Professor George AC Murrell Professor George AC Murrell
MD (UNSW), DPhil(Oxon)
Director

Professor George Murrell was appointed Director of the Orthopaedic Research Institute at St George Hospital and Associate Professor at the UNSW in September 1995. He graduated from Adelaide University and was the 1984 South Australian Rhodes Scholar. At Oxford he completed a DPhil (PhD) thesis on "Dupuytren's Contracture" and was awarded the Royal College of Surgeons Arris and Gale medal for this work.

Professor Murrell completed his orthopaedic training at Duke University, USA where he also established a research program on tendon healing and was supported by the Orthopaedic Research and Education Foundation. He then completed a two year fellowship in sports medicine, shoulder surgery and research at the Hospital for Special Surgery, New York. During this time he gained a National Institutes of Health First Award, an American Orthopaedic Association North American Travelling Fellowship.

Professor Murrell specialises in shoulder surgery and has a special interest in arthroscopic methods to repair and restore damaged ligaments and tendons. His basic research interests include the role of free radicals, especially nitric oxide in the musculoskeletal system.

Director of Clinical Outcomes Research

Professor Judie Walton was appointed as Director of Clinical Outcomes Research in September 1998. She also holds an appointment as Conjoint Associate Professor with the University of New South Wales. Professor Walton obtained her PhD in Experimental Pathology in 1975 from the John Curtin School of Medical Research at the Australian National University and then conducted post-doctoral research at the University of California at Berkeley. She has held biomedical research positions at the US National Institutes of Health (Gerontology Research Center) and the Lawrence Livermore National Laboratory (US Department of Energy) in California. After coming to Australia, she worked at Sydney University and then at the Commonwealth Scientific and Industrial Research Organization (CSIRO) at Prospect, NSW. She served as President, and then Vice-President, of the International Federation for Cell Biology from 1992-2000.

Professor Walton's career and consultancies have mainly focussed on research into ageing and age-related diseases. Here at the Orthopaedic Research Institute, her current interest in biomedical research concerns cell changes underlying connective tissue ageing and disease mechanisms. Her clinical research interests, involving biostatistics and clinical epidemiology, are currently directed towards improving the diagnosis of orthopaedic conditions, for example rotator cuff tears (Murrell GAC and Walton JR. The clinical diagnosis of rotator cuff tears, The Lancet 357:769-770, 2001).
