Research Focus


My research focuses on developing artificial pancreas systems for type 1 diabetes. The artificial pancreas is a medical device that automatically regulates glucose levels for patients with type 1 diabetes. The artificial pancreas is composed of a glucose sensor, an infusion portable pump, and an advanced mathematical dosing algorithm that controls hormonal delivery based on the sensor readings. Using commercial pumps and sensors, my lab develops and clinically tests novel control algorithms that are the crux of the artificial pancreas. We also conduct clinical trials to assess different configurations of the artificial pancreas, the performance of the artificial pancreas during exercise and meals, and the performance of the artificial pancreas in special patient populations and during long-term use. As the artificial pancreas is considered the most promising therapy for type 1 diabetes, this work has great potential to improve patients’ quality of life.
