Personal profile

Research interests

Broadly speaking, my research focuses on topics in judgment and decision-making

Most of my research centers around understanding first impressions. For example, I study:

  • how people form first impressions (what makes a person appear trustworthy or competent?),
  • how accurate these impressions are (can we judge how trustworthy someone is just from looking at a person's face?),
  • the consequences of first impressions (do people prefer trustworthy-looking politicians?),
  • why people rely so much on first impressions (is reliance on first impressions quick and effortless?), and
  • how we can reduce reliance on first impressions

I am also interested in meta-science (e.g., replication, research practices), social dilemmas (e.g., trust and cooperation), and evolutionary psychology (e.g., disease avoidance, mate choice). In my research, I analyze data from the lab and the field, using a variety of methods face classification algorithms, machine learning, reverse correlation, face morphing, and economic games.
