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, diet, exercise) and nocturnal sleep; 2) the role of stress and 24 hour health behaviors in the development and maintenance of chronic illness; 3) sleep promotion in the general population, and 4) sleep health disparities among the American Indian population. Please visit my website for more information on my current projects.
