Organisms go through cycles of metabolic activity, driven by internal cues (circadian, circannual clocks) and physiologic/behavioral inputs (e.g. feeding/fasting, physical activity/rest). In addition, organisms face environmental challenges (physical, chemical or psychological stressors) that require continual adaptation of the pathways regulating metabolism. The goal of our research is to elucidate the regulatory and transcriptional mechanisms that integrate information and enable physiologic adaptations (particularly in response to changes in physical activity, environmental temperature, nutritional state), and that, when deregulated, contribute to metabolic disease.
