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.

Assessing a model of the physiological changes at arousal from sleep. Arousals from sleep are common in the elderly and have adverse consequences. This project will investigate a model of the changes in bodily processes (muscle, brain and cardiovascular activation) that occur when humans awaken from sleep.
Stress-sensing and cytoprotection in ageing and disease. This project aims to unravel the mechanisms responsible for age- and disease-related responses to heart attacks and the efficacy of therapeutic approaches, while deepening our understanding of a novel, potent protective modality effective in aged hearts. This program will provide valuable basic knowledge, leading to more efficacious therapies.
Breathing disturbances and reflexes in sleep and effects on sleep and daytime function. This project will investigate protective reflexes in sleep and the impact of breathing disturbances and frequent arousal on markers of brain functioning and health. This will also significantly advance the understanding of key mechanisms promoting unstable breathing in sleep and ill health and functioning from disturbed sleep.
New Materials for an Implantable Blood Pump. Rotary blood pumps are at the leading edge of heart assist technology. VentrAssist has developed an innovative rotary blood pump with a hydro-dynamically suspended impeller. Advanced surface modifications will enable the device to be fabricated from polymers; this will make the device light, more compatible with the human body and less costly to produce. Surface treatments and coatings will be applied using ion implantation, to impart the required ....New Materials for an Implantable Blood Pump.

Advanced surface modifications will enable the device to be fabricated from polymers; this will make the device light, more compatible with the human body and less costly to produce. Surface treatments and coatings will be applied using ion implantation, to impart the required dimensional stability, impermeability and wear resistance. Following sophisticated experiments of modified materials, the best candidates will be used in prototype devices, for final selection of the optimal materials for the new device.Read moreRead less
Determining how calcium regulates mitochondrial function in models of cardiomyopathy. Heart failure is the leading cause of death in Australia. This project will determine the mechanisms by which the failing heart is associated with disorganisation of the cell and poor energy supply so that interventions aimed at reducing the development of heart failure can be developed.
Novel computational tools for the analysis of sympathetic nervous system activity. This project will investigate electrical signals from the heart, resulting in novel tools for the assessment of sympathetic nervous system activity. The findings will contribute to advancing Australia's international leading position in health technology and improve community health.
Benefits of blood pressure lowering to combat cardiovascular disease. Stroke and heart attack are the commonest causes of death and adult disability. In Australia, approximately 50,000 people die from cardiovascular disease each year. This project will attempt to prevent stroke/heart attack and to improve quality of life by exploring better management of high blood pressure.
Electrophysiological and Anatomical Characterization of the Coronary Sinus Musculature and its Relationship to the Atria. This series of experiments will characterise the normal coronary sinus musculature and its connectivity to the atria of the heart and establish their electrical relationships. The underlying characteristics of the muscular connections will also be evaluated with a view to possible future manipulations of the system. Understanding normal heart impulse propagation is paramount ....Electrophysiological and Anatomical Characterization of the Coronary Sinus Musculature and its Relationship to the Atria. This series of experiments will characterise the normal coronary sinus musculature and its connectivity to the atria of the heart and establish their electrical relationships. The underlying characteristics of the muscular connections will also be evaluated with a view to possible future manipulations of the system. Understanding normal heart impulse propagation is paramount before we can understand and develop treatments for dealing with heart problems. This information will facilitate the development of techniques to treat and prevent heart rhythm disorders that are a common cause of morbidity in the community.Read moreRead less
Measurement and Prediction of Vulnerable Plaque Formation and Rupture. The major health problem of atherosclerosis, leading to large numbers of deaths from heart attacks and strokes worldwide, will be studied by a multidisciplinary team. Better understanding of how the disease evolves and its earlier detection will arise from this project, which will use synchrotron imaging and supercomputer prediction.

Summary
Neural regulation of immunity following brain injury. Following a brain injury, the brain tries to protect itself by blocking all inflammation. However, this renders the host with impaired immunity and increased risks to infections. The project aims to delineate the mechanisms behind this response, with the expected outcome of highlighting the important interplay between the nervous and immune system.
