Research description

Broadly interested in links between physical activity/inactivity and mental health. Current projects focus on exercise as treatment for alcohol use disorder ('FitForChange'), and yoga-based exercise to promote healthy ageing and wellbeing. I also work with Swedish register data exploring relationships of physical activity, sedentary behaviour and mental health. Recently completed  projects include exercise for depression ('Regassa') and first episode psychosis. Committed to translating research into clinical and public health practice.
