Staff and Directors

Here you can find out a little bit more about the people who work for or help to run SGR, where we've come from and the various routes we've taken to get to where we are today. The page is divided into Staff, Directors, and Advisors to the Board of Directors (the latter two groups are voluntary apart from the two ex-officio Directors). Our Patrons are listed separately.


Stuart Parkinson BEng PhD
Executive Director

Dr Stuart Parkinson began his career studying for a degree in physics and electronic engineering. During an industrial placement, he worked on military engineering projects, and this caused him to question the ethics of his career path. On completing his degree, he changed direction and enrolled for a PhD in mathematical modelling of global climate change at Lancaster University.

After obtaining his doctorate, Stuart then took a postdoctoral post at the Centre for Environmental Strategy (CES) at the University of Surrey, where his research mainly involved work on climate and energy policy, and environmental systems analysis. During this time he became an expert reviewer for the Intergovernmental Panel on Climate Change (IPCC) and provided advice to UK negotiators to the UN climate change convention. He then spent a year working for Friends of The Earth, co-ordinating research and policy work highlighting the link between environmental problems and social injustice.

Stuart became Executive Director of SGR in 2003, having spent the previous five years volunteering on SGR's National Co-ordinating Committee. He is an author/editor of numerous SGR reports, including Estimating the military’s global greenhouse gas emissions; The environmental impacts of the UK military sector; Under the radar: the carbon footprint of Europe's military sectors; Irresponsible science? How the fossil fuel and arms corporations finance professional engineering and science organisations; UK nuclear weapons: a catastrophe in the making?; Offensive insecurity: the role of science and technology in UK security strategies; Soldiers in the laboratory: military involvement in science and technology - and some alternatives; Science and the corporate agenda: the detrimental effects of commercial influence on science and technology; and Shale gas and fracking: examining the evidence. He is also co-author of a book on the Kyoto Protocol, and an editor of the Responsible Science journal. He has also authored numerous popular science articles and academic papers, and given lectures and presentations to a wide range of audiences.

Stuart is an ex-officio member of SGR's Board of Directors.

Andrew Simms MA
Assistant Director

Andrew Simms has a background in political economics and development studies. In addition to post at SGR, he is also co-ordinator of the Rapid Transition Alliance, a co-founder of the New Weather Institute, a research associate at the Centre for Global Political Economy, University of Sussex, and a fellow of the New Economics Foundation (nef), where he was policy director for over a decade. During that time, he founded the nef’s work programme on climate change, energy and interdependence, instigated their ‘Great Transition’ project, and ran work on local economies.

His books include Ecological Debt – on framing the transgression of planetary boundaries – and Tescopoly. He also co-authored The New Economics and Green New Deal. He writes for The Guardian and broadcasts with the BBC World Service and was described by New Scientist as 'a master at joined-up progressive thinking’. His latest book, Cancel the Apocalypse: the New Path to Prosperity, is a manifesto of new economic possibilities.

Andrew is an Advisor to SGR's Board of Directors.


Jan Maskell MA MSc PhD CPsychol

Phil has written widely on the unacceptable risks of nuclear weapons and growing militarism. He co-authors London After the Bomb, and Crisis Over Cruise. He was one of the organisers of the London Nuclear Warfare Tribunal (1983). Since then, he has contributed to or written many articles about the Trident nuclear system, Chernobyl, Zaporizhizhia, UK military strategy and the malign influence of corporations and the military upon science and technology. He was one of the expert witnesses on the impacts of nuclear weapons for the conferences leading up to the UN nuclear ban treaty (TPNW). In 2017, this collective effort was awarded the Nobel Peace Prize.

After leaving academia Phil headed one of the UK's leading and award-winning environmental programmes in Kirklees Council, West Yorkshire up to 2011, where he headed a £6m ($10m) per annum low carbon renewable energy, energy conservation and grants programme. After this, he spent a short period as a vising professor at the University of Leeds working on city-scale low carbon programmes. He was director of a not-for-profit energy company (Yorkshire Energy Services, CIC) up to 2021.
