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.

Novel Epidemiological Methods To Infer The Causal Effects Of Risk Factors On Neuropsychiatric And Cardiovascular Disorders

Summary
Epidemiological studies, which associate risk factors and disease, are central in informing public health policy. Because causality is difficult to ascertain from these associations, public health interventions based on these findings are at some risk of failure. We propose to develop, extend and apply an innovative epidemiological approach, Mendelian randomization (MR) to resolve the causal relationship between risk factors and neuropsychiatric and cardiovascular disorders.
Regulation of neuronal cell death signalling for the treatment of neurodegenerative diseases. The progression of neurodegenerative diseases, such as Alzheimer's and motor neuron diseases, are often underpinned by neuronal cell death-signalling. This project aims to characterise molecules that regulate cell death signalling, thereby increasing our knowledge of how neuronal cell death can be inhibited.
New tools to activate and silence neural circuits. Many neurological disorders occur as a result of neuron cell death that is initiated by excessive levels of excitatory activity in central nervous system neurons. This project will develop and validate a new treatment for these disorders that involves silencing excessive neuronal activity using a safe, commonly prescribed drug.
The role of actin in driving bulk endocytosis in neurons and neurosecretory cells. Synaptic release of neurotransmitter is essential for neuronal communication. Following fusion, synaptic vesicle membrane is incorporated into the plasma membrane and retrieved by endocytosis to recover both lipids and essential vesicular proteins. The project will characterise how the actin cytoskeleton perform this function.
Novel pharmacological agents to target stroke-induced brain injury. There is a looming stroke epidemic in Australia. 72% of Australian stroke sufferers are over the age of 65 and whereas in 1997 only 12% of Australians were in that age group, by 2030 that number will have increased to 23%. There is an urgent need for novel therapies. This project will aid the development of a novel anti-stroke therapy.
Molecules and mechanisms regulating axonal degeneration and regeneration in Caenorhabditis elegans neurons. Understanding the molecular mechanisms underlying nerve degeneration and regeneration is essential to tackle and provide treatment for neurodegenerative diseases and injury of the nervous system. This project aims to discover, using a genetic approach and a simple animal model system, the molecules regulating these crucial biological processes.
The endosome at atomic resolution. The project seeks to improve understanding of intracellular transport. The transport of proteins is essential for controlling the interactions of a cell with its environment, and for regulating a huge number of cell signalling events. The retromer protein complex is a central mediator of intracellular trafficking in organelles called endosomes. It is vital for normal cell homeostasis in all eukaryotic organisms, and is an emerging target for treatment of human ....The endosome at atomic resolution.

The retromer protein complex is a central mediator of intracellular trafficking in organelles called endosomes. It is vital for normal cell homeostasis in all eukaryotic organisms, and is an emerging target for treatment of human neurodegenerative diseases. This project plans to use a combination of cutting-edge X-ray crystallographic and electron microscopy approaches to develop a multi-scale, pseudo-atomic structure of retromer and key regulatory proteins to understand how this multi-component protein machinery is assembled to control intracellular transport.Read moreRead less
AusDiab 3: Emerging Risk Factors For And Long-term Incidence Of Cardio-metabolic Diseases
Funder
National Health and Medical Research Council
Funding Amount
$2,616,397.00
Summary
This study will track 11,000 Australian adults over 12 years to determine how many develop diabetes, obesity, kidney and heart disease. The study will develop ways to best predict those who are going to develop these conditions before they have arisen, and will explore a range of novel risk factors to better understand these conditions.
Control of language production and its neural substrates. The ability of humans to say the right word at the right time is a critical, complex and poorly understood function. This research will determine the brain circuits responsible for language production and how this process is affected in Parkinson's disease.
Optimising Heart Disease Prevention And Management
Funder
National Health and Medical Research Council
Funding Amount
$4,647,175.00
Summary
As we become older and risk factors such as obesity become more common, our biggest contributor to death and disability, cardiovascular disease (including heart disease), will continue to exert an enormous burden on our health care system and society. We will extend our ground-breaking research on multidisciplinary teams to create new and innovative health care programs to optimise the prevention and management of new heart disease and chronic forms of heart disease.
