Biographical details

Chris Bertram graduated in Engineering Science in 1971 and gained his doctorate in 1975 with a thesis on ultrasonic measurement of arterial mechanical properties. He then spent two years working in haemodynamics at Johns Hopkins University’s Department of Physiology as first a postdoctoral fellow and then a research assistant. From 1977 he experimented on unsteady flow separation and modelled collapsed-tube flows at Cambridge University’s Applied Mathematics department (DAMTP), as a research associate of Tim Pedley. In 1980 he was appointed lecturer at the then Centre for Biomedical Engineering of University of New South Wales. He was promoted to senior lecturer in 1985, and to associate professor in 1990, lecturing on signal analysis, medical instrumentation, cardiovascular dynamics, medical imaging and physiological fluid mechanics. He moved to the School of Mathematics and Statistics at University of Sydney in 2010. He has published 89 full papers in peer-reviewed journals, and over 125 conference contributions and other articles. For many years he conducted experiments on self-excited oscillations of collapsed-tube flows, and these investigations still form the most comprehensive investigation of this dynamical system. His current research is on cerebrospinal fluid mechanics, and pumping in the lymphatic system. He has been a member of the World Council of Biomechanics, and an Associate Editor of the Journal of Fluids and Structures, and is on the Editorial Board of the journal Medical & Biological Engineering & Computing.
