Circadian Rhythm and Exercise Research Lab

Division of Kinesiology and Health

The circadian clock plays a key role in coordinating many biological processes, from behaviors to cellular metabolism and mitosis. Disruption of circadian rhythms can increase susceptibility to multiple diseases (cancer, cardiovascular disease, etc.); however, it is surprising that little is known about the consequences of chronic circadian misalignment causing disease.

Studies suggest that frequent jet lag or shifts of daily rhythms as a result of rotating shift work can lead to many deleterious health outcomes. However, voluntary physical activity has been positively correlated with decreases in cardiovascular disease, obesity, type II diabetes and some forms of cancer.

Therefore, my underlining scientific objective is to use physical activity interventions as a tool to mitigate or delay the harmful diseases that can develop from chronic circadian misalignment.

Research Focus

This lab focuses on the underlying mechanisms of how physical activity interventions can reset peripheral and/or central clocks that become misaligned due to chronic circadian disruption (i.e. working the night shift, frequent jet lag, or the normal aging process).
