Explanation of Mallen's doctoral thesis, March 2023 George Mallen worked at the Royal College of Art from 1971 to 1983 in the Department of Design Research. His PhD was awarded by the CNAA in July 1976. Mallen had begun his studies under Richard Goodman at Brighton College of Technology and completed them at the RCA under Professor Bruce Archer. The work described in the thesis, modelling information use by police detectives, was undertaken by Gordon Pask's company System Research Ltd for the Police Scientific Development Branch of the UK Home Office. The ideas in the thesis fed directly into Mallen's work for the Department of Design Research, initially focused on modelling decision-making in building-design, but later expanding into the pioneering application of computing to all aspects of design and fine art. In 1968, George Mallen together with Alan Sutcliffe and John Lansdown, founded the Computer Arts Society to promote these ideas to the wider world.
