Harry Cliff is the Science Museum Fellow of Modern Science, which he reckons might be the only job title which begins and ends with 'science'. He spends half his time searching for signs of new physics at LHCb, one of the four big experiments at CERN's Large Hadron Collider. For the other half, he indulges his love of talking about physics at the Science Museum, where he develop exhibitions, events and online content.
This Q&A was filmed in the Royal Institution on 31 October 2017.
