A/Prof Richard L Young is a Senior Research Fellow in the Adelaide Medical School at The University of Adelaide, and 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, which links basic and clinician researchers in world-leading research in diabetes.A/Prof Young heads the Intestinal Sensing Group within the Nutrition, Diabetes and Gut Health Program of SAHMRI Lifelong Health. He investigates the intestinal taste system, which detects dietary sugars and low-calorie sweeteners and, in turn, controls how glucose is absorbed and disposed in the body. He has shown how this system is regulated in health, and its dysregulation in type 2 diabetes, critical illness and obesity. This NHMRC supported research is providing new knowledge of gut physiology and microbiology, with the potential to prevent, and better manage, type 2 diabetes and obesity.
We offer higher degree research projects that span interventional clinical research through to basic research with genetic and disease models. These projects aim to save lives in critical illnesses and can be tailored to the individual student. One-year Honours projects are also available in these areas. Students will be based in the west-end health precinct in SAHMRI, with clinical studies undertaken in the Adelaide University AHMS building (Clinical Research Facility, CRF).
Saving lives in critical illness by preserving cortisol targeting Blood levels of the carrier protein for cortisol fall in many patients with sepsis in a manner that predicts their death. Supplementing this protein in these patients may preserve its unique capacity to deliver the full benefits of cortisol's anti-inflammatory actions to injured tissues. Using our mouse model, which responds to sepsis in the same manner as patients, we aim to provide fundamental knowledge on the value of novel therapies to save lives. This is an exciting space and has the promise to deliver the first new therapy for sepsis management in decades. This project will involve clinical research in Adelaide University CRF and laboratory experiments in SAHMRI. Project start: Semester 1 and 2.
