Jo’s research continues to focus on health related issues for older people. Currently, Jo is coordinating the clinical trial called Ambient Intelligent Geriatric Management (AmbIGeM) system, which aims to prevent falls in hospitalised older people, through the use of wearable technology. She is also investigating sedentary behaviour and strategies to reduce to this in hospitalised older people.
