I am a mixed-methods behavioural scientist with a background in health psychology, economics and epidemiology. My current research investigates the impact of complex health-behaviour patterns on chronic disease in older adults. I am interested in using big data and longitudinal studies to investigate the impact of commercial determinants on dietary behaviour, consumer choice, and health.

I am currently pursuing my PhD at the Healthy Lifespan Institute at the University of Sheffield, where I use cluster-analytic techniques to segment populations into definable risk groups based on their health-behaviour patterns over time. This approach challenges traditional approaches that focus on individual behaviours, by allowing us to examine complex behavioural patterns and their health impact. These findings can be used to develop targeted interventions for specific subpopulations at high risk for chronic diseases.

Before joining the Healthy Lifespan Institute, I conducted behavioural and epidemiological research on food choices, diet, and health. For instance, I examined the effects of "nudge-like" changes on food intake at the University of Bristol Nutrition and Behaviour Unit and investigated how parental perceptions of childhood obesity in China influence subsequent treatments. I also conducted behavioural analysis for the Antibiotic Research in Care Homes (ARCH) to reduce unnecessary antibiotic use in care homes.
