I am a postdoctoral fellow in the Social Cognitive Science Lab at Harvard University advised by Fiery Cushman and funded by the NSF. I completed my PhD in the Behavioural Science Group at Warwick Business School advised by Nick Chater and Hossam Zeitoun and funded by the ESRC.
I use a combination of behavioral experiments and computational modeling to study the cognitive processes involved in social decision making. This includes how people make moral and fairness judgments, decide and negotiate when interests conflict, and coordinate their behavior to achieve shared goals. My approach is interdisciplinary, drawing primarily upon psychology, economics, and philosophy, as well as other disciplines.
