David leads the development of major projects and initiatives focussed on providing technology pathways for low emissions energy technologies to increase efficiencies and reduce costs of greenhouse gas reduction options while ensuring secure and sustainable energy supply. David works across the major energy technology sectors including solar thermal and PV technologies; advanced thermal and electrochemical energy processes; hydrogen energy systems; and emissions monitoring, modelling and management. David also has extensive research experience in fundamental and applied aspects of coal combustion and gasification systems. David has published over 170 research reports and papers on a wide range of energy technologies with particular emphasis on carbon, biomass, coal and coke reactivity, high temperature & high-pressure reactions, combustion and gasification technologies and their applications in metallurgical and low emissions power generation technologies. David has well-established collaborative links with the major energy research and technology institutions within Australia and extensive research links with international research organisations and technology development companies in Japan, China, Korea, Europe, USA, India and South Africa. David collaborates with a wide range of academic and industry based research groups and is a regular participant at major national and international conferences and academic and industry fora in gasification, hydrogen, and low emissions energy technology areas.
