Interests and Experience
In my research, I combine social and evolutionary perspectives to understand how people make difficult decisions and navigate tradeoffs associated with everyday life, and the motivations underlying those decisions. I have specific interests in understanding the mechanisms that promote cooperation, as well as the ways childhood unpredictability can influence our downstream decision-making processes.
I am also interested in dark personality traits and relationship science.
