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.

Haematopoietic Stem Cells From Human Pluripotent Stem Cells: The Future Of Bone Marrow Transplantation
Funder
National Health and Medical Research Council
Funding Amount
$763,845.00
Summary
Blood stem cell transplantation is a vital therapy for patients with leukaemia following chemotherapy or for patients with bone marrow failure. Because many patients lack a donor, there is a need for an alternate source of stem cells. My laboratory will make blood stem cells from human pluripotent stem cells that will treat patients needing a transplant and will be a useful research tool to help us to understand what goes wrong in the blood system in a range of illnesses.
Niche Regulation Of Normal And Malignant Stem Cells

Funding Amount
$622,655.00
Summary
Hematopoietic stem cells (HSC) reside in the bone marrow (BM) and make all the cells of the blood system. We study molecules in the BM regulating normal HSC to helping them survive chemotherapy. This means cancer patients should suffer less side-effects from their therapy. Some of these molecule also help leukaemia stem cells (LSC) resist chemotherapy. Inhibitors may a) reduce patient mortality caused by chemotherapy and b) sensitise LSC to chemotherapy enabling long-term cure.
Stem Cell Niches: Biology And Therapeutic Applications

Funding Amount
$640,210.00
Summary
This research aims to identify how stem cells are regulated in the body in order to improve therapies for blood disorders and abnormal bone formation after severe traumas. Targeting molecules that deregulate stem cells will lead to improved treatments for diseases with outcomes including improved treatments for blood stem cell transplantation, improved therapy in cancer patients and reduced complications of spinal cord injuries.
The Roles Of Retinoic Acid Receptors In Regulating Haemopoiesis And Bone

Funding Amount
$601,484.00
Summary
My research has shown that vitamin A is very important to the normal function of blood and bone cells. I will further explore the uses of vitamin A products to improve the treatment of patients with a range of different blood and bone diseases. These studies may lead to better treatments of patients with a wide range of blood cell diseases. It may also reveal better treatments for patients with bone diseases such as cancer and osteoporosis.
Regulation Of Normal And Malignant Haematopoiesis By The Bone Marrow Environment

Summary
This project will identify factors within the bone marrow that regulate blood and immune cell formation. These include oxygenation and novel proteins identified in the applicant’s laboratory. How these factors from the bone marrow influence the behaviour of normal blood forming cells (called haematopoietic stem cells), and the progression of leukaemia and the response of leukaemia to chemotherapy treatments will be investigated. New drugs that interfere with these new factors will be tested for ....This project will identify factors within the bone marrow that regulate blood and immune cell formation.

Regenerating The Kidney Using An Understanding Of Normal Development
Funder

Funding Amount
$951,005.00
Summary
In Australia, chronic kidney disease costs >$1 billion per annum, however treatment options for kidney failure have not changed for >50 years. Dialysis reduces quality of life and lifespan while only 1 in 4 patients receives a transplant. Using our understanding of normal kidney formation, this study will generate kidney tissue from human stem cells to better understand inherited kidney diseases and develop novel regenerative therapies for the treatment of end stage kidney disease.
Assessment Of The Properties Of Mesenchymal Stem Cells And Their Role In Skeletal Tissue Repair And Disease
Funder
National Health and Medical Research Council
Funding Amount
$751,854.00
Summary
There is currently a steady increase in surgical intervention and rehabilitation therapy for bone related fractures due to trauma or osteoporosis as a consequence of an aging population. Bone regeneration involves the coordinated participation of skeletal precursor cells, blood vessels and immune cells recruited from the surrounding tissues. This proposal examines the mechanisms mediating the maintenance and recruitment of skeletal precursor cells to sites of bone damage.
The cell types of the blood, such as red and white blood cells, are produced in the bone marrow from a rare stem cell. The stem cell uses a handful of important master-regulatory genes that act in a hierarchy to promote the blood cell differentiation process. This research aims to understand how these master-regulators function in isolation and together in producing the white blood cells that are required for our immune response to microbes, vaccination and to prevent cancer.
Trace Element Regulation In Neurological Disease: From Molecular Pathogenesis To Translational Impact.
Funder
National Health and Medical Research Council
Funding Amount
$631,370.00
Summary
Neurodegenerative diseases such as dementia and motor neuron disease are a major health burden for Australia and new approaches to treatment are urgently required. Essential trace elements such as copper, zinc and iron show major changes in neurodegneration, however, we do not understand how this drives disease processes. This proposal will develop an innovative 3D ‘brain on a chip’ cell model to probe the role of trace elements in brain pathology and identify exciting new treatments options.
NHMRC Research Fellowship. Genetic Modification And Differentiation Of Human Pluripotent Stem Cells: Creating Tools For Regenerative Medicine And Models For Disease
Funder
National Health and Medical Research Council
Funding Amount
$757,297.00
Summary
Human embryonic stem cells (hESCs) can form all the cell types in the body. Cells made from hESCs could be used to test new drugs prior to trials in patients and eventually to replace tissues damaged through accident or disease. My laboratory is turning hESCs into blood, heart and insulin producing cells. We can genetically modify such that the cells fluoresce whenever they develop into these cell types. These 'glowing' hESC lines help us to make different cell types more efficiently.
