Bill originally graduated from Keble College, Oxford in 1994 with a 1st class honours degree in Engineering Science. At the time he had no ambition to pursue an academic career, so instead he spent 10 years as an integrated circuit designer at the Rutherford Appleton Laboratory near Didcot. One highlight of this period was the FENIX project, which involved 50,000 ICs installed at the large hadron collider (LHC) in CERN, which ultimately helped to discover the Higg's Boson. The other was designing two ICs for the Rosetta mission, which landed on comet 67P/Churyumov–Gerasimenko in 2014. After a further 11 years working in IT, Bill followed his passion for science and the environment by enrolling on a full-time PhD in electrochemistry.
