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.

Regulation Of Megakaryocyte And Platelet Survival In Malignancy

Funding Amount
$536,914.00
Summary
In this grant we will investigate how blood cells called platelets are produced in normal conditions and during disease. Platelets are blood cells that stop us from bleeding when we get a cut. When too many platelets accumulate, there is an increased risk of blood clots forming. This project grant will help us learn how platelet numbers swell in response to some blood and ovarian cancers, and the mechanisms that control cell death in platelets and the cells that produce them.
Too few blood platelets leads to fatal haemorrhage, and patients with low platelet counts require transfusions to prevent bleeding. We have recently discovered the key to keeping platelets alive, and now propose the critical experiments which will teach us how to manipulate it and allow platelets to live longer. Our team leads the world in this field. If successful we expect to improve blood bank platelet storage, and boost the supply of platelets available to patients in need of transfusion.
I am a molecular biologist, with a background in clinical medicine, interested in understanding how, when and why cells die. By clarifying cell death mechanisms, my goal is to exploit this knowledge for better medicines, such as for treating patients with
Bcl-2 Proteins And The Regulation Of The Megakaryocyte Lineage.

Summary
Platelets are tiny cells that circulate in the blood. They are essential for blood clotting. Too few platelets leads to uncontrolled bleeding. Platelets are produced in the bone marrow by cells called 'megakaryocytes'. Cancer chemotherapy often causes dangerous decreases in platelet count - this is thought to be because it kills megakaryocytes. We will pinpoint the molecules responsible for megakaryocyte life and death. This has the potential to make the side effects of chemotherapy less severe.
I am a molecular geneticist dissecting the regulation of hematopoiesis. My lab is primarily concerned with the development and function of the megakaryocytic lineage, from hematopoietic stem cells, through to committed progenitors, megakaryocytes and thei
I am a cardiovascular scientist and interventional cardiologist using biotechnological, molecular and cell biological methods as well as in vivo and ex vivo models to address translational research questions in the fields of inflammation, thrombosis and atherosclerosis. The aim of my research is to better understand the pathogenesis of cardiovascular disease and to develop new diagnostic and therapeutic strategies that ultimately provide direct benefits to patients.
Coronary Atherosclerosis And Its Relationship With Platelet Activation
Funder
National Health and Medical Research Council
Funding Amount
$101,039.00
Summary
Blood clots are critical to the development of heart attacks, which kill many thousands of Australians annually. Platelets are cells in the blood that play an essential role in formation of blood clots, and coronary disease is associated with platelet activation. This research study will investigate the nature of platelet activation in the arteries of the human heart, its relationship to activation of inflammatory cells, and to the severity of narrowings in the arteries of the human heart.
Identification Of A New Thrombosis Mechanism Triggered By Dying Platelets
Funder
National Health and Medical Research Council
Funding Amount
$608,742.00
Summary
A severe reduction in blood flow (ischemia) to the intestines can trigger blood clot formation (thrombosis) in multiple organs, including the lungs. We have identified a new thrombosis mechanism that is triggered by the clumping of white blood cells in the intestines, leading to widespread thrombosis in the lung. Here we will investigate the mechanisms triggering this thrombosis mechanism with the ultimate aim of identifying more effective antithrombotic approaches.
