Research Interests:
Electrochemistry is the common thread that runs through all our research. We have worked in a wide range of electrochemical areas including organometallic electrochemistry, conducting polymers, electroanalysis, inorganic electrochemistry, surface modification, electrochemistry of microorganisms and bioelectrochemistry, applications of electrochemistry in wool processing and fabrication and characterisation of carbon nanotube materials.

At present, our research is focused in three areas: covalent surface modification via radicals and other reactive intermediates, electrochemical communication with microorganisms, and applications of electrochemistry in processing New Zealand’s natural products.
