• Biography/ Background

  A/Prof Richard L Young is a Senior Research Fellow within the Adelaide School of Medicine, University of Adelaide, based at the South Australian Health & Medical Research Institute (SAHMRI). He is a member of the NHMRC Centre of Research Excellence in Translating Nutritional Science to Good Health (2013-17, University of Adelaide), an exceptional framework for linkage between basic and clinical researchers in endocrinology and gastroenterology. 

  Following doctoral studies at the Department of Medicine, University of Melbourne (Prof Bill Louis, Prof Andrew Gundlach) he undertook postdoctoral research within the Nerve-Gut Research Laboratory in Adelaide (Prof John Dent, Prof Ashley Blackshaw) in an industry collaboration investigating strategies to inhibit gastroesophageal reflux (2000-7). He pioneered advanced anatomical and in vivo electrophysiology techniques to investigate vagus nerve circuitry in the brainstem, many of which remain unique. His research informed strategic decisions within industry, including two full-scale drug development programs leading to the clinical deployment of an anti-reflux drug. His published works in this area revealed the anatomy and neurophysiology of central gastric vagal circuits, and a novel vagal innervation of the crural diaphragm.

  He has now established an independent research line with NHMRC and Diabetes Australia support focussed on the form and function of the intestinal sweet taste system. This system senses intestinal glucose, and in response may regulate the release of gut hormones and control glucose absorption. His research has revealed regulation of this system by luminal and blood glucose, and has documented dysregulation in human diabetes, critical illness and obesity. This knowledge has attracted collaborators from basic and clinical science backgrounds, and from industry. He has secured unique access to genetic and disease models and to a range of human tissue to broaden his enquiry. Limited knowledge exists on the vertical integration of glucose signals from the intestinal lumen, and this translational research in this emerging area is a distinctive strength.

  A/Prof Young also is engaged in ARC and industry-supported collaborative research investigating the peripheral serotonin system in humans. This system has novel and emerging roles in metabolic control, and is an exciting prospect for future novel therapies for obesity and Type 2 diabetes.
