Current interests

Andy Wain has a background in electrochemistry and his research interests include electrocatalysis, heterogeneous catalysis, electrochemical imaging and molecular spectroscopy.


Andy received a Master’s degree in Chemistry from Oxford University in 2003 and was awarded his doctorate in electrochemical electron spin resonance spectroscopy in 2006 from the same institution. He then spent two years as a postdoctoral research associate at California State University Los Angeles, where he focused on novel electrochemical approaches to studying bio-molecule modified interfaces. In 2008, Andy moved to the National Physical Laboratory where he is now a principal research scientist in the Electrochemistry Group.>

At NPL Andy is the lead scientist of the interfacial chemistry and catalysis theme, which aims to support industry through a suite of state-of-the-art tools for characterising catalyst and electrode materials. Andy has worked on a range of projects at NPL, most notably in establishing a capability for electrochemical imaging at a range of length scales. A major challenge in this area has been nanoscale resolution mapping using combined electrochemical-topographical scanning probe techniques. A more recent focus has been the development and application of novel approaches to in situ molecular vibrational spectroscopy (FTIR and Raman). Andy has published over 50 peer-reviewed papers and 3 book chapters. In 2013 he achieved chartered chemist (CChem) status and in 2015 he was admitted as a Fellow of the Royal Society of Chemistry (FRSC).
