Eligible to supervise Masters and PhD - email supervisor to discuss availability.

Richard L Young is an Associate Professor and Postgraduate and Honours Course Coordinator in the Adelaide Medical School at The University of Adelaide, and a Senior Research Fellow at the South Australian Health & Medical Research Institute (SAHMRI). He is a member of the Centre of Research Excellence in Translating Nutritional Science to Good Health (NHMRC 2013-2020) - an exceptional framework for linking basic and clinical researchers in Endocrinology and Gastroenterology.

He leads the Intestinal Nutrient Sensing Group within the SAHMRI Lifelong Health Theme in a program that investigates the intestinal sweet taste system with clinicians, basic scientists and industry. This system detects dietary sugars and low-calorie sweeteners and can, in turn, regulate the uptake and disposal of glucose in the body. He has shown how this system is regulated in healthy individuals and the consequences of its dysregulation in type 2 diabetes, critical illness and obesity. His laboratory research focuses on the vertical integration of signals from intestinal sweet taste receptors and gut bacteria to the whole body, and has the potential to yield new ways to prevent, and better manage, type 2 diabetes.

A/Prof Young also leads research in an ARC and industry collaboration investigating other gut hormone systems in humans. This research has the potential to usher in novel therapies for obesity and type 2 diabetes.

Research Projects

My group offers higher degree research projects that span interventional clinical research through to basic research with genetic and disease models. These projects are tailored to the individual and backed by research support from government and industry. Shorter honours projects are also available in these areas. Students will be based in the west-end health precinct at SAHMRI, while clinical studies involve research in the adjacent Royal Adelaide Hospital (RAH).

  • Title: Can blocking gut sweet sensing improve blood glucose control for patients with type 2 diabetes? Low-calorie sweeteners are increasingly consumed in the community, but we have shown that their dietary supplementation can worsen control of blood glucose in healthy subjects. Patients with type 2 diabetes may be at even higher risk of worsening blood glucose control due an existing defect in sweet sensing in the gut wall. This project will investigate whether blocking sweet sensing in the gut improves control of blood glucose in patients with type 2 diabetes. This project will involve clinical research in the RAH and laboratory experiments in SAHMRI. Project start: Semester 1 and 2.
  • Title: How does the human gut respond to low-calorie sweeteners? This project will establish the precise mechanisms that link sensing of low-calorie sweeteners in the gut wall and gut bacteria to signals that disrupt host control of blood glucose. This will involve functional and multi-omic experiments in human biopsy tissues and experiments examining gut bacteria in SAHMRI. Project start: Semester 1 and 2.
