Biography

David started his career as a theoretical physicist, completing his PhD at CalTech under Nobel prize-winner Murray Gell-Mann. His interest in neurophysiology started there under the influence of Prof Jack Pettigrew. David's academic career has been diverse, successively at the National Vision Research Institute in Melbourne, the School of Optometry at the University of NSW in Sydney, the School of Psychological Science at La Trobe University in Melbourne and thence to the Brain Sciences Institute and Swinburne in 2000. His academic interests include neural mechanisms of refractive control, neuroscience of normal and abnormal visual development, psychophysics of visual attention, non-linear electrophysiology and functional neuroimaging of cognitive function. His studies have implications particularly for development in children: dyslexia, amblyopia, autism, myopia and ADHD, as well as understanding of conscious awareness and mind/brain relations. David has published widely with over 130 publications in peer reviewed scientific journals, mainly in the area of vision, visual development, myopia, single cell electrophysiology, evoked potential research, dyslexia, amblyopia, learning disability, and more than 200 refereed conference abstracts. He has an extended record of funding from both the ARC and NHMRC over nearly 30 years as well as other miscellaneous funding, and currently holds an ARC DP (through Swinburne) in the physiological mechanisms of refractive control, a NHMRC project grant (through Swinburne) in the cognitive neuroscience of autistic tendency and an ARC DP (through La Trobe U) into the magnocellular advantage in visual neuroscience. David currently holds an Adjunct Professorship in Psychological Science at La Trobe University and is a Visiting Research Professor at the 3rd Military Medical University of Chongqing, China. He is National Co-Chair of the Asia Pacific Conference on Vision, is on the Executive Committee of the Australasian Society for Psychophysiology, and is the National Imaging Facility Node Director for Swinburne.

Honours topics and outlines

Brain activation to texture defined objects.: It is thought that texture defined objects evoke competitive processing between dorsal and ventral stream areas during figure/ground segregation. We predict that adding small luminance contrast increments to the foreground/background images will dramatically affect the timing of signals involved in recognition. This will change our understanding of the processes of recognition.    

Colour, Motion and Form Individual differences in Autistic tendency – a psychophysical and MEG/EEG study: This question will investigate form and surface colour processing using MEG/EEG , and associated psychophysical tests, with populations low, medium and high in autistic tendency. Due to the fact that MEG recordings will allow source analysis, we will also answer questions of whereabouts the separate processing of form and surface colour occurs in the brain.
