  • My major research interest is 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. My major goal is to improve the quality of the evidence available upon which nutrition recommendations are based, particularly for the prevention and treatment of diabetes and cardiovascular disease.
