Biography

Dr. Aaron T. Marshall received his BTech (Hons) before completing his MTech(Hons) from Massey University in 2002. In 2005 he received his PhD from the Norwegian University of Science and Technology (NTNU), Trondheim, Norway. Aaron’s thesis was focused on electrocatalytic oxides for the anodic evolution of oxygen, for which he received the ExxonMobil prize for best technical thesis that year. From there, he returned to Massey University for a short research period in the Institute of Technology and Engineering before taking a postdoc position with Bill Williams investigating the nanomechanical properties of single molecules using AFM. In 2007, He was awarded a FRST postdoc position to investigate noble metal oxides as electrocatalysts at Massey University, before joining the Department of Chemical and Process Engineering, University of Canterbury as a lecturer in 2009. Aaron’s research interests are based around electrochemical engineering, including hydrogen production and fuel cell technology. The majority of Aaron’s work focuses on electrocatalysis, particularly understanding the structural and electronic factors behind electrocatalytic activity. This involves the synthesis of electrocatalytic materials followed by detailed physicochemical analysis using XRD, XAS, XPS and electron microscopy before using an array of electrochemical techniques to characterise the electrocatalytic activity of the materials. Ultimately, his goal is to develop better electrocatalysts by using fundamental understanding of what makes electrocatalysts more active rather than the more traditional “trial and error” approach. This is a major goal of fundamental energy research (Whitesides & Crabtree, Science, 2007, 315, p796). To date, Aaron’s research has focused predominately on the oxygen evolution reaction in both acidic and alkaline electrolytes on nanostructured conductive metal oxides such as IrO2, RuO2, Co3O4 and various Ni oxides but more recently, Aaron is has been investigating electrocatalyst for glycerol oxidation as a means of producing both fine chemicals and electric power.
