Geoffrey Hammond is Professor Emeritus in the Department of Mechanical Engineering at the University of Bath, and was founder Director of the University's Institute of Sustainable Energy and the Environment (I.SEE). His research interests are mainly concerned with the technology assessment of energy systems, industrial decarbonisation, and energy transition pathways to a low carbon future. This employed methods derived from the engineering and environmental sciences. He was the Principal Investigator [and Co-Leader] of the EPSRC ‘Realising Transition Pathways’ Consortium of nine university partners, and Co-Director of the EPSRC 'Centre for Industrial Energy, Materials and Products' (CIE-MAP). He was co-orginator of the 'Inventory of Carbon and Energy' database, jointy funded by the Carbon Trust and the EPSRC, now widely used for the calculation of 'carbon footprints' for products and in construction. His publications include those for which he was the joint recipient of the Dufton Silver Medal (CIBSE, 1984), the George Stephenson Prize (IMechE, 2009), the James Watt Medal (ICE; twice 2015 and 2021), and the Baker Medal (ICE, 2019). His keynote/invited lectures have been presented nationally and internationally, including the opening keynote address at the 10th International Conference on Applied Energy (ICAE2018) held in Hong Kong (China). Appointed an Output Assessor on ‘Energy and Sustainability’ for the UK Research Excellence Framework (REF 2014).
