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.

Transcriptional Regulation Of Hematopoietic Commitment
Funder

Funding Amount
$289,985.00
Summary
Blood cell formation is a tightly regulated process and provides an important model for our understanding of blood homeostasis. Perturbations result in a number of disorders such as leukaemia. The application of stem cells to many diseases is being pursued; yet, to be successful knowledge of normal cellular behavior is crucial. I aim to improve our understanding of these processes and help to provide the framework for future studies aimed at more directly manipulating blood cell functions.
The Role Of Cell Cycle Control In Haemopoietic Stem Cell Fate Decisions.

Funding Amount
$390,974.00
Summary
My research has focused on understanding how the process of cell division can result in different outcomes for adult blood stem cells. I am interested in determining the role of bone and blood vessels in the regulation of blood stem cells and in the development of blood diseases (myeloprolifertive disease). I will also determine the effects of changing the cell cycle with drugs to improve transplantation of blood stem cells.
The emerging interdisciplinary field, mechanobiology, is focused on understanding how cells sense their surroundings and transfer biomechanical signals to initiate cellular changes. I aim to develop hydrogel platforms with differential stiffness patterns to study cellular mechanotransduction and to generate heart muscle cells. The findings have the potential to greatly improve the clinical outcomes where more than 10 clinical trials failed to show successful regeneration after heart attack.
Mechanisms Underlying The Effects Of Retinoic Acid Receptor Gamma In Haemopoiesis And Bone Homeostasis

Funding Amount

Summary
My recent studies have demonstrated that a model of vitamin A deficiency results in impaired blood cell production and contributes to a blood cell disorder that can progress to leukaemia. There are also reduced numbers of blood stem cells (which give rise to all blood cells) and bone (which helps to regulate blood cell production) in this mouse model. In these studies I seek to understand more on how vitamin A deficiency causes these defects, which may lead to better treatment of such diseases.
Stem And Progenitor Cell Contribution To Skin Wounds And Homeostasis

Funding Amount
$408,388.00
Summary
Skin wounds represent a major health and economic burden. Although skin stem cells have been used routinely for the treatment of wounds, they cannot reconstitute a fully functional skin given the complexity and the many cell types usually involved in wound healing. In this project, we intend to evaluate the role of different cell populations on modulating skin wound healing to produce more regeneration and less scaring.
Using Connective Tissue Stem Cells To Treat Human Disease.

Funding Amount
$419,180.00
Summary
In our recent Cell paper (January 15, 2015), we reported our discovery of two new adult stem cells. One of these, the osteochondroreticular (OCR) bone stem cell (pronounced “ocker” stem cell) has a particular affinity for developing cartilage. We are testing if this cell could be used as a new treatment for osteoarthritis. The second new stem cell we discovered, is called the iRSC, and lies within the intestine. We are studying this cell in the development and treatment of bowel cancer.
Adding New Cells To The Mature Central Nervous System - Their Role In Plasticity, Maintenance And Repair.

Funding Amount
$459,270.00
Summary
There are a number of immature cell populations in the central nervous system. This project aims to understand the biology of each stem cell population and the signals that direct them to generate new brain cells. We aim to utilize these cell populations for nervous system repair.
Cell Therapy For Functional Reconstruction Of Damaged Brain Circuitry
Funder

Funding Amount
$401,361.00
Summary
Unlike many organs in the body, the brain has an extremely limited capacity to repair itself when damaged. A promising approach for repairing the damaged brain, as may occur through neurodegenerative disease or traumatic brain injury, is to replace the cells lost to the injury by transplanting new ones directly into the brain of the patient. This research proposal involves the use of stem cells to repair damage to the brain caused by Parkinson's disease, stroke or traumatic brain injury.
