My research examines how people’s emotional responses to daily stressors shape their long-term physical health
across the adult life span. I am particularly interested in the effects of emotions that linger after a stressor is over. My work examines potential biological (e.g. cardiovascular) and behavioral (e.g. sleep) pathways that link emotional responses to stress and health. Additionally, I investigate individual differences in emotional responses to daily stressors in an effort to identify who is most vulnerable to the negative effects of stress and identify interventions that promote healthy aging. I use a multi-method approach, using both naturalistic longitudinal designs and lab-based studies to assess physical health as a life-long process that is influenced by a culmination of emotional experiences to daily events.
