Education:

• BA, Sports Science, Malone College (Canton, Ohio), 2002
• MS, Exercise Science, University of South Carolina (Columbia, SC), 2005
• PhD, Exercise Science, University of South Carolina (Columbia, SC), 2011
• Postdoctoral Fellowship, Translational Research Training in Sleep Medicine T32, University of Pittsburgh (Pittsburgh, PA), 2010-2013

Research Interests:

With undergraduate and graduate training in exercise science and postdoctoral training in sleep medicine, Dr. Kline is uniquely positioned to study the bidirectional relationship between physical activity and sleep. His research interests focus on the utility of exercise in the management of sleep disorders, the cardiometabolic consequences of poor sleep, and how exercise may reduce cardiometabolic risk via improvement of sleep quality. Currently, he is supported by a K23 Career Development Award through the NHLBI.

Current Research Funding:

• K23 HL118318: A novel risk factor for cardiovascular disease: The insomnia-short sleep phenotype, 2014-2018 NIH RePORTER link  BAD LINK FOR NIH REPORTER
