Biography

Professor Crewther began her studies at University of Melbourne then moved to the US to complete her PhD (Cortical Mechanisms of Neuroplasticity) in Neuroscience at Caltech under Nobel Prize Winner Professor Roger Sperry. Sheila has clinical qualifications in Optometry from UNSW and Neuropsychology and Education from UniMelb and these underlie her research into visual and cognitive neuroscience of neuroplasticity in neurodevelopmental and neurodegenerative anomalies. The aim is to use this knowledge to design better behavioural, educational and therapeutic management regimes for neurodevelopmental disorders such as Autism, dyslexia and intellectual disability. Sheila currently has ~150 published papers and book chapters (most of which are to be found on PubMED or ResearchGate.

Research Interest

Her research interests include: Retinal physiology and its role in the aetiology of ocular pathology and refractive errors, The functional role of neuroinflammation and molecular biomarkers in behavioural depression post stroke and Psychophysics, brain imaging and electrophysiology as indicators of attention and depression in recovery following stroke.
