Circadian systems drive daily oscillations in physiology in organisms from bacteria to humans. These oscillations are coordinated by specific changes in environmental cues, the most important of which is light. In animals, circadian regulation of brain function creates rhythmic patterns in behaviors like sleep. Circadian dysregulation is a common feature of many human diseases and environmental causes of circadian disruption increase susceptibility to many diseases including cancer. Importantly, circadian disruption is also commonly seen in hospitalized patients, which could have negative effects on health outcomes. Understanding the basic biology of circadian-regulatory systems and their physiological functions is essential for identifying the impact of circadian rhythms on human health. This dissertation describes a body of work using the fruit fly Drosophila melanogaster to better understand circadian regulation and its impact on behavior and physiology.
