Research Interests
My group’s research focuses on how human memory works and how it changes with ageing. We are using brain imaging and behavioural methods to investigate how neural changes in ageing affect the formation and retrieval of memories for specific events (episodic memory). In other studies, we are interested in changes in online (working) memory, and complex motor skills (procedural memory).  A key issue is whether qualitative changes in patterns of brain activity in older adults are adaptive - perhaps helping ‘successful’ cognitive ageing - and how best to study these changes. Other current projects investigate the role of dopamine in memory during ageing, changes in functional lateralisation, and the apparent increase in false memory in older adults.
