Sarah completed a Psychology degree at the University of Surrey in 2012 and a MSc in health psychology at King’s College London in 2015. Between studying she has worked as a research assistant on a range of clinical trials relating to diabetes, cardiovascular disease, lung disease and dissociative seizures. Sarah’s research interests are health behaviour change, public health economic modelling and determinants of weight loss maintenance. She is also interested in how psychological theory can inform health economic evaluations.
In her first year, Sarah undertook research attachments looking at public support for public health policies, the relationship between diet and other health behaviours, and the causal relationship between wellbeing and health behaviour. She completed modules in Economic Evaluation, Cost-effectiveness Modelling, Advanced Simulation Methods, Valuing the Benefits of Health Care, and Medical Statistics and Evidence Synthesis.
Sarah completed a 6-week internship at the University of Sydney, Australia where she conducted a review investigating the implications of the increasing use of Online Food Delivery on public health nutrition policy.
Title of PhD
The Feasibility of Including Psychological Factors in Health Economic Models of Obesity.
Alan Brennan, Paul Norman, Penny Breeze
Sarah is examining the psychosocial factors associated with weight trajectories during and after a weight-management intervention and investigating the impact of including relevant psychological factors within a health economic model of obesity on estimates of cost-effectiveness.
Sarah has received training in Decision Modelling using R, Structural equation modelling in mplus, Latent growth curve modelling in mplus, and Laying the foundations for effective writing. She has also presented a poster at the Lancet Public Health conference and presented her PhD research at the UK obesity conference. Through her varied teaching roles as a graduate teaching assistant, she has achieved Fellow status of the Higher Education Academy.
Sarah has published the following paper:

“The programme provides so many opportunities alongside continued support and encouragement from developing a research idea to carrying out the research. Since starting the programme I’ve had the opportunity to learn a new discipline, practice research skills, present at conferences and gain teaching experience. I’ve met decision makers from a range of organisations, been able to collaborate with a team at another university and completed an internship abroad to gain a different perspective on my research area”.
