Research Interests:

                My work takes a 24 hour approach to the study of health behaviors, examining sleep as a mechanism linking lifestyle factors with health and illness.  Broadly, my research considers 1) the complex interplay between waking health behaviors (e.g., caffeine use, smoking, alcohol use, exercise) and nocturnal sleep; 2) the extent to which stress may exacerbate unhealthy 24 hour behaviors; 3) the role of stress and 24 hour health behaviors in the development and maintenance of chronic illness; and 4) sleep promotion in the general population.
