Research Focus:

As a researcher with significant training in exercise science and sleep medicine, Dr. Kline's research focuses on the use of physical activity as a nonpharmacologic/behavioral treatment for disturbed sleep and its health consequences, how poor sleep impacts exercise behavior, and how behavioral interventions such as exercise may reduce cardiometabolic disease risk through improved sleep. Dr. Kline also has a long-standing interest in studying the impact of sleep and circadian rhythms on athletic performance, and specifically how these factors may be used to optimize performance. He utilizes a wide variety of measurement techniques to assess sleep, including self-report questionnaire, diary, actigraphy, home-based portable monitoring, and laboratory-based polysomnography, and has addressed his research questions using a number of different approaches including laboratory-based randomized controlled trials (exercise and sleep apnea), archival analyses of RCTs (DREW, Sleep AHEAD) and epidemiologic datasets (SWAN), and observational surveys ('Sleep in America' poll).

Current Research:

Dr. Kline's research is currently supported by a Career Development Award from the NIH's National Heart, Lung, and Blood Institute. With this grant, he is studying the subclinical cardiovascular risk profile of the insomnia/short sleep phenotype and examining whether an augmented behavioral intervention would be feasible for this phenotype. For more information on this study, visit Dr. Kline is also conducting a study on the concordance between commercial sleep trackers (Fitbit, Garmin) and research-grade sleep trackers. If interested in learning more about the study or possibly serving as a participant, please contact Dr. Kline.


Dr. Kline is looking to accept graduate students with research interests in the bidirectional relationship between exercise and sleep for the 2017-2018 academic year. Please contact Dr. Kline for additional information about the lab and the application process.

If you are an undergraduate or MS student at the University of Pittsburgh who is interested in joining the lab as a volunteer research assistant, please contact Dr. Kline. The minimum commitment expected is 5-10 hours per week for at least 2 semesters. Students will gain hands-on experience at all stages of the research process.
