The UPDICE consortium held its two-day summer meeting at University College London on the 4th and 5th August 2025. We were very grateful to have two of our International Advisory Board members, Prof Dan Neumark (Stanford University) and Prof Toshinori Suzuki (Kyoto University) present to join in discussions and give their valuable feedback on the Programme Grant. Scientific presentations from each Work Package and Cross Cutting Activity were delivered, followed by a joint symposium with the COSMOS group at UCL.
