Research Interests
My research examines the broad construct of social pain and its relation with physical pain. Social pain is used to describe the affective pain component when actual or perceived damage occurs in interpersonal relationships. Within the broader construct of social pain, I am especially interested in peer victimization (e.g., bullying, ostracism) and its influence on physical and psychological health. According to the Social Overlap Theory, the neural substrates of social and physical pain overlap (e.g., Eisenberger & Lieberman, 2005; MacDonald & Leary, 2005); my research tests whether this overlap may explain why people who are bullied report more physical health problems than those who are not bullied. I hypothesize that the social stress of being peer victimized alters biological processes which, in turn, leads to poorer health. Moreover, I explore possible protective factors (e.g., social support, friendships) as well as alternative explanations for the link between peer victimization and poor health such as individual differences (e.g., Big Five, rejection sensitivity, need to belong). To address these questions, my research draws from several disciplines of psychology including social, developmental, personality, health, and social neuroscience. I am also interested in concepts such as self-regulation, aggression, friendship processes, and personality.
