Researcher Summary

The majority of my research interests are based around energy and hydrogen technologies. This includes activities on redox batteries, fuel cells, water electrolysis and conversion of biofuels in electrochemical reactors. I have an interest in surface chemistry, particularly using x-ray based methods to understand how and why reactions proceed on various surfaces. I have experience utilising synchrotron radiation to determine structure of materials and the binding of species to surfaces at the atomic scale under industrially relevant reaction conditions.

I have recently completed a Marsden funded project on electrocatalytic CO2 reduction, investigating the production of methanol from CO2 on Cu cathodes. I was also a PI on a project investigating ultra-high temperature electrodeposition of Ti from molten oxides. My current externally funded projects (total $3M) include leading a project on photoelectrochemical redox batteries (direct solar energy storage and conversion), zero-carbon iron production, and recovery of zinc from industrial waste.

In additional to my academic research projects, I have co-founded a start-up company who are now commercializing a waste treatment / metal recovery technology developed in my laboratory.
