Research Summary

My research focuses on the application of new technologies to the treatment of diabetes. As part of my collaborations within the Diabetes Research in Children Network (DirecNet) and the Juvenile Diabetes Research Foundation Artificial Pancreas Project, I have been studying the safety, accuracy, and effectiveness of continuous glucose sensors to improve diabetes therapy, as well as investigating basic physiological questions of hypoglycemia counter-regulation. My main focus now is on the development of a so-called "artificial pancreas", in which an insulin pump automatically delivers the appropriate amount of insulin at any given time based upon receiving information from glucose sensor devices. I am also collaborating with several other pediatric endocrinologists and neuroimaging specialists to deterimne the effects of childhood diabetes on brain growth and function in children diagnosed with diabetes at a young age.
