Dr Williams began his postgraduate career in 1992 at CERN, birthplace of the Worldwide Web, before switching to a similar facility (SLAC) in California in 1998 after gaining his PhD. At SLAC he managed a major intranet redevelopment project, and this inspired Mark to form his first company, Surfability, in 2000 with the help of an Enterprise Fellowship award from The Royal Society of Edinburgh. A partnership with an early cloud computing provider, Extrasys, led to employment in 2005 with their new owners, and Mark went on to run the Extrasys business before helping to sell it on again in 2009. Mark's consultancy practice is Muon Consulting, he blogs at http://blog.muoncloud.com and he is the author of 'A Quick Start Guide to Cloud Computing'.
