Research Interests

  • Technologies for mitigating carbon dioxide emissions, particularly from heavy industries (e.g. Iron and Steel, Cement, Chemicals etc.)
  • Carbon dioxide capture and storage (CCS) and air capture (capture of carbon dioxide from ambient air)
  • UK and international climate change mitigation policy
  • Energy efficiency: technologies, policies and barriers to uptake
  • Incentivising behavioural change in order to reduce individual and corporate carbon footprints


  • Mitigation Research Associate, Grantham Institute for Climate Change, Imperial College London, 2011 - Present 
  • PhD, Chemical Engineering, University of Cambridge. Chemical-looping combustion of solid fuels. 2007 - 2010
  • BSc in Chemical Engineering, University of Cape Town, South Africa. 2003 - 2006.
