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. He is now working as a post-doctoral researcher on the DESIRE project, aiming to scale-up hydrogen technology.
Blog Post: The mysterious case of the CPE
The epic quest to explain the disagreement between electrochemical impedance spectroscopy and cyclic voltammetry for a disarmingly simple experimental set-up is finally brought to a conclusion. What can possibly explain the striking difference in the observations, which manifest themselves as the enigmatic 'resistance anomaly'. Click on the link to find out.
Blog Post: Constant Phase Elements
In electrochemistry it is common to come across behaviour that can only be modelled using a constant phase element (CPE). For example, a measurement taken using electroimpedance spectoscopy (EIS) often produces a flattened or depressed semi-circle on a Nyquist plot. This indicates that a form of capacitance is present (coupled with a resistance), but it is non-ideal.

Blog Post: UK Hydrogen Trains
The BBC this morning has news of a the UK's first hydrogen train. This is interesting news, but what's more interesting is that this is being driven by the UK government's commitment to phasing out diesel-only trains within the next 20 years. This could end up having a profound effect on hydrogen powered transport of all varieties.
Blog Post: Changing Fuels
Climate Change is somewhat scary, and much of the time for those that have grasped how dire the forecasts actually are, it's difficult to think of something constructive that can actually be done. Here's one attempt at doing just that.
