Overview

My research to date has focused on how the food environment influences the food choices people make within them. People and the environments in which they exist interact in complex ways. Through influencing contextual factors within these environments, my research explores how behaviour can be influenced for the better in field-based trials, and tries to provide a better understanding of the circumstances that can foster healthier behaviour, and those that can unintentionally foster less healthy behaviour.


Healthy Vending


In a collaboration with the Aneurin Bevan University Health Board, Public Health Wales and their vending provider, I have run two hospital-based randomised controlled trials on healthy vending, to evaluate an intervention adopted in the Welsh hospital healthy vending directive. We used sales data from vending machines and a hospital shop to evaluate the impact of completely replacing unhealthy products, and introducing NHS labels within machines. I have also run several online studies exploring health labelling and its impact on consumer product evaluations. 


Behavioural Spillover


My experience of applying behaviour change principles to the environments in which people make choices has also helped me develop a skillset that lends itself well to research relating to environmental psychology. Through undertaking a placement with Prof Lorraine Whitmarsh, I gained experience of collecting data measuring pro-environmental behaviours and behavioural spillover. Inspired by my placement, I have conducted a series of experiments exploring the behavioural spillover of food choices, asking whether healthy choices can licence subsequent less healthy behaviours, and whether less healthy choices can lead to subsequent compensatory healthy behaviours.
