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.

APLP2: A Neuroprotective Receptor For Acute Brain Injury
Funder
National Health and Medical Research Council
Funding Amount
$648,739.00
Summary
Traumatic brain injury (TBI) is the major cause of deaths in Australians under 45 years of age. We have shown that the amyloid precursor protein (APP) is protective in models of TBI. To understand how APP is neuroprotective we have isolated APP binding proteins and identified the amyloid precursor-like protein 2 (APLP2) molecule as a strong candidate for the APP-neuroprotective receptor. This grant will investigate the interaction between APP and APLP2 as a novel neuroprotective pathway in TBI.
Emotion Regulation After Brain Injury: New Approaches To Remediation
Funder
National Health and Medical Research Council
Funding Amount
$922,662.00
Summary
Traumatic brain injuries, often from motor vehicle accidents, devastate the lives of thousands of young Australians each year and can lead to changes in personality and emotional regulation. Frontal lobe damage may cause apathy, withdrawal and loss of motivation or a loss of control leading to poor inhibition and anger outbursts. In this project we trial some experimental approaches to improving emotion regulation including biofeedback, self-control therapy and direct cortical stimulation.
Proteases And Protease-inhibitor Complexes As Modulators Of Traumatic Brain Injury Severity

Funding Amount
$613,311.00
Summary
Traumatic brain injury (TBI) is a significant cause of mortality and morbidity in Australia, affecting approximately 21,800 Australians annually. A large number of survivors have permanent neurological deficits, causing adverse effects on lifestyle and family relationships and placing a significant burden on the health system. In this project we will address a novel means to improve TBI outcome by targeting two linked enzyme systems that together have been shown to be deleterious in this conditi ....Traumatic brain injury (TBI) is a significant cause of mortality and morbidity in Australia, affecting approximately 21,800 Australians annually.

Social Functioning In Early Primary School Following Traumatic Brain Injury Prior To Age Three: The Contribution Of Cognitive, Environmental And Neurological Factors
Funder
National Health and Medical Research Council
Funding Amount
$394,501.00
Summary
Children of preschool age and older demonstrate social problems after a traumatic brain injury (TBI). What effect a TBI has on the social function of young children (before 3 years) is currently unknown but is thought that these children have more problems than older children do. This study will look at how a TBI impacts on the social function of young children and the role of cognition and brain development in social function will also be explored.
Executive Dysfunction And Brain Development In Very Preterm 13-year-olds - A Longitudinal MRI Study.
Funder
National Health and Medical Research Council
Funding Amount
$738,656.00
Summary
An area of concern for very preterm children is executive function (i.e. skills used for problem solving), which is related to educational problems, behavioural issues and social difficulties. In very preterm children this study will 1) determine if executive function problems remain stable, worsen, or improve with age; 2) look for markers for these problems from infant brain scans; and 3) examine how executive function difficulties are related to brain re-organisation.
Identifying The Neural Signature Of Persistent Pain
Funder
National Health and Medical Research Council
Funding Amount
$547,094.00
Summary
Chronic pain affects over 20% of Australians. Despite its high prevalence, it is relativly resistant to current treatment regimes and part of the reason behind our inadequate ability to provide satisfactory pain relief is due to our limited understanding of the pathophysiology that underlies this condition. This proposal will develop a novel understanding of the central neuroplastic changes associated with chronic pain and the role that these changes play in the maintenance of these conditions.
The Transition From Hospital To Home: A Longitudinal Study Of Indigenous Traumatic Brain Injury (TBI)
Funder
National Health and Medical Research Council
Funding Amount
$888,851.00
Summary
The six-month transition period following discharge from hospital after a traumatic brain injury (TBI) is critical. During the transition period, key sentinel events may influence health and wellbeing. The research will investigate key sentinel events during the transition period following TBI in the first longitudinal study with Indigenous Australians. This study will provide the first systematic evidence regarding the support Indigenous Australians need to successfully transition back into the
Preclinical Evaluation Of The Novel Therapeutic Compound APP96-110 In An Ovine Model Of Traumatic Brain Injury
Funder
National Health and Medical Research Council
Funding Amount
$874,734.00
Summary
Traumatic brain injury (TBI) is a significant cause of death and disability, and yet there are currently no effective treatments to improve outcome following such an insult. Our laboratory has developed a novel therapeutic compound, by identifying an endogenous neuroprotective molecule, in the amyloid precursor protein and then identifying the active site and modifying it to improve its efficacy. We will be testing this compound in our sheep model of TBI.
Biomaterials For The Direct Reprograming Of Reactive Astrocytes Into Functional Neurons
Funder
National Health and Medical Research Council
Funding Amount
$630,500.00
Summary
We will employ peptide inspired hydrogel nanoscaffolds that can be injected into a brain lesion as a single injection to provide chemical and physical support for the surrounding cells. We will utilize various modifications to these materials to reprogram inflammatory cells into neurons, whilst also promoting the survival, maintenance and growth of existing neurons to encourage repair.
The Modulation Of Neuronal Activity By Inter-cortical Sensory Input
Funder
National Health and Medical Research Council
Funding Amount
$638,771.00
Summary
For any given behaviour, the brain must merge information from all different sensory systems to generate a coherent representation of the external world. How this is achieved is largely unknown and is the basis of this research proposal. Here, using cutting edge recording techniques, the activity of brain cells within the cortex will be measured during the activation of multiple sensory systems. This research will provide insight into therapeutic approaches to local brain damage.
