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.

A Randomised Controlled Trial Of Low-dose Ketamine In Youth With Severe Depression And Elevated Suicide Risk
Funder
National Health and Medical Research Council
Funding Amount
$2,232,757.00
Summary
Recent research has shown that a single injection of low-dose ketamine has powerful, though short-lived, antidepressant effects. Effective treatments are urgently needed for young people with severe depression. This will be the first controlled study to test whether repeated doses of ketamine, given over 4 weeks, is effective for young patients.
The Burden Of Late Preterm Birth On Brain Development And 2 Year Outcomes – A Prospective, Longitudinal Cohort Study
Funder
National Health and Medical Research Council
Funding Amount
$838,690.00
Summary
80% of preterm babies are born from 32-36 weeks’ gestation, and are late preterm (LPT). LPT children have more learning problems, but why this occurs is unknown. This study aims to understand the effect of LPT birth on brain development. We will do brain scans at term and assess development at 2 years of age of 200 LPT and 200 full-term children. We expect LPT babies will have subtle alterations in brain development compared with term controls which will be associated with delayed development.
A Selective Prevention Trial Using Novel Pharmacotherapies In An Older Age Cohort At Risk For Depression
Funder
National Health and Medical Research Council
Funding Amount
$975,259.00
Summary
The study will examine whether omega-3 fatty acids or antidepressants prevent the onset of depression in a group of older community participants who have previously been identified as being "at risk" of depression. The study will incorporate sophisticated brain scanning methods, as well as tests of brain functioning to determine acute brain changes, reduction in cognitive decline and prevention of depression over a one-year period.
An MRI Study Of Emotional Processing Deficits In Childhood
Funder
National Health and Medical Research Council
Funding Amount
$578,985.00
Summary
The ability to recognise and process emotions in other people is fundamental to healthy social interactions. Conduct disordered children with callous and unemotional traits have difficulty recognizing fearful expressions, possibly due to lack of attention to cues such as facial expressions that healthy people naturally attend to. This study will use neuroimaging to determine if brain activity changes to look more like typically developing children if their gaze is redirected to facial cues of em ....The ability to recognise and process emotions in other people is fundamental to healthy social interactions.

A Dimensional Approach To Mapping The Risk Mechanisms Of Mental Illness
Funder
National Health and Medical Research Council
Funding Amount
$1,677,975.00
Summary
There is ongoing debate about whether current definitions of mental disorders are accurate. We will use statistical techniques to identify the core dimensions of liability for mental illness, and map how genes and brain organization drive differences between people along each dimension.
Optimising Radiation Therapy Delivery For Cancer Patients Using Daily Image Guidance To Maximize Cure And Reduce Normal Tissue Side Effects
Funder
National Health and Medical Research Council
Funding Amount
$510,968.00
Summary
When using radiotherapy to kill tumours, the radiation beams need to be targeted at the tumour, plus a margin of error around it to ensure that it receives sufficient dose despite uncertainties in its exact location relative to reference points used for beam alignment. Advanced statistical modelling techniques applied to data collected from patients will be used to determine the optimal margin width for individual patients to maximise cancer cure while minimising normal tissue side effects.
The Role Of Nuclear Architecture In The DNA Damage Response
Funder
National Health and Medical Research Council
Funding Amount
$561,966.00
Summary
The goal of the proposed research is to understand how dynamic changes to the chromatin genome packaging network, interact with the DNA damage response and gene expression machinery, to repair damaged DNA and the impact this has on cancer biology. To do so we are combining cutting edge molecular biology techniques with innovative novel microscopy methods developed by our research team, that far exceed the spatiotemporal resolution currently used to study chromatin biology.
Improving Patient Safety In Radiation Therapy With The Watchdog Real-time Treatment Delivery Verification System
Funder
National Health and Medical Research Council
Funding Amount
$593,742.00
Summary
Radiation therapy is a highly effective cancer treatment with extremely high doses delivered using very complex treatment machines. Unfortunately errors have occurred resulting in cases of patient death and mistreatment. We have developed a novel method to assess the treatment delivery in real-time to prevent errors. The method uses imaging devices that are already present on the treatment machine meaning that this method could have a major impact on patient safety in modern radiation therapy.
PARP And PI3K Inhibition In Pancreatic Cancer: Intravital Insights And ‘fine-tune’ Priming Using AKT And Single/double-strand DNA Break Biosensor Mice.
Funder
National Health and Medical Research Council
Funding Amount
$760,505.00
Summary
Inefficient drug response in solid tumour tissue is often a limiting factor in the clinical effectiveness of cancer therapies. Using cutting-edge imaging technology and 3D models that mimic the disease, we can map areas of poor drug response within distinct regions of tumours with chemotherapy. Here, we will shift factors limiting efficient drug targeting in these areas to improve the encouraging anti-cancer profile of PI3K and DNA repair inhibitors in pancreatic cancer.
