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:
