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.

HTLV-1 is a lifelong infection of immune cells that sustains high infection rates up to 45% in key Australian communities. Despite HTLV-1 causing serious malignancy and inflammatory co-morbidities that shorten lifespan, few biomedical interventions are available. We will examine how the virus grows and alters immune responses to cause disease. With this, we can develop antiviral treatments to reduce virus infected cells, and make new diagnostic biomarker assays suitable for remote settings.
From Bench To Bedside: A New Treatment For Chronic Rhinosinusitis

Funding Amount
$2,360,520.00
Summary
My research focuses on diseases of the upper airways, in particular chronic relapsing infections and inflammation of the nose and sinus mucosa and on improving wound healing after surgery. My research is translational, aimed at defining new treatments for these diseases. I have invented novel products that improve wound healing after surgery and instruments that help surgeons perform their surgeries in a better and safer way.
Optimising The Therapeutic Efficacy Of Anti-inflammatory Macrophages For Use In Chronic Kidney Diseases

Summary
Chronic kidney disease (CKD) is a major cause of death and morbidity in Australia. Current treatments that are able to delay progression for CKD are limited. As a consequence, more than 2300 additional Australians need kidney replacement each year and many more die of kidney failure. We have reduced and prevented injury in a mouse model of CKD by administering protective white blood cells - macrophages. This project will modify macrophages ex vivo to optimize them for use as a therapy for CKD.
Understanding The Role Of Infectious Agents As A Trigger Of Crohns Disease In Children With Early Onset Disease

Summary
Crohn's disease is a major cause of illness throughout the world. There is no cure and current therapies carry substantial risks. An infectious agent has been suggested as the trigger for disease but research has been inconclusive. Our study focuses on the characterisation of a novel virus we have identified that may trigger Crohn's disease in children at disease onset.
Characterisation Of The Anti-inflammatory Properties Of The N-3 Fatty Acid Product, 4-hydroxy-hexenal.

Summary
A concerted effort is being made by experts in the field of omega 3 fats (fish oils) to make specific recommendation on their use to improve human health . We have reasoned that the characterisation of a major oxidation product of these oils could be a key to understanding how these fats benefit us. The project is likely to influence the formulation of fish oils to enhance their health promoting properties.
A type of white blood cell, the macrophage, is a key player in determining the chronicity of inflammatory conditions such as rheumatoid arthritis, atherosclerosis, psoriasis, nephritis, multiple sclerosis etc. Two particular proteins can control macrophage development and functions, both under normal conditions and during inflammation. The project aims to understand this control. More rational ways to suppress inflammation due to aberrant macrophage function should result.
Development Of Potent And Selective Blockers Of Acid Sensing Ion Channels For The Treatment Of Pain

Funding Amount
$578,704.00
Summary
More than three million Australians suffer from chronic pain, and there are few effective drugs available for treating this condition. A 2007 Access Economics Report estimated the economic burden of chronic pain in Australia at $34.3 billion. Acid-sensing ion channels (ASICs) are a recently discovered family of proteins that play a key role in sensing pain. The goal of this project is to develop potent blockers of these channels that can be used to treat patients suffering from persistent pain.
Exploring The Mechanisms Of Generation Of Intestinal TH17 Responses And The Mechanisms Of TH17 Mediated Pathology

Funding Amount
$617,531.00
Summary
Our research recently described a mouse that shows excellent similarities to human inflammatory bowel diseases. We further show that the disease mediating substances called cytokines are also similar between our mouse and UC. Particularly, a recently described network of cytokines that are the major mediators of disease in our mice and human IBD. This project examines how we can best interfere with the actions of these cytokines to treat and prevent intestinal inflammation.
Elucidating The Role Of Mast Cell Tryptases In Chronic Obstructive Pulmonary Disease And Crohn's Disease

Summary
Smoking leads to inflammation that causes emphysema and inflammation in the lung and gut, which are major health problems. Once induced, there is a progressive decline in health and there are no effective treatments. Particular proteins and small genes have been discovered that control inflammation in these diseases. We may be able to control these proteins/genes and stop the progression of emphysema and gut inflammation. This project may lead to a completely new way of preventing and treating t ....Smoking leads to inflammation that causes emphysema and inflammation in the lung and gut, which are major health problems.

Local SAA Production Drives Glucocortosteriod Resistant Airway Inflammation In COPD

Funding Amount

Summary
We have recently identified a blood marker termed SAA that is highly elevated during an acute attack of Chronic Obstructive Pulmonary Disease (COPD) mainly caused by chest infections. These episodes are a major cause of hospitalisation. Our previous studies suggest that by measuring blood SAA levels we can prevent a worsening of the attack with early intervention. We are now exploring the biological role of SAA and whether blocking SAA activity will benefit COPD patients.
