His research interests are the development of polymer electrolytes, ionomers, and catalysts for fuel cells, alkaline water electrolysers, carbon dioxide electrolyser systems, redox flow batteries, and reverse electrodialysis systems. More specific interests include the use of alkaline anion-exchange membranes (AAEM) and ionomers (AEI) in electrochemical energy technologies, the interface between polymer electrolytes and catalysts, and the use of hydrogen from ammonia cracking in fuel cells. He is co-manager of the EPSRC funded SE-regional Raman Microscopy Facility.
