Dr Radford is a clinical neuropsychologist, conjoint Associate Professor in the School of Psychology at UNSW Science, and Honorary Senior Research Scientist with the Aboriginal Health and Ageing Group at Neuroscience Research Australia (NeuRA). She completed her clinical training and PhD in 2010 at the University of Sydney. Her diverse clinical research experience has involved studying early onset dementia, alcohol dependence, and cognitive rehabilitation for acquired brain injuries, mild cognitive impairment and epilepsy, as well as population brain ageing. This has included experience in a range of research methodologies, such as randomized controlled trials, multicentre studies, longitudinal observational cohort studies, development of psychometric instruments and validation studies.

Since 2009, she has worked with the Koori Growing Old Well Study (KGOWS), an epidemiological study investigating ageing and dementia in urban and regional Aboriginal communities in New South Wales. This research focuses on understanding social and biomedical risk factors for cognitive decline and dementia, and promoting healthy brain ageing in collaboration with urban and rural Aboriginal communities.
