Our teams: EpiAgeing

I undertook my post-doctoral research between 2010 and 2014 at University College London (UCL) and was recruited to Inserm in 2015.

My primary research is on the role of health behaviours in shaping old age outcomes such as dementia, disability, and frailty.

I set up the Whitehall II accelerometer study in 2012 and have led the methodological and substantive research to study the role of objectively measured physical activity and sleep for ageing outcomes. This has led to a project on circadian rhythm and dementia using data from a general population and memory centre patients, funded by an ERC Consolidator award (2023-2028).
