Research Interests
My main program of research examines the relationships between social pain, physical pain, and health. Within the broader construct of social pain, I am especially interested in peer victimization (e.g., being bullied or ostracized) and its influence on physical and psychological health. My main program of research to date has been an effort to determine why people who are bullied report more physical and mental 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). More recently, I am examining when people decide to intervene to assist someone who is showing signs of psychological distress. To address these questions, my research draws from several disciplines of psychology including social, developmental, personality, health, and social neuroscience.
