David has worked in energy research for over 20 years, both as part of the UK fusion research programme and also as part of the wider European programme. Much of this time he worked on secondment to JET, the main European fusion experiment and the world’s largest, based at Culham Science Centre in Oxfordshire.
Having led the work on JET which was carried out to support the design of ITER, a power plant scale machine beginning construction in France, David now leads the Power Plant Technology Unit, looking at design options for DEMO, a demonstration power station. He also takes a strong interest in developments in other future energy technologies and in the energy market as it progresses towards a more sustainable future. As part of that he leads the UK work on socio-economic aspects of fusion – working with experts in other areas of energy development around Europe, represents the UK on the IEA Fusion Power Co-ordinating Committee and for a time led the IEA activity on socio-economics of fusion. In related work David represented fusion on the UK Energy Research Centre Future Sources of Energy group. In these roles David was simultaneously involved in separate activities modelling UK energy scenarios out to 2050 and global energy scenarios out to 2100, activities which highlighted the strong differences in supply and demand needs over time and across world regions.
