Originally from the UK, Dave joined the European Centre for Nuclear Research (CERN) in 1993. He helped design, build and operate the 14000-tonne CMS detector that studies collisions between sub-atomic particles provided by the Large Hadron Collider (LHC). These collisions recreate the conditions of the early Universe, effectively allowing us to explore through both space and time the history of our Universe. CMS came online in 2010 and, just a couple of years later, found evidence for a new particle – the Higgs boson – that helps us understand why our Universe exists at all. After a 2-year hiatus, the LHC will restart in 2015 providing higher-energy collisions that will allow scientists to boldly explore where no scientist has gone before…. In addition to his Project Manager role at CMS, Dave has appeared on many television documentaries and has led the International Particle Physics Outreach Group, bringing the wonders of particle physics into classrooms around the world.
