Seminars

Our seminar is organised by Steffen Gielen. Seminars usually take place on Wednesdays at 3.00pm, followed by an informal tea break. We usually aim for broadly accessible talks across the range of research areas represented in the group. In general we have a mixture of in-person seminars and virtual talks (using Blackboard Collaborate).

Details of the seminar programme for the academic year 2023–24 are given below.
