Culture, Ecology, & Social Cognition
Hi there. I am a social psychologist interested in how we adapt to our social and physical environments. The tools of human culture – our shared norms, symbols, schemas, identities – help us as much as hinder us in this task. My research explores this tension using behavioural experiments, cross-cultural surveys, and text analysis.
At present, I am a postdoc in the Department of Psychology at the University of California, Irvine. I received my PhD in Social and Personality Psychology at the University of British Columbia, Canada supervised by Ara Norenzayan and Mark Schaller.
Ecological Cognition
How does culture construct our perceptions of the physical environment and shape the way we make decisions about environmental issues?
Social Cognition
How do motivational goals shape our perceptions of others? And how does social cognition help us achieve our goals?
Culture & Religion
What can social psychology teach us about the cultural evolution of religion? And what can cultural and religious dynamics teach us about the future of our societies?
