James Reynolds is a Research Associate in the Behaviour Change by Design programme at the University of Cambridge. His previous work has investigated health behaviours from a number of different perspectives. This includes the effects of drug use on cognition, the social dynamics of weight loss, and testing interventions to improve eating behaviours. His work at the Behaviour and Health Research Unit focussed on the public’s beliefs and attitudes about the government’s role in changing health behaviours. He is now investigating how altering aspects of the physical environment can change health behaviours.
