  • Often with an emphasis in clinical nutrition, I have obtained peer review and non peer review grants (mostly Phase II and III pharmaceutically funded multicentre national and international studies) as Principal, Co-principal or Co-investigator. These studies have investigated the effects of various new drugs on diabetes control, hyperlipidemia and prevention and treatment of diabetes complications. I have been particularly interested in the nutritional management of diabetes with other colleagues in the Department (Jenkins, Wolever). We have promulgated the concept of the glycemic index of foods and the importance of meal frequency as therapeutic principles. We have promulgated the concept of the glycemic index of foods and the importance of meal frequencies as diabetic principles. Metabolic bone disease research, principally osteoporosis, revolves around phase II and III drug studies for the treatment of osteoporosis and other metabolic bone diseases. Much of this work is multinational, multicentre investigations, but I also conduct other epidemiologic and clinical studies in disorders of calcium metabolism and metabolic bone disease.
