Dr Joyce Siette


Research Theme Fellow Health and Wellbeing

Research Program: Brain Sciences


Joyce is currently leading a program of research combining psychology, social psychiatry and public health to identify the social risks, causes and consequences of risk factors on dementia. Her research vision is to maximise the real-world value of research on reducing dementia risk, and to move us towards optimally effective digital interventions to support healthy lifestyles and quality of life in older adults.

Her research is largely focused on understanding the behavioural and social mechanisms underpinning healthy brain lifestyles in older adults. She commenced her research journey at University of New South Wales where she found that voluntary running completely reverses the profound degradation of neural efficiency that accompanies sedentary ageing. Her interest in the processes supporting successful ageing was extended during a postdoctoral position in social psychiatry at Queen Mary, University of London, the only WHO Collaborating Centre for Mental Health Service Development, where she led a team to evaluate the impact of befriending programs on mental health.

Between 2015 and 2021, Joyce was a Research Fellow at the Australian Institute of Health Innovation, Macquarie University and used data analytics to build an Australian context-sensitive health informatics framework for older adults receiving aged care.

In 2022, Joyce moved to the MARCS Institute and the School of Computer, Data and Mathematical Science to continue her journey in unravelling the social determinants of cognitive impairment in older adults and to explore how digital health and informatics, data analytics and interoperability  can support healthy brain ageing.
