Research
My research focus is on electrochemical activation of small molecules such as H+, CO2, N2, O2 and H2O for sustainable production of fuels and chemicals using renewable energy.
My research group apply a variety of techniques including electrochemical, FTIR, XAS spectroelectrochemistry, DFT and stable isotope labelling to study the mechanisms of water oxidation, proton, CO2, O2 and N2 reduction reactions by molecular catalysts or biological enzymes.
