Research in my laboratory focuses on animal circadian clock and its control over organismal physiology. Besides being indispensable for the control of daily activities, such as the sleep-wake cycle, locomotor activity, hormone circulation and food intake, defects in circadian rhythms and clock genes have also been implicated in a wide range of human disorders, including chronic sleep orders, various forms of depression, metabolic syndromes, as well as susceptibility to cancer and drug and alcohol addiction. Using a combination of biochemical, molecular genetics, and proteomic approaches, our goal is to dissect the molecular network and cellular mechanisms that control the circadian oscillator in animals, and investigate how this molecular oscillator interact with the environment and cellular metabolism to drive rhythms of physiology and behavior.
