Description of Research

Summary Statement of Research Interests
Our efforts are directed at understanding the mechanisms by which the body detects low blood sugar (hypoglycemia) and how it integrates that information to generate corrective responses. We are particularly interested in peripheral glucose sensors located in the gut, which play a prominent role in detecting small or slow changes in blood glucose. We have characterized various aspects of these sensory neurons, i.e. type, origin, metabolism, and have begun to exam their role in pathological states, e.g. diabetes. In collaboration with Dr. Alan Watts (Neuroscience) we are also examining the interaction between these peripheral glucose sensors and those located in the brain.
