Research & Publications
The overall goal of our research projects is to elucidate the neural mechanisms underlying the controls of food intake and energy expenditure and in the regulation of glucose homeostasis. Currently, we have four main projects: (1) to decipher the hypothalamic-brainstem systems in controlling ingestive behavior, (2) to tease out the neural signaling pathways in modulating fat browning and brown fat thermogenesis, (3) to identify neural circuits and molecules involved in the hypothalamic regulation of hepatic glucose production and insulin sensitivity, and (4) to unravel the neural mechanisms of feeding effects of exercise such as exercise-induced anorexia. We conduct researches using both in vivo animal and in vitro cell culture models with various techniques at genetic, molecular, cellular, neurochemical, pharmacological and behavioral levels. Overall, we aim to explore potential molecules and/or approaches for the prevention and treatment of disordered feeding behaviors, obesity and associated comorbidities.
Currently, we are seeking self-motivated and talented young scientists to join our research team.
