On the broadest level, my research centers on stress and coping. Potentially stressful situations that require active coping responses -- for example, test taking, job interviews, approaching possible romantic
partners -- are ubiquitous and often represent some of the most important moments that people face in life. The research conducted in my laboratory investigates these motivated performance situations from several interrelated perspectives: (1) examining the determinants of experiencing the motivational states of challenge (when personal resources meet or exceed situational demands) vs. threat (when demands exceed resources) during such situations; (2) exploring the relationships between challenge and threat, cardiovascular responses, quality of task performance, and other behaviors; and (3) using cardiovascular responses as covert measures of challenge and threat in order to understand the factors that contribute to resilience and vulnerability to potential stress. My work in this domain emphasizes aspects of the self and group membership. In addition to this laboratory work, my research incorporates field approaches to studying resilience and vulnerability in the context of coping with traumatic life events.
