He is a member of the High Energy Physics group at the University of Manchester, and works on the ATLAS experiment at the Large Hadron Collider (LHC) at CERN, near Geneva, Switzerland. He is working on the R&D project of the FP420 experiment in an international collaboration to upgrade the ATLAS and the CMS experiment by installing additional, smaller detectors at a distance of 420 metres from the interaction points of the main experiments.

He is best known to the public as the presenter of a number of science programmes for the BBC, boosting the popularity of subjects such as astronomy; so is a science popularizer, and science communicator. He also had some fame in the 1990s as the keyboard player for the pop band D:Ream.
