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.

This project will develop a smart bone healing gel to bridge fragments of bone defects leading to stem cell recruitment, reduced inflammation, and blood supply for fracture healing. The design of the smart bone healing gel is based on the structures and properties of functional tissue healing hematoma in wound healing.
This study aims to elucidate central pathways which can be manipulated to drive the storage of excess energy away from fat and instead directing it into the production of bone mass. Having identified leptin-responsive NPY neurons as important in the control of energy partitioning, we will focus on manipulating these neurons in the hypothalamus using innovative technology to alter body composition. This research has the potential to result in novel treatments for obesity and osteoporosis.
Sickle Cell Disease was the first molecular disease described in man, and is the most prevalent. In some African countries, India and the Middle East, up to 20% of the population carry the sickle gene mutation. In developing countries, 90% of children die before 5 years of age. In developed countries, patients suffer a lifetime of chronic pain and die ~20 years early. We will employ new gene editing approaches to repair the mutation or recruit fetal hemoglobin to cure SCD in human samples.
Genetic testing of IVF embryos promises to improve success but shows no effect of live-birth rates. Many embryos are mosaic: containing cells with correct and incorrect chromosome numbers. Current testing is an invasive biopsy which fails to diagnose how many cells are abnormal in the cells that develop into the baby. Here we will use imaging to determine the ratio of abnormal:normal cells resulting in a non-invasive diagnostic that will improve IVF success.
An Integrative Approach To Define And Attenuate Genomic Risk Of Coronary Artery Disease

Summary
One in four individuals that have a heart attack do not have traditional risk factors such as high blood cholesterol levels. This highlights the importance of 'family history', which we can now quantify as 'genetic risk'. These studies will determine (i) which genes are important in contributing to this genetic risk (ii) how these genes change biological pathways to increase risk and (iii) the effectiveness of modulating these biological pathways to reduce the risk of heart disease.
Harnessing Macrophage-derived Cytokine Signalling In Skeletal Muscle Regeneration
Funder
National Health and Medical Research Council
Funding Amount
$991,926.00
Summary
We propose to develop novel therapies and tissue engineering approaches for the treatment of muscle injury and wasting disorders using specific muscle stem cells called satellite cells. Our ultimate aim is to accelerate the development of safe, effective and affordable muscle stem cell-based therapies, in an attempt to lessen the disease burden of muscle wasting disorders. The approach will make use of the novel stem cell activating compounds and immune cells that we have identified.
Growth Factor Directed Developmental And Pathological Lymphangiogenesis

Funding Amount
$1,048,507.00
Summary
The formation of new lymphatic vessels occurs in normal development and in diseased tissues in cancer and cardiovascular disease. We have developed an understanding of how lymphatics form in development but we understand far less about how they form in disease. This project will apply multidisciplinary approaches, including genetics and computational biology, to compare how lymphatics form in development and disease. We hope to uncover new ways to manipulate this process for therapeutic gain.
Flaviviruses Must Come Of Age: Design Of Stable, Mature Particles By Structural Vaccinology

Funding Amount
$1,149,487.00
Summary
We have established a powerful toolset combining advanced structural biology and rapid virus engineering that allows us investigate the assembly of flaviviruses in novel ways. This project will integrate these approaches to investigate the role of new ligands that we have identified in the structure of medically-relevant flaviviruses including dengue virus and delineate a novel maturation path for flaviviruses, which will be used to design safer and more effective flavivirus vaccines.
Investigating The Consequences Of Dysregulated Lipogenesis In Cancer

Funding Amount
$600,647.00
Summary
Reprogramming of cellular metabolism is a hallmark of cancer. As such, there has been growing interest in developing strategies to exploit metabolism for therapeutic gain. Our ability to do this is dependent on a thorough understanding of the mechanisms by which dysregulation of cellular metabolism contributes to tumour progression. In this project, we seek to the investigate the fundamental mechanisms by which aberrant activation of lipid metabolism contributes to the tumourigenic process.
Exploring Non-canonical Roles For The Ribosomal RNA Genes Critical For Malignant Transformation And Cell Fate
Funder
National Health and Medical Research Council
Funding Amount
$1,972,669.00
Summary
Genes are encoded by linear DNA sequences, and whether they are expressed or silenced will depend on modifications and 3D interactions with other genomic regions. We aim to identify genes that interact with the a subnuclear body called the nucleolus during cancer development and differentiation. Understanding how these 3D genomic interactions are altered for the coordinated expression of a suite of genes may provide the basis for novel strategies to manipulate gene expression in disease.
