12:00 (s.t.) - 13:00, unless noted otherwise. Seminars consist of a research presentation (~30 min) followed by opportunity for discussion. Then new MSc and PhD candidates present their yet undone projects in the planning phase and hope for constructive feedback (the Supporting Act, ~5min).
