Research Groups
Research Summary

Current research focuses primarily on physical activity in older adults. Older adults are a rapidly growing population group and are also the least active and most sedentary age group. We are collecting year on year objective measurements of physical activity and sedentary behaviour in community dwelling older adult cohorts. The data will help us to understand trajectories of change in physical activity in later life and also to investigate the associations between both the total amount and patterns of physical activity and sedentary behaviour in relation to cardiovascular health in older age, including markers of subclinical disease and CVD events. Related projects include intervention studies to reduce sedentary behaviours in older adults, and an economic evaluation of physical activity interventions across the lifecourse.
Other research focuses on the aetiology of cardiovascular disease, including the role of novel inflammatory makers as well as genetic association studies.
