Our research has a primary focus on the effect that social exclusion has on the adolescent brain. To try to answer this research question we are specifically focussed on three main areas: (social) risk-taking, reward processing and social influence. This research promises to contribute significantly to our understanding of how social exclusion shapes adolescent decision-making processes, particularly in the realms of financial, health, and social risk assessment.

To answer our research question, we are using a combination of experimental techniques that include behavioural measures and computational modelling, as well as working collaboratively with other researchers outside of our department. We are always currently undergoing a substantial meta-analysis on the link between social exclusion and risk-taking.

Should you have any questions/ suggestions/ comments, do feel free to email.




Our research examines higher order cognitive effects of social exclusion. We are investigating the effects of ostracism on cognition, in areas such as working memory, mental model construction and risky decision making. 

I am a member of several lab groups:

  • Social Psychology
