I investigate fundamental questions about the emergence and utility of nonverbal behavior for the communication of emotion, personality, and social rank. I rely on a variety of methods, including structured group interactions, human-robot interactions, experiments, and longitudinal designs, while leveraging different measurement and analytical techniques including automated and manual nonverbal behavioral coding, peer-reports, machine learning, and psychophysiology. To examine the generalizability of my research findings, I explore these questions around the globe and across ages, including in non-western and small-scale traditional societies, and children as young as two.
