Obesity research group

The Obesity research group is interested in establishing the causes of obesity across the lifespan, developing and testing behavioural interventions for the prevention and management of obesity in children and adults, and evaluating obesity-related public health initiatives. We also study energy balance behaviours, including eating behaviour, physical activity and sleep. We have expertise in behavioural and psychometric measurement, epidemiology, behaviour genetics, intervention design, trial management and qualitative research.
