My work focuses on the description of "interpersonal structure" (i.e., the psychological dimensions along which social behavior varies), and on the modeling of the mental representation of interpersonal behavior and of the social context in which it occurs. This work has implication both for traditional social/personality psychology, and for a number of related theoretical issues (e.g., the possibility of distinguishing "universal" from culture-specific psychological processes, and the emergence over time of the dimensions along which meaning about interpersonal behavior is communicated).
