Sir Henry Dale Fellow
Behavioural scientist focused on healthier, sustainable and equitable food purchasing and consumption
I lead the Food Purchasing group, which is part of the Health Behaviours team. My research interests include exploring the effectiveness of different interventions that alter aspects of the physical micro-environment (also known as 'choice architecture' or nudges) to improve the healthiness and sustainability of diets. I am interested in understanding the mechanisms underlying the impact of such interventions, and their potential impact on health inequalities.
I am currently working on a Wellcome Trust & Royal Society Sir Henry Dale Fellowship, which aims to establish the extent to which evidence from interventions to support healthier diets can inform interventions to create urgently needed sustainable diets. Evidence from interventions targeting unhealthy diets could help quickly narrow down our choice of interventions to increase sustainable food selections. However, we need to ensure that the effectiveness of interventions does not change when targeting sustainability. We also want to identify interventions that work for those in all socioeconomic positions, so these do not increase inequalities.
