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.

In Vivo Imaging Of Protective And Malignant B Cell Function
Funder
National Health and Medical Research Council
Funding Amount
$431,412.00
Summary
B cells are responsible for producing antibody that protects us from infection. Disruption of healthy B cell function can lead to a myriad of diseases including immunodeficiency, autoimmunity and blood cancers such as leukaemia. The aim of my work is to use powerful microscopy to visualise how mutated B cells interact with their surrounding environment in real-time. These studies will allow the development of new treatments for cancer and immune conditions that target these interactions.
Investigating B Cell Development, Maintenance And High-affinity Antibody Production By ENU Mutagenesis
Funder

Funding Amount
$408,388.00
Summary
B cells are essential for the protection against infections. This application aims to identify new genes that are crucial for the development or function of B cells and will investigate how mutations in newly discovered genes contribute to defects in the development and function of B cells and the pathogenesis of B cell leukaemia.
Manipulation Of Haematopoietic Stem Cell Niches To Improve Therapeutic Outcomes

Funding Amount
$451,716.00
Summary
My aim is to understand how stem cells are naturally regulated by the body. My central hypothesis is that local environment (niche) factors largely govern stem cell behaviour. Identification and manipulation of these factors will offer a novel therapeutic opportunity to improve the clinical use of normal haematopoietic stem cells to improve transplantation success, as well as sensitise leukaemia cells to chemotherapy.
Improving Patient Outcomes In Leukaemia By Targeting Cancer Stem Cells
Funder

Funding Amount
$294,763.00
Summary
Blood cancers such as acute myeloid leukaemia (AML) are among the most deadly types of cancer and new treatments are desperately needed to improve patient’s survival in these diseases. AML cancer-causing stem cells survive by turning on immortalization programs and we hope to specifically kill these AML stem cells by blocking these crucial pathways. This includes things that control the way the cells divide and the way they respond to genetic damage as well as other novel pathways.
In Vivo And Biochemical Appraisal Of Mitochondrial STAT3
Funder

Funding Amount
$421,747.00
Summary
The Signal Transducer and activator of transcription 3 (STAT3) protein is over-expressed or activated in most cancers. The paradigm for STAT3's role in cancer is that it drives the expression of genes which support tumour growth. Recently I found that STAT3 controls the altered metabolic state required for cancer progression, both by control gene expression and by entering the mitochondria. I propose define the mechanism of STAT3 mitochondrial activity and then translate these findings into anim ....The Signal Transducer and activator of transcription 3 (STAT3) protein is over-expressed or activated in most cancers.

New Therapies For Stroke – Preventing Stroke Progression And Enhancing Recovery
Funder
National Health and Medical Research Council
Funding Amount
$463,652.00
Summary
Stroke is a major cause of death and disability worldwide. Dr Spratt’s team have discovered a new mechanism causing pressure to rise in the skull after stroke. They will build on their discovery of a promising new therapy to prevent early worsening of stroke and improve patient outcomes. He also leads a team studying better stroke recovery by promoting activity by enriching the rehabilitation environment, and ways to improve fitness in stroke survivors.
Identification Of Novel Targeted Therapies For JAK2-driven Leukemogenesis
Funder
National Health and Medical Research Council
Funding Amount
$392,717.00
Summary
Many leukemias are caused by particular signalling molecules becoming too active in blood cells. My research focusses on the molecules that are required by leukemic cells for their growth and survival. I will use mice that are prone to developing leukemia to study how these leukemias can be treated with drugs that block specific molecules. My goal is to discover new ways to treat leukemias that work better and have fewer side effects than current treatments.
Transcriptional Regulation Of Hematopoietic Commitment
Funder
National Health and Medical Research Council
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 proposed program of work aims to shed light on dietary, environmental and genetic factors that may be related to the risk of childhood cancers. Identifying these risk factors, and how they interact with each other, will provide clues as to how childhood cancers may be prevented. The research program includes a number of Australian and international studies, which will involve collaboration between doctors and research scientists from a range of disciplines.
Investigation Of Haematopoietic And Leukemia Stem Cell Self-renewal.
Funder
National Health and Medical Research Council
Funding Amount
$415,218.00
Summary
The blood stem cell properties of self-renewal and multipotency allows for the constant replenishment of all blood components. Blood cancer stem cells use self-renewal to propagate disease, and can enter a quiescent-dormant phase to evade treatment. My research focuses on the identification and mechanisms of new genes that govern these unique blood stem cell properties, and to investigate whether these genes are also important in blood cancers.
