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) factors that influence sleep-related decisions and behaviors, 3) the impact of sleep on disordered eating behaviors and weight-related health outcomes, and 4) sleep health promotion in the general population. You are welcome to visit my website for more information on my current projects and my google scholar profile for a complete list of publications.
