I am active in the study of B mesons, having worked at the B factory experiments: (2001-2005) Belle at KEK, (2005-present) BaBar at SLAC (Warwick page), and (2008-foreseeable future) LHCb at CERN. I was physics co-ordinator for the international LHCb collaboration for the calender years 2012-13, I served as LHCb UK spokesperson 2016-20, and since 2020 I am PI of a project for R&D focussed on LHCb Upgrade II. I am a member (and ex-co-leader) of the Heavy Flavour Averaging Group, for which I also have responsibility for averaging measurements related to the angles of the Unitarity Triangle. and am also a member of the Particle Data Group.
