The departmental colloquium is a monthly event where a mathematics or statistics expert gives a talk at a level generally accessible to department staff and graduate students. The duration of the presentation is 45 minutes with an additional 15 minutes for questions. The talk is followed by mingling with food and drinks. The colloquium provides a nice setting to bring our whole department together once a month.
