What is normal brain ageing? An investigation of changes in brain structure and cognition in mid-life. Pathological brain changes associated with cognitive decline later in life become detectable in the 40s and sometimes earlier, yet little is known about what constitute normal brain ageing in midlife. Using a number of neuroimaging techniques, this project will develop a detailed map of brain and cognitive ageing in middle-age and their predictors.

Summary
Harnessing life-course transitions to optimise time-use behaviour habits. At every stage of life, how we use our time is one of the greatest determinants of our happiness, productivity, social wellbeing and quality of life. Time-use habits, for better or worse, are entrenched in daily routines that are difficult to break. This project aims to use existing population datasets to identify when during their life people are most likely to change their time-use habits, and to describe who may be at g ....Harnessing life-course transitions to optimise time-use behaviour habits. At every stage of life, how we use our time is one of the greatest determinants of our happiness, productivity, social wellbeing and quality of life. Time-use habits, for better or worse, are entrenched in daily routines that are difficult to break. This project aims to use existing population datasets to identify when during their life people are most likely to change their time-use habits, and to describe who may be at greatest risk of making unfavourable changes (e.g., replacing physical activity with sedentary time, not getting enough sleep). Expected outcomes include new analytical methods to understand time-use routines and new knowledge to inform future time-use improvement strategies to enable Australians to live their best life.Read moreRead less
Enhancing adolescent mental health through positive education. Positive education is a preventative, strengths-based approach to address the mental health needs of young people in schools. This project will use innovative methods to examine the contribution of positive education to adolescent mental health, and to social and learning outcomes; and will also guide effective and widespread dissemination of positive education, more generally.
Online and offline social networks and the development of sexual agency. This project will explore whether there exists a relationship between adolescents' social networks (both online and offline) and one important aspect of healthy sexual development - the development of sexual agency - and if so, it will investigate the nature of that relationship. The longitudinal mixed methods study proposed here aims to capture the development of sexual behaviours and the online and offline interactions ad ....Online and offline social networks and the development of sexual agency. This project will explore whether there exists a relationship between adolescents' social networks (both online and offline) and one important aspect of healthy sexual development - the development of sexual agency - and if so, it will investigate the nature of that relationship. The longitudinal mixed methods study proposed here aims to capture the development of sexual behaviours and the online and offline interactions adolescents engage in. This project aims to determine: whether there is a relationship between adolescents' online and offline social networks and the development of sexual agency; if such a relationship exists, what is its nature? And, if the relationship exists, to what extent is the relationship moderated by online social media use?Read moreRead less
Neuroimaging changes underpinning improvements in cognition in the elderly. Natural supplements are often used to improve brain and cognitive function, however, we do not know how these supplements work in the brain. Using novel brain imaging scans, the project will investigate whether 12-month administration of two promising natural supplements improves brain markers of ageing and cognitive decline in an elderly population.
Investigating the dynamics of migration and health in Australia: a longitudinal study. This project will investigate the dynamics of changes in health and the factors that moderate or otherwise influence those changes over time among immigrants relative to non-immigrants in Australia. This understanding will contribute to several areas of policy formulation, in turn allowing the question 'how can we best intervene' to be answered.
Improving the diagnostic accuracy of detecting functional decline in older people discharged from hospital emergency departments. There is no accurate early screening tool to detect the loss of ability in older people to live independently. This research evaluates a new screening tool to identify the risk of functional decline. This will assist hospital staff to put appropriate discharge plans in place to mitigate against functional decline.
Harnessing recreational infrastructure to improve physical activity and community well-being. This project will investigate the impact that establishing a major recreational and aquatic centre has upon physical activity and measures of community well-being. It will also test the effect of different marketing strategies on community members' usage of the centre.
