Biography

Vaughan Macefield is Foundation Chair of Integrative Physiology at the School of Medicine, University of Western Sydney, and a Conjoint Principal Research Fellow at Neuroscience Research Australia (NeuRA), formerly Prince of Wales Medical Research Institute. A former NMHRC Senior Research Fellow, he completed his PhD at UNSW in 1986, then undertook advanced training in human neurophysiology in Sweden and the USA. In 1994 he established his own laboratories at NeuRA, prior to joining UWS in 2006. Vaughan specializes in recording from single nerve fibres via tungsten microelectrodes inserted into the peripheral nerves of awake human subjects, and is known internationally as a world expert in recording the firing properties of human sympathetic neurones in health and disease, and as a leading investigator in human sensorimotor control. He has active collaborations with many groups in Australia, Sweden and the USA, and has attracted postdoctoral scientists from Sweden, Denmark, Canada and Australia. For the last seven years Vaughan has been examining the changes in control of the autonomic nervous system following human spinal cord injury, extending his research into the study of pain and its effects on the autonomic and somatic nervous systems, using brain imaging techniques (fMRI) to study the processing of pain.
