Ajay Gambhir is a Research Fellow at the Grantham Institute for Climate Change. His focus is on the economics and policy of low-carbon technologies. During the past three years he led studies on long-term low-carbon pathways in China and India, was a peer-reviewer for the International Energy Agency's World Energy Outlook 2012, and was part of a cross-College team that investigated the mitigation options and costs towards a 2 degrees C global warming target, published in the report "Halving global CO2 by 2050: technologies and costs".

Before joining the Grantham Institute in 2010, Ajay worked for the UK Government in a range of policy and economist roles, most recently as the team leader for EU and international climate change economics at the Department of Energy and Climate Change. Before that he worked as an economist in the Committee on Climate Change, and as a policy advisor in the Office of Climate Change team that designed the Climate Change Bill, which became an Act of Parliament in 2008. He has also worked in the Prime Minister's Strategy Unit and Department for Work and Pensions, as well as for several years in the telecoms and IT industry.

He holds Masters degrees in chemical engineering and economics and is currently undertaking a PhD (at the Imperial College Centre for Environmental Policy) on the future economic prospects of low-carbon energy technologies.
