Chris Rayner is a Professor in the School of Medicine, University of Adelaide, and a gastroenterologist at the Royal Adelaide Hospital, South Australia. His major research interest concerns nutrient-gut interactions, including the regulation of gastrointestinal motility, with an emphasis on the role of upper gut function in diabetes. His work aims to develop an understanding of the mechanisms of glucose sensing and incretin hormone release in the gut, and how these can be manipulated for therapeutic gain. He has developed the concept of protein preloads, taken in advance of meals, to initiate gut feedback mechanisms that will lower subsequent postprandial glycaemia in type 2 diabetes. He is a Chief Investigator in an NHMRC Centre of Research Excellence in Translating Nutritional Science to Good Health, based at the University of Adelaide.
