Drawing on social psychological principles, I investigate how cues in the environment impact health behaviours, and how this knowledge can be translated into effective behaviour change interventions to improve health and reduce inequalities. The bulk of my work to date has looked at how cues such as labelling and advertising affect people’s decisions to eat (un)healthily, drink alcohol, and/or smoke tobacco. Another strand of my research has focused on developing and evaluating interventions to increase societal equality and egalitarianism more generally.
