Generally, my research examines the role that positive emotions and social relationships play in influencing health outcomes. I am especially interested in exactly how these factors "get under the skin" to influence our well-being. Pathways that I have examined include physiological processes such as stress hormone reactivity, cardiovascular response, immune system change, as well as health behaviors like sleeping, exercise, and other leisure activities. I also do research on the role of these positive psychosocial factors in buffering the detrimental effects of stress. For example, I am interested in whether happier individuals are better able to handle stress, both from a psychological and a physiological standpoint. I am also very interested in using relationship and emotion markers outside of self-report as predictors of health. Recently I have begun using computerized word encoding of writing as well as facial emotion expression as alternative, unobtrusive methods of understanding individual differences with interesting results. If you would like to get involved with this work either as a research assistant or a graduate student, please get in touch with me. I'm always looking for motivated students to join the lab.
