Dave Charlton obtained his PhD on the UA1 experiment with the Birmingham team, searching for production of the top quark in proton-antiproton collisions on the CERN SppS collider. He then spent twelve years investigating a range of topics related to the physics of Z and W bosons at the CERN LEP collider with the OPAL Collaboration, first working for CERN then returning to Birmingham. During this time he was first Trigger, then Physics Coordinator of the international OPAL Collaboration of around 350 physicists.
After the year 2000, when LEP finally stopped, Dave led the construction in Birmingham of readout hybrid circuits of detector modules for the ATLAS particle tracking detectors, and then worked on the trigger systems, where he led the work of the six-institute (UK, Germany, Sweden) first-level calorimeter trigger collaboration. In 2007 he became Deputy Physics Coordinator of the entire ATLAS Collaboration, then Physics Coordinator in 2008. Between 2009 and 2013 he was Deputy Spokesperson of the Collaboration, including during the times of the Higgs boson discovery in 2012. Since early 2013 he has been Spokesperson of ATLAS.
Dave conceived and led a Y3 design group studies for several years, and also introduced and taught a Y4 module “Current Topics in Particle Physics”. While Spokesperson of ATLAS his lecturing is temporarily in abeyance, although he looks forward to returning to teaching in future.
