The Centre for Research on Ageing, Health & Wellbeing (CRAHW) aims to optimise the well-being of individuals and communities through the life course by conducting innovative and translational research and contributing to public policy. We work in methodological and theoretical traditions drawn from psychology, sociology and epidemiology that focus on adult development and ageing. The Centre has particular expertise in cognitive ageing and dementia, psychiatric epidemiology, neuroimaging, social gerontology, healthy ageing and substance use. Our work involves conducting and analysing large-scale epidemiological studies as well as intervention studies. CRAHW hosts a node of the ARC Centre of Excellence in Population Ageing Research and a Dementia Collaborative Research Centre.
