Personal profile

Research interests

My research focuses on topics in social perception and decision-making. I study how people form first impressions (what makes a face look trustworthy?), how accurate these impressions are (can we infer personality traits from facial appearance?), and when and why people rely on first impressions when interacting with others. To answer these questions, I analyze data from the lab and the field, using a variety of methods such as facial recognition software, face morphing, and economic games.

Other areas of interest: trust and cooperation, meta-science, judgment and decision-making, evolutionary psychology, research methodology
