  Incoming and Local
Our regular slot for the Quantum & Gravity seminars is on Fridays at 13.15h in HG02.802, unless specified otherwise.

The other event hosted by the group is an informal brown-bag lunchtime discussion and journal club (currently organized by Timothy Budd - send him an email if you want to join the mailing list) which takes place on Wednesdays at 12.30h in room HG02.802, unless specified otherwise. The schedule can be found here.
