Summary
Electrochemical Science & Engineering
Greg is part of the large interdisciplinary and multi-departmental Electrochemical Science and Engineering group. He is based in the Department of Mechanical Engineering and his research is based around battery, fuel cell and supercapacitor technology, and their application, mostly in transport. From the fundamental science to integration and systems engineering. The problems he investigates tend to emerge at the interface between the science and engineering.
The ESE group in Mechanical Engineering is a diverse, inclusive and welcoming group, with researchers from all over the world representing multiple cultures. We strive to answer some of the hardest questions in our research area, and to work with industry to translate the knowledge gained into significant impact, improving the global environment and the lives of millions of people around the world.
Greg has worked with multiple industry partners, and successfully delivered multiple Innovate UK and industry projects. Greg is the Principle Investigator of the Faraday Institution funded Multi-Scale Modelling project, which helped create the PyBaMM and DandeLiion modelling environments. Much of the groups work on physics based modelling of lithium ion batteries is now contributing towards the growing PyBaMM global community.
Greg is a prolific entrepreneur and his research group has led to multiple spin-outs, Galvanic Energy Ltd, Cognition Energy Ltd, Breathe Battery Technologies Ltd, About:Energy Ltd and Ionetiq Ltd (only some of which he is personally involved). He is also the co-founder of one of the premier automotive conferences in the UK, the Future Propulsion Conference (FPC) series.
Greg obtained his PhD at Imperial College London in 2003-2006 under the supervision of Prof Anthony Kucernak on polymer electrolyte membrane fuel cells, and then worked with Prof Nigel Brandon on solid oxide fuel cells. Greg has taken a few short breaks from science, working as a managment consultant, and as an advisor to Government and Parliament.
