Research Interests

In my group we have research expertise in electrochemical redox reactions at the interface of electrodes and electrolytes and morphology of electrodic materials within an ecological calculus at the cutting edge of new applications. Our research output has attracted worldwide recognition for creating research framework that places emphasis not only on optimising rates of redox reactions while minimizing polarization losses and parasitic reactions but also on design features for recovering materials and components with minimal loss of value. Our research has applications in energy devices, recycling and sustainability and sensors.

In the area of sensors we carry out investigations into operating solid-state ionic sensors in electrochemically active mode. This has led to many practical applications such as on-board diagnostics in gas sensing, self-cleaning and mixed potential sensors for industrial usage and applied to molecular species such as SOx, NOx, H2S, HCl, H2O, CO, CO2 and many others.  We have also integrated oxide materials within silicon-on-insulator, CMOS platform.
