Lydia joined the School for Policy Studies in November 2017 as the project manager (Senior Research Associate) of the B-Proact1v project. This is a British Heart Foundation funded study of physical activity and screen-viewing in children and their parents, with a specific focus on the influence of families and friends on change in physical activity, sedentary behaviour, and screen-viewing from school years 1 to 6. She has recently been awarded an Elizabeth Blackwell Early Career fellowship (commencing September 2019 for 18 months) to co-produce an intervention to increase primary-school aged childrens physical activity.

Prior to joining the university, Lydia gained a BSc (Hons) in Psychology and Music from the University of Leeds and an MSc in Health Psychology with distinction from the University of Bath.  She then worked as a research assistant for the UK site of the International Study of Childhood Obesity, Lifestyle, and the Environment. Subsequently, Lydia gained a PhD in Health from the University of Bath with a thesis on exercise motivation in young adolescents from the perspective of self-determination theory, specifically the role of families, friends, and PE teachers in determining quality of motivation, exercise, and sedentary behaviour. Following her PhD, Lydia managed her own project looking at daily fluctuations in need support, motivation, body image perceptions, and exercise behaviour, as well as leading on a several consultancy projects within the Centre for Motivation and Behaviour Change at the University of Bath.
