 research interests

I am head of the Electrochemical Systems Laboratory research group.

My principal interests and expertise are in the science and engineering of electrochemical energy conversion, CO2 reduction and separation processes for industrial effluent treatment and material recycling. My academic research projects have all been aimed at solving industrial problems and involved experimental and numerical modelling components. The strategy followed in former, current and future projects is to progress from theoretical assessments of a given problem, to small-scale experimental investigations and process modelling and then on to system design, operation, characterisation and scale-up.

  • Electrochemical energy conversion
  • Water splitting & CO2 reduction
  • Experimental characterisation of semiconductor | electrolyte interfaces
  • Micro-kinetic modelling of (photo-)electrochemical processes
  • Design, characterisation and modelling of scaled (photo-)electrochemical reactor systems
  • Metal recovery by electrodeposition
  • CO2 utilisation

I co-lead the Imperial College Electrochemistry Network together with Dr Ifan E. L. Stephens (Materials) and Dr Clotilde S. Cucinotta (Chemistry). 

I am an Associate Editor for Frontiers in Electrochemical Engineering.

I am the Research Theme Champion in Sustainable Power (Solar) at the Energy Futures Lab.
