Research Synopsis

My major research interest has been to understand the physiological effects of dietary carbohydrates (sugars, starch and dietary fiber) on glucose and lipid metabolism and energy balance in humans, and to translate the knowledge gained into practical/clinical use.  However, I will be retiring in 2019 and have no plans to start any new research projects at the University.
