Prof. Greg Metha has been an academic at the University of Adelaide since 1997. He was Head of the Chemistry Department in 2010–2018 and is a Deputy Director of the Centre for Energy Technology. His research uses light sources from lasers to synchrotrons, across the entire electromagnetic spectrum, investigating a range of molecular phenomena to discover new molecules and explore their properties. He heads the Metal Cluster Laboratory which focuses on the exploration of the physical and chemical properties of sub-nanometer sized metallic particles underpinned by advanced computational modelling, the advancement of novel catalysts based on metal clusters, and building novel apparatus and instrumentation including pioneering work developing gas-phase photocatalysis reactors that operate under concentrated radiation. His most recent work involves using light to produce chemical fuels directly from sunlight such as hydrogen from water-splitting, and hydrocarbons from CO2 reduction.
