Professor Johnson was a member of the scientific advisory board of SMC between 2002-2012.
Professor Johnson was Chairman of PUSET, which was set up by the former government department, the Office of Science and Technology (OST), to improve dialogue between scientists and the public and “demonstrate the relevance of science, engineering and technology (SET) to people's daily lives and its importance to the economy”.  PUSET, as part of the OST, paid COPUS to run a grant scheme on its behalf. COPUS was a funder of SMC between 2003-2006.  The University of Cambridge and EPSRC were also funders.
