I am a postdoctoral researcher at NYU, where I work in Tessa West's lab. I graduated from Bates College with a B.A. in psychology and a minor in dance, and I worked as a lab manager at the University of California, San Francisco before attending graduate school. I earned my PhD in social psychology, with a minor in quantitative psychology, from NYU.
I study fundamental processes in interpersonal interactions. I examine the subtle and overt ways in which people convey their psychological experiences to others and how those communications influence their interaction partners. I ask questions such as: Do women engage with female peers in ways that differ from how they engage with male peers in math and science? Do middle managers in a corporate firm negotiate differently with their lower-status employees versus higher-status senior partners? When meeting someone from a different country, how does the knowledge that one’s partner is from a country that is richer or poorer than one’s own shape how quickly people “tune in” to their partners?
I examine questions regarding interpersonal communication and influence, as well as physiological correlates of these processes, by studying face-to-face social interactions in the lab and in field settings (e.g., at tutor centers and in corporate environments). I capture psychological, behavioral, and physiological processes as they naturally unfold over time, and I develop and employ novel analytic techniques and new methods for physiological and behavioral measurement.
