As a researcher with significant training in exercise science and sleep medicine, Dr. Kline's research focuses on three central topics: (1) the use of physical activity as a nonpharmacologic/behavioral treatment for disturbed sleep and its health consequences; (2) how poor sleep impacts exercise behavior; and (3) 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, archival analyses of randomized trials and epidemiologic datasets, and observational surveys.

Dr. Kline's research is currently supported by three grants from the National Heart, Lung, and Blood Institute of the NIH:
- A Career Development Award in which 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 (K23HL118318);
- A small grant that supplements the Career Development Award by studying the subclinical cardiovascular risk profile of adults with isolated short sleep (but no insomnia) and isolated insomnia (but 6+ hr sleep duration) (R01HL148357);
- An ancillary study that adds sleep assessment to Dr. Bethany Barone Gibbs' RESET BP clinical trial, allowing us to examine the impact of sedentary behavior reduction on sleep and whether poor sleep blunts the cardiometabolic health benefits of sedentary behavior reduction (R01HL147610).
In addition, Dr. Kline has funding from the University of Pittsburgh to address whether acute exercise impacts obstructive sleep apnea (OSA) severity and examine whether evening exercise reduces OSA severity to a greater extent than morning exercise in comparison with a sedentary control condition.
To learn more about any of these studies, please contact Dr. Kline.
Dr. Kline is looking to accept a PhD student or postdoc with research interests in the bidirectional relationship between exercise and sleep for a Fall 2020 start. Please contact Dr. Kline for additional information about the research group and the application process.
If you are an undergraduate or MS student at the University of Pittsburgh who is interested in joining the group 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, including sleep assessment methodology (e.g., actigraphy, polysomnography).
