I research the processes involved in situations where one person's good (what we may call selfish or impulsive behavior) conflicts with the choices that will produce good for the larger group, community, or culture. This conflict between contingencies, what we may call "social dilemmas" or "social traps,"  is the basis of many social issues we face today, from climate change and sustainability to corruption. I address those issues in conceptual, experimental (lab), and translational studies.
