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.

Neural Control Of Human Respiratory Muscles In Health And Disease
Funder
National Health and Medical Research Council
Funding Amount
$450,132.00
Summary
This research examines how human inspiratory muscles that ‘pump’ air into the lungs are controlled in health and disease. We will study the interaction between automatic and voluntary control of breathing, about which very little is known. The control of breathing in patients who breathe against an inspiratory load (eg. asthma) and mechanically ventilated patients will be a focus of this research. Outcomes include better understanding of the control of breathing and improved patient care.
Mucous In Heterogeneous And Progressive Early Cystic Fibrosis Lung Disease
Funder
National Health and Medical Research Council
Funding Amount
$347,948.00
Summary
Cystic fibrosis (CF) is the most common genetically acquired, life-shortening chronic illness affecting young Australians today. Individuals with CF have a reduced ability to clear mucous from the airways resulting in respiratory infections and inflammation. This project will quantify the biochemical and biophysical properties of mucous in young children with CF to generate novel insights into the pathogenesis of early disease, biomarkers of disease progression and therapeutic targets.
Monitoring Oxygen Saturation And Heart Rate In The Early Post Natal Period
Funder
National Health and Medical Research Council
Funding Amount
$344,150.00
Summary
In recent years experts have suggested that even a brief exposure to high oxygen concentrations during delivery room (DR) resuscitation is harmful. This has led to a change in our national DR resuscitation guidelines which now advise that 21% oxygen should be considered rather than 100% oxygen for infants of all gestational ages. I aim to develop evidence based guidelines for the use of pulse oximetry in the DR and early post natal period.
A novel sensory neural circuit has been identified innervating the airways and lungs. The anatomical organisation of this circuit has been described to some extent in previous studies, however there is a significant gap in knowledge with respect to its functional importance. This project will develop methods to address this knowledge gap and in doing so the project will firstly describe how this circuit controls breathing under normal conditions and secondly how this becomes dysregulated during
Improving Outcomes In Obstructive Sleep Apnoea Through Individualised Treatment Of Physiological Abnormalities
Funder
National Health and Medical Research Council
Funding Amount
$340,891.00
Summary
The most common treatment for obstructive sleep apnoea, continuous positive airway pressure, is only accepted by ~50% of patients. Individualised treatment options are urgently needed. In order to predict who will benefit from the common alternative therapies, my research will show how, upper airway surgery improves obstructive sleep apnoea at an individual level and develop tools that will help clinicians select patients for these therapies.
Translation Of Abdominal Functional Electrical Stimulation From A Research Tool To Clinical Practice
Funder
National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
People with a spinal cord injury to the neck are often unable to move their arms and legs, a condition known as tetraplegia. Tetraplegics are also unable to use their abdominal muscles, reducing breathing and bowel function. This project will use electrical pulses to make their abdominal muscles contract, improving breathing and bowel function. The results will be used to develop a program that can be used in all hospitals, reducing illness in tetraplegia and saving the health service money.
Regulation Of Pulmonary Responsiveness By Chronic Mechanical Strain And Its Role In Obstructive Lung Disease
Funder
National Health and Medical Research Council
Funding Amount
$287,321.00
Summary
The pressures required to breathe place a continuous but varying mechanical strain on airway passages and lung tissue. This mechanical strain may protect the airway from collapsing, however, this protection is deficient in lung diseases such as asthma. This project considers the possibility that abnormal mechanical strain occurring in lung disease predisposes the individual to debilitating and potentially life-threatening airflow obstruction.
Improving Lung Health Of Indigenous Children, Through Identifying Interventional Targets From Long Term Follow-up Studies And Preventive Strategies
Funder
National Health and Medical Research Council
Funding Amount
$314,644.00
Summary
Long term consequences of respiratory disease among Indigenous children are a public health issue. Studies included in this research program will provide new data and broaden our understanding on clinical predictors that significantly impact on lung health in Indigenous children. The studies will also direct future interventions and management pathways. This research will also contribute to improved asthma management, prevent uptake of smoking contributing to an overall improvement in health.
I am a physiologist investigating how the brain controls balance and movement. Many neurological disorders cause unsteady balance and problems with movement, and consequently a poor quality of life. I study people with disorders of the sensory and movement processing areas of the brain to discover how the brain combines different sensory information to control balance. This work will improve understanding of human balance and movement, and lead to new clinical techniques for assessment and treat ....I am a physiologist investigating how the brain controls balance and movement.
