Glenda Margaret Halliday, PhD, received her degrees from the University of New South Wales and her postdoctoral training in South Australia prior to returning to Sydney as an Australian Research Council Queen Elizabeth II Fellow. She has been a research fellow of the National Health and Medical Research Council of Australia since then, currently working at the Brain and Mind Centre, University of Sydney. Her expertise is in the pathogenesis of neurodegenerative disorders, having published over 500 research papers and two books, the most recent on Parkinson’s disease. She was president of the Australian Neuroscience Society from 2006-2007. Her research has highlighted broader pathological involvement in Parkinson's disease and in dementia with Lewy bodies, initially finding that more than the dopamine system was damaged, and then that Lewy bodies associated with visual hallucinations rather than a loss of function. Her current work focuses on how proteins identified through genetic studies are involved in neurodegeneration.
