Hi! Welcome to my research website! I'm a social/personality psychologist and University professor who studies relationships, emotions, and aggression, often with a biological slant. I use many different kinds of measures and techniques to assess research questions, including surveys, experiments, text analysis, psychophysiology (hormones, facial structure, cardiovascular function), behavioral coding, video games, and dyadic interactions, among others. I also use a variety of statistical techniques to analyze data, including structural equation modeling, multilevel modeling, and factor analysis. At UMass Boston, I teach courses in statistics, social psychology, personality, and close relationships. I also direct the Social Processes, Affect, and Neuroendocrinology (SPAN) lab at UMB.
