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.

Superior Surgical Fixation Using A Novel Orthopaedic Expandable Fastener
Funder
National Health and Medical Research Council
Funding Amount
$414,076.00
Summary
Surgeons repair bone fractures using metal plates and screws. Sometimes the screws loosen and the surgery needs to be repeated. Expandable screws are stronger, but more difficult and sometimes impossible to remove. The research team will test a new type of screw that holds the bones together with greater strength (our current work shows 40% stronger) but can be removed easily if necessary. This grant will allow extensive mechanical testing in preparation for a first-in-human clinical trial.
Centre Of Research Excellence In Medicines And Ageing

Funding Amount
$2,601,415.00
Summary
Medicines have an important place in health and are commonly used for long periods, sometimes life-long. Using medicines wisely requires a careful balance between benefits and harmful effects. Currently, there is limited information to guide medicines use over a lifetime. Using large linked datasets, the CRE in Medicines and Ageing will generate much needed evidence about real world medicines use to support clinical and pharmaceutical policy decisions.
My research focuses on the mechanisms responsible for diabetic kidney and heart complications with an emphasis on identifying novel targets as the basis for developing new treatment to reduce the burden of these complications. It is hypothesised that diabetic complications arise as a result of a number of key factors, the most important being chronic elevation of blood glucose.

Summary
Non alcoholic Fatty Liver Disease (NAFLD) threatens to become a major public health problem. Its increasing prevalence is associated with parallel increases in obesity and diabetes. This study aims to understand the mechanisms involved in progression to liver failure and liver cancer in the setting of diabetes and the impact of NAFLD on blood sugar levels and diabetes complications (esp. cardiovascular).

The Role Of Angiotensin Converting Enzyme 2 In Diabetic Complications

National Health and Medical Research Council
Funding Amount
$453,144.00
Summary
Most heart attacks and strokes arise from narrowing of the arteries. This process is regulated by a number of hormonal pathways. One of the most important is the renin angiotensin system. Our group has demonstrated important changes in this pathway which play a pivotal role in regulating the development of atherosclerosis and its response to treatment. It is predicted that these studies will provide critical information to develop innovative treatment strategies for cardiovascular disease.
RAGE And ACE2 Shedding As Therapeutic Targets In Diabetes And Cardiovascular Disease

Funding Amount
$748,447.00
Summary
We have previously demonstrated the pivotal role of two shed proteins, Receptor for Advanced Glycation End-products (RAGE) and Angiotensin Converting Enzyme Receptor 2 (ACE2) in heart disease and diabetic complications. In this project, we will use a novel technologies to modify shedding of these proteins from the cell surface and alter their ability to cause disease.

Summary
After caesarean delivery of a baby most women will require analgesia. Traditionally anti-inflammatory medications (eg.diclofenac) have been given. Evidence exists that this medicine may increase the mother�s blood pressure. This can result in a longer hospital stay, blood pressure medications and exposure to the risks of high blood pressure (eg.stroke and increased bleeding). This study examines the effect of diclofenac on the mother�s blood pressure, analgesia and investigates the mechanisms be ....After caesarean delivery of a baby most women will require analgesia.

50% of the women who died due to swine flu were pregnant. This project will examine if factors produced by the placenta make the pregnant woman more susceptible to influenza.
Characterisation Of Novel AGE Binding Proteins: Implications For Diabetic Vascular Complications.

Funding Amount
$210,990.00
Summary
This project will explore a process known as advanced glycation and in particular how this may lead to organ injury in diabetes. Diabetes is characterised by sustained elevation of blood glucose levels which interact with proteins to generate products known as advanced glycation end-products (AGEs). These AGEs bind to other proteins some of which have been isolated and are considered receptors. Our own group has identified a new family of proteins known as ERM proteins which bind to AGEs.

Diabetes is characterised by sustained elevation of blood glucose levels which interact with proteins to generate products known as advanced glycation end-products (AGEs). These AGEs bind to other proteins some of which have been isolated and are considered receptors. Our own group has identified a new family of proteins known as ERM proteins which bind to AGEs. This is a highly novel finding which now needs to be examined in more detail. The ERM proteins which include ezrin, radixin and moiesin are found at many sites of diabetic complications including the kidney, retina and blood vessel wall. They have a number of functions including effects on cell adhesion and cell structure. This is important in diabetes where changes in cells including altered structure have been observed. This grant will characterise the interactions between AGEs and ERM proteins at the molecular and cellular level. It will define how AGEs influence cells via interactions with ERM proteins. These studies have the potential to lead to treatments that may modulate the AGE-ERM interactions, thereby retarding or preventing diabetic vascular complications. These complications are of important clinical significance since they are the major cause of morbidity and mortality in the diabetic population. Furthermore, diabetes is a major cause of premature atherosclerosis in our community, diabetic kidney disease is the leading cause of end-stage renal failure in the Western world and diabetic retinopathy (eye disease) is the main cause of blindness in the working age population.Read moreRead less
