Before this he was Chairman of Physics at Oxford. During his career he has authored more than 200 publications. He has been a Visiting Professor in Tsukuba in Japan, Brussels, Padua and Fermilab and holds an Honorary Doctorate from the Joint Institute of Nuclear Research in Dubna, Russia. He was awarded the C V Boys Prize by the Institute of Physics and a Research Award by the Alexander von Humbold Foundation in Germany. In 2004 he was made a Companion of the Order of St Michael and St George (CMG) for services to international particle physics.

Steven CowleyProfessor Steven Cowley –  
Chief Executive Officer, United Kingdom Atomic Energy Authority and Head of EURATOM/CCFE Fusion Association

Steven Cowley became Head of CCFE in September 2008 and was appointed as Chief Executive Officer of the United Kingdom Atomic Energy Authority in November 2009. He received his BA from Oxford University and his PhD from Princeton University. Professor Cowley's post-doctoral work was at Culham and he returned to Princeton in 1987. He joined the faculty at the University of California Los Angeles in 1993, rising to the rank of Full Professor in 2000. From 2001 to 2003 he led the plasma physics group at Imperial College, London. He remains a part-time professor at Imperial College. He has published over 100 papers and articles. Professor Cowley co-chaired the US National Academy's decadal assessment of, and outlook for, plasma science: Plasma Science: Advancing Knowledge in the National Interest (National Academy Press 2007). He is a Fellow of the American Physical Society and the Institute of Physics, and the recipient of the IOP's 2012 Glazebrook Medal for leadership in physics. In June 2011, Professor Cowley was appointed to the Prime Minister's Council for Science and Technology and in May 2014 he was elected a Fellow of the Royal Society.

Martin CoxMartin Cox – Director of Strategy and Technology

Martin Cox is responsible for leading future programmes and technology growth, following his appointment in May 2013. Prior to this he oversaw the MAST Upgrade project and the MAST Project Division. Mr Cox is a theoretical physicist who joined Culham upon graduating, working on plasma modelling. He then became involved in the operation of the experimental facilities. In 1994 he was appointed the Project Manager for the design and construction of the MAST device. From 2000, when UKAEA assumed responsibility for the operation of JET on behalf of the European fusion community, he became manager of Machine Operations Department, overseeing the operation of most of the JET facilities as well as MAST. In 2007 he was appointed Senior Manager for all aspects of JET operation and in 2008 was appointed Assistant Director (Operations), becoming Operations Director following the formation of CCFE in 2009.

David MartinDavid Martin – Chief Operating Officer

David Martin became Chief Operating Officer in March 2016, having previously been Operations Director. Mr Martin is a Chartered Mechanical Engineer and Fellow of the Institution of Mechanical Engineers who joined Culham after completing an apprenticeship at UKAEA Harwell in 1979. Following a role in the build and operation of the Neutral Beam Testbed on JET, he joined the Engineering Group in Neutral Beams before establishing the Engineering Analysis Section. He became Engineering Group Leader and then Department Manager in 2008. In 2011 he was appointed Head of Physics and Engineering Development Division and in 2012 Head of the Operations and Programme Delivery Division. In 2013 he was appointed Operations Director (Operations). He has held other senior engineering posts such as Engineer in Charge and Deputy Chief Engineer. David is committed to staff development and has initiated many of the training schemes presently being run at CCFE – including the apprentice and graduate programmes – helping to achieve accreditation by the Institution of Engineering and Technology, Institution of Mechanical Engineers and the Power Academy.

Catherine PridhamCatherine Pridham – Chief Finance Officer, Director of Support Division, and Secretary of the UK Atomic Energy Authority

Catherine Pridham qualified as a chartered accountant with Arthur Andresen and has worked in the pharmaceutical sector for SmithKline Beecham, Amersham plc and GE Healthcare, where she supported a number of different business areas including a commercial clinical trials business, a large R&D portfolio and a Joint Venture looking to exploit research capabilities commercially with large pharmaceutical companies. Prior to joining CCFE she completed several finance restructuring and process improvement projects for the Ministry of Justice and Department of Transport. She was appointed as CCFE's Head of Finance, Contracts and Integrated Planning in 2012 and became Chief Financial Officer, Director of Support Division and Secretary of the United Kingdom Atomic Energy Authority in January 2014.

Kay NicholsonKay Nicholson – Head of Assurance Division

Kay Nicholson took up the position of Head of Assurance in December 2014 proving assurance to the Board and Chief Executive. Prior to this she was employed by Bentley Motors delivering transformational change in occupational health and safety. In her early career she worked in operational roles in a diverse range of manufacturing industries. In the early 1990s she moved into safety, health and environment (SHE) and specialised in risk management. More recently, Kay has worked in the maritime defence sector for BAE Systems in Glasgow, Portsmouth and Melbourne, Australia, leading SHE improvement and cultural change programmes. She has also worked for QinetiQ UK, where she was responsible for Corporate Governance and Risk Management. Kay is a chartered member of the Institute of Occupational Safety and Health.

William MorrisDr William Morris – Chief Scientist

William Morris has responsibility for providing scientific advice to the Executive, initiating new research areas, assessing the programme and enhancing CCFE’s scientific impact. Dr Morris has spent his entire career in fusion research after a physics degree at the University of Oxford. He made wide-ranging physics contributions to the TOSCA, DITE and COMPASS experiments at Culham, to JET and to the PBX and TFTR devices at Princeton University. He led preparatory studies and the physics proposal for the MAST tokamak before becoming head of Culham’s Experiments Department in 1998. More recently, he co-ordinated initial Culham work on ITER diagnostics. Dr Morris has had many roles in EU fusion programme and project committees, starting with the JET Scientific Council, and he is currently an ad personam member of the EFDA Science and Technology Advisory Committee.
