Research Interests

My research interests lie in understanding how cognitive and emotional factors may prolong physiological and psychological stress responses and the potential health consequences of this persistent activation. To date, my program of research has focused on how repetitive thought processes such as rumination and worry may influence physiological stress responses and sleep—two major health-relevant processes associated with morbidity and well-being. Some questions that I address include: do individuals who ruminate, or mentally rehearse past stressors, have greater increases in the stress hormone, cortisol, in response to a stressful event? Do these cortisol levels remain elevated after the stressor is over? Does rumination on past stressors negatively impact sleep? My work also aims to identify individual- and situation-level factors that may promote or prevent rumination. For example, are some individuals at greater risk for rumination? Are certain stressors more likely to elicit ruminative thought?
