The UCL Radar group has a regular seminar series at 2:30 pm every Friday. The talks last between 20-40 mins and are given, in turn, by each member of the group. The seminars are organised by Ryan White ryan.white.23@ucl.ac.uk, so please contact him if you or somebody you know would like to give a talk.
We also have a group YouTube channel https://www.youtube.com/channel/UCI5KZFVKvLPqntR5HMoDb_Q featuring regular and invited talks.
