The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Vitamin D, Bone Loss, Fracture And Mortality Outcome
Funder
National Health and Medical Research Council
Funding Amount
$408,736.00
Summary
Vitamin D most commonly from sunlight exposure is considered an important determinant of health, including the liability to falls and fractures; not only in the elderly but in adulthood in general. This study aims to distinguish if low vitamin D levels cause adverse health outcomes or relate to ill health, limited sunlight exposure and nutritional change. Only if low vitamin D level is causative of ill health does replacement make good public health sense.
Non-invasive Detection Of Hypoglycaemia In People With Diabetes Using Brain Wave Activity
Funder
National Health and Medical Research Council
Funding Amount
$330,447.00
Summary
Hypoglycaemia remains a major cause of morbidity and mortality in people with both type 1 diabetes and type 2 diabetes who require insulin therapy. Current treatments for nocturnal hypoglycaemia are usually ineffective. Combining brain wave recording and artificial intelligence, we will identify the changes that precipitate an episode of hypoglycaemia allowing the development of a non-invasive device to prevent or alleviate these fearful and potentially life-threatening events.
Deciphering How TCR Affinity Regulates CD4 T Cell Help In Immunity And Autoimmunity
Funder
National Health and Medical Research Council
Funding Amount
$850,885.00
Summary
Immune responses require the coordinated interaction and cross-talk between two types of white blood cells known as CD4 and CD8 T cells. A dysregulated interaction between these cells could be the cause of autoimmune and persistent infections by pathogens leading to chronic diseases. The aim of this proposal is to provide a deeper understanding of CD4/CD8 T cell interactions to improve immune outcomes in many chronic diseases in which interaction between these two immune cells is critical.
Investigating The Link Between Oxidative Stress And Biomechanical Integrin Activation In Diabetes

Funding Amount
$653,742.00
Summary
Diabetes represents a serious healthcare problem globally. A large proportion of deaths associated with diabetes can be attributed to the development of blood clots in the circulation of the heart and brain (heart attack/stroke). The blood clotting mechanism is ‘hyperactive’ in diabetes, although the reason for this is not well defined. In this proposal we will investigate a new mechanism promoting blood clots, and will investigate innovative approaches to reduce this clotting mechanism.
Do Synaptic-like Mechanisms Control Insulin Secretion?
Funder
National Health and Medical Research Council
Funding Amount
$593,235.00
Summary
An estimated 415 million people world-wide were diagnosed with diabetes in 2015. One of the causal factors in disease is the dysregulation of insulin secretion. We have developed new techniques to study insulin secretion that has led us to propose a new model for secretory control. This proposal sets out experiments to critically test this model. The outcomes could have wide-reaching impact on understanding and for future treatment and prevention of the diabetes.
The Treatment Of BOoking Gestational Diabetes Mellitus Study: The TOBOGM Study
Funder
National Health and Medical Research Council
Funding Amount
$2,197,280.00
Summary
Gestational diabetes mellitus (GDM) related pregnancy complications are reduced with treatment from 24-28 weeks pregnant. Many women are diagnosed/treated earlier without evidence of benefit and possible risk of harm. In TOBOGM women under 20 weeks pregnant with mildly raised blood glucose will be allocated by chance to either immediate treatment, or awaiting a repeat diabetes test at 24-28 weeks pregnant to decide treatment. Harmful and beneficial effects on mother and baby will be compared.
How Does Exercise Ameliorate Programming Of Metabolic Dysfunction In Offspring Of Obese Mothers?
Funder
National Health and Medical Research Council
Funding Amount
$524,121.00
Summary
Obesity is a worldwide disease, reflecting an interaction between our environment (diet, physical activity) and genes. We know that a mother's unhealthy diet can predispose offspring to diabetes, and exercise can improve this, but the underlying mechanisms are poorly understood. Here we will examine how exercise can benefit offspring of obese mothers, and test a drug that mimics the effects of exercise. The proposed research will provide insight into ways of reducing the obesity epidemic.
How Does Paternal Obesity Influence Offspring Glucose Tolerance?
Funder
National Health and Medical Research Council
Funding Amount
$503,398.00
Summary
Obesity and diabetes are closely related to these conditions in either parent, but how the father contributes is unclear. We have shown that normal females mated with obese fathers consuming high fat diet, produce offspring who develop glucose intolerance and impaired insulin secretion. This work will examine the mechanisms underlying this effect in the rat, testing a novel role for environmental factors in the father on disease in offspring that may be relevant to the growing obesity epidemic.
Understanding Sphingolipid Mediators Of Insulin Resistance
Funder

Funding Amount
$643,447.00
Summary
Sphingolipids are a class of lipid metabolites that have a variety of functions within cells. It has been known for some time that an accumulation of excess lipid, including certain sphingolipids, can adversely impact insulin action and glucose metabolism in cells. In this project we will a combination of strategies to test the hypothesis that the sphingolipid profile can be manipulated to have favourable effects on metabolism.
The Structure And Function Of The Apical Domain In Insulin Secreting Beta Cells.
Funder
National Health and Medical Research Council
Funding Amount
$571,741.00
Summary
Loss of control of insulin secretion is causal in diabetes and therefore its understanding is a key goal to shed light on the disease. We have recently identified a new domain in the insulin secreting cells, called the apical domain. This proposal will define the role of this apical domain in controlling insulin secretion. The outcomes could provide new insights into how diabetes develops and new targets for therapies.
