John Fox is an interdisciplinary researcher with interests in computer science, AI, cognitive science and medical informatics. After degrees at Durham and Cambridge Universities he worked with AI founders Allen Newell and Herbert Simon at Carnegie-Mellon, and with Ulric Neisser at Cornell University in the USA. After a period with the MRC back in the UK he joined the ICRF (now Cancer Research UK) where his group made many theoretical and practical contributions in decision science, cognitive theory and medical informatics, and founded The Knowledge Engineering Review. He has published widely (see Researchgate.org) and has led the foundation of several medical AI companies (Expertech, InferMed, Deontics). A current passion is OpenClinical.net, an open access, open source knowledge repository that uses AI and crowdsourcing techniques to capture and disseminate actionable knowledge of best medical practice.
