    Jessie Sun's research examines two fundamental aspects of the good life—well-being and morality—in real-world contexts.

    Sun's research aims to understand how people can balance the pursuit of personal well-being with broader moral concerns. Towards this end, she has three main lines of research. First, she examines which kinds of social interactions matter for well-being, and whether different people benefit more from different kinds of social interactions. Second, she studies the causes and consequences of moral improvement. Third, she investigates the psychological connections and tradeoffs between well-being and morality. She uses a range of naturalistic methods to study people in real-world contexts, including experience sampling, audio recordings of people’s everyday conversations, informant reports, and daily life interventions.
