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.

Fibroblast Growth Factors In The Development Of Forebrain Commissures
Funder
National Health and Medical Research Council
Funding Amount
$497,796.00
Summary
In order to function correctly the two hemispheres of the brain must communicate information. This communication occurs across large fibre tracts called commissures. There are three commissural projections in the forebrain; the corpus callosum, the hippocampal commissure and the anterior commissure. Here we investigate the development of these commissures and provide a comprehensive analysis of the role of several secreted, fibroblast growth factor proteins, in their development.
Pathogenesis And Therapeutic Modulation Of Aggressive Behaviour In A Mouse Model Of Autism Spectrum Disorder
Funder
National Health and Medical Research Council
Funding Amount
$583,015.00
Summary
This project focuses on understanding the causes of aggressive behaviour in mice that have a human gene mutation found in autism. Aggressive behaviour is common in autism patients and can have severe consequences on education and employment opportunities. These mice also show excess dampening of brain function (inhibition). This project will test if aggression in these mice is caused by altered inhibition.
How Can Trafficking Of The Tumour Suppressor PTEN Affect Normal And Abnormal Brain Development?

National Health and Medical Research Council
Funding Amount
$589,977.00
Summary
Autism is a complex neurodevelopmental disorder that is estimated to affect 1 in every 100 children. Currently we have no medical treatments to cure the disease. PTEN is a tumor suppressor that has been genetically linked to autism as it functions to inhibit cell growth that can result in abnormal brain development. In this grant we aim to study the location and function of PTEN and how failure of this system can result in neurodevelopmental diseases such as autism.
Gene-environment Interactions Modulating Cortical And Cognitive Dysfunction
Funder
National Health and Medical Research Council
Funding Amount
$618,300.00
Summary
A feature of many major brain disorders, including schizophrenia and dementia, is disruption of cognition. A key brain area impacted in such cognitive disorders is the prefrontal cortex. This project will use clinically translatable touchscreen to understand how this aspect of brain dysfunction causes abnormal cognition. We will investigate the mechanisms involved, using highly innovative approaches, which will contribute to the development of new treatments for such cognitive disorders.
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability
Funder
National Health and Medical Research Council
Funding Amount
$597,541.00
Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
Understanding the contribution of neuroinflammation in acute and chronic neural injury. A major focus of this project will be investigating the involvement of neuroinflammation in neural cell damage. It will explore how neuroinflammation contributes to this damage in both acute and chronic neuropathologies.
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.
Molecular And Cellular Mechanisms Of Axon Guidance In The Vertebrate Nervous System
Funder
National Health and Medical Research Council
Funding Amount
$330,735.00
Summary
There are, at least, two major obstacles that have to be overcome in the design of therapies to assist the repair of injured brain tissue. First, the nerve cells that are damaged have to be encouraged to regrow - typically this regrowth is inhibited in the brain; and second, this regrowth has to be directed so that the correct connections are re-established. This project will begin to unravel some of the mechanisms that nerve cells use to wire up together during development. This information can ....There are, at least, two major obstacles that have to be overcome in the design of therapies to assist the repair of injured brain tissue.

Discovery Early Career Researcher Award - Grant ID: DE130100323
Funder
Australian Research Council
Funding Amount
$375,000.00
Summary
The regulation by transcription factor phosphorylation upon the myelinating process. The project will investigate the novel molecular events that control the myelinating process, which is essential for normal nervous system function. Outcomes of this project may aid the development of novel interventions to improve control of demyelinating diseases, which represent a substantial socio-economic burden.
