Professional Statement
The goal of my research is to identify the novel neural circuits, neurotransmitters and intra-neuronal signals that are critical for coordinated control of body weight, feeding behavior, glucose balance and blood pressure. The critical approach that makes the cornerstone of my laboratory efforts is targeted gene manipulation in mice. We use the Cre-loxP and/or Flpe-frt strategy to achieve tissue or cell-specific gene deletion or re-activation in functional animals. This genetic approach is supplemented by optogenetics, neuroanatomy, electrophysiology, systemic physiology, biochemistry, molecular biology and cell-based techniques.
Ongoing projects in the laboratory include:
(1) Sex differences in central control of body weight and glucose balance.
(2) External and intrinsic signals regulating activities of melanocortin neurons in the context obesity and diabetes.
(3) The 5-HT neural circuits and feeding behaviors.
(4) Brain estrogenic actions and blood pressure.
