Interview What David did next After seven years as the UK government’s chief scientific adviser, chemist David King is still fighting to keep climate change at the top of the political agenda. Richard Van Noorden meets him

King’s own research group at I think it was an accidental Cambridge, which has around 20 scientists working on the chemistry and physics of surfaces, always has an eye to practical applications – such as developing catalysts for producing in a zero-carbon cycle. The team often works with private sector companies such as Johnson Matthey, Shell and BP. How does King find the time to keep up with the instrumentation and fundamental theory that his group develops? He leaves most of the work to colleague Stephen Jenkins, he says: ‘I’m the wise old person who turns up on Fridays and goes to the seminars, but I still spend time with each of the research students.’

Regulation, regulation, regulation The key to getting any technologies from bench to industry is government regulation, says King, www.chemistryworld.org Chemistry World | July 2008 | 59 Interview BARRY CROSSLEY / ISTOCKPHOTOS / CROSSLEY BARRY process.’ has announced that the volume King is heading up the well-intentioned aim of guiding He says that, when they are of investigator-led funding it can the Smith School of science to concentrate on tackling managing tight budgets, government support will drop by 12–15 per cent. Enterprise and the problems such as climate change departments tend to make cuts across But King stoutly defends the Environment in Oxford resulted in too much regulation of the board rather than protect high science settlement. ‘What we’re academic research? priority areas. ‘If you look at the actually talking about is the ‘We haven’t yet seen an analysis state of the government’s Pirbright distribution and the management of of whether scientists are getting laboratory [which researches farm the cake, not the size.
