Holly Knight is a senior research fellow at the University of Nottingham who has significant experience developing health programme evaluations. She has an interest in how we can better understand the factors that underpin successful intervention delivery and implementation, including the mechanisms predicting individual change. She has worked within multidisciplinary teams to explore lifestyle change for both diet and physical activity in chronically ill populations, with her PhD thesis focussing on supporting physical activity adherence in community exercisers. Her work has spanned academic, consultancy, and clinical settings, and draws from both quantitative and qualitative methodologies. Holly has supported the delivery of multiple national trials with a range of stakeholders including patients, the public, local providers, and government bodies. Holly is also a clinical psychologist and has a specific interest in the evaluation of behavioural and mental wellbeing programmes.
