Katherine Thorson

Lab Director

I am a social psychologist and an assistant professor in the Department of Psychology at Barnard College. Broadly, I study interpersonal processes and social relationships. I am interested in understanding how people think, feel, and behave when they interact with others, as well as how people's experiences and behaviors are influenced by their interaction partners. I study these processes at different stages of relationships and within different relational contexts. In addition, my work investigates how people's experiences and behaviors change over time within individual interactions and across repeated interactions with the same partner. My current research focuses on three areas: understanding physiological synchrony, examining responses to stress within social relationships, and investigating how people form new relationships, particularly across differences in social status. In addition, my work focuses on advancing methodological and analytic approaches for studying interpersonal processes. I joined Barnard in 2019, after earning my PhD from New York University (2018) and my BA from Bates College (2010).
