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.

Discovering How A Novel Anti-malarial Drug Series Rapidly Kills Parasites
Funder
National Health and Medical Research Council
Funding Amount
$672,971.00
Summary
We have developed a new set of highly potent anti-malarial drugs but we do not know how they work. Identifying how these compounds work is important for improving their effectiveness and safety. We will discover how these drugs kill parasites by using a number of cutting edge methods that could also be useful for discovering how other drugs work. Data generated will progress these compounds along the drug development pipeline which urgently needs a constant supply of new antimalarials.
THE IMMUNOLOGICAL LEGACY OF OBESITY ON VIRAL PATHOGENESIS
Funder
National Health and Medical Research Council
Funding Amount
$652,275.00
Summary
Obesity is a key risk factor for severe viral infections. Our preliminary data suggest that in mice this susceptibility is not reduced by weight loss. In this grant we will investigate a) the mechanisms driving the legacy effect of obesity on antiviral immunity b) whether or not we can reverse this legacy effect by treatment with the drug MCC950 and c) the antiviral response of overweight children and adults who have and haven't recently lost weight.
Oleoyl-ACP-hydrolase As An Early Predictive Biomarker For Severe And Fatal Influenza
Funder
National Health and Medical Research Council
Funding Amount
$866,807.00
Summary
Millions are hospitalized with severe influenza disease and ~500K die annually but the underlying mechanisms that drive disease are still not fully understood. We have identified a key role for an enzyme involved in fatty acid metabolism, which is profoundly elevated in patients who succumb to influenza and is thus a predictor for fatal outcomes. This research aims to investigate how this enzyme affects infection and impairs immune responses to drive severe respiratory viral disease.
Harnessing The Dual Roles Of Pericytes To Improve Stroke Outcomes
Funder
National Health and Medical Research Council
Funding Amount
$853,943.00
Summary
Pericytes are cells that are in the walls of capillaries - the smallest blood vessels. Pericytes control blood flow and help promote recovery after injury. In stroke, pericytes squeeze the capillary shut, limiting the amount of energy getting to the brain. This proposal will use innovative techniques to understand how pericytes limit blood flow and also how we can utilise pericytes to improve brain recovery after stroke. This will allow us to identify new potential treatment options for stroke.
Tuberculosis kills more people than any other infectious disease, and approximately one-third of the world's population is latently infected with Mycobacterium tuberculosis. This situation is largely due to the low efficacy of the only licensed TB vaccine, BCG, and the 'black box' of what constitutes protection against TB. This project aims to unravel the mechanisms of protective immunity against TB to develop a highly protective vaccine.
Developing New Immunotherapeutics Through Studying Immune Effectors In Situ
Funder
National Health and Medical Research Council
Funding Amount
$1,369,054.00
Summary
The immune system deploys pore forming proteins to clear viral and bacterial infections and to eliminate cancerous cells. The unwanted activities of these molecules, however, results in chronic disease and in transplant rejection. We aim to understand how pore forming immune weapons interact with our own cells, with the goal of using this information to develop new approaches to treat immune driven disease and to improve the success of transplantation therapy.
Therapeutic Targeting Of Interleukin-22 For Severe Paediatric Urinary Tract Infection And Associated Renal Complications
Funder
National Health and Medical Research Council
Funding Amount
$997,139.00
Summary
Urinary tract infections are among the most common bacterial infections and are associated with the development of chronic kidney disease. The bacteria that cause these infections are becoming increasingly resistant to antibiotic therapy. Therefore, new strategies that target the immune system rather than the bacteria are urgently needed. This study will provide evidence for re-purposing novel immunotherapies targeting the protein interleukin-22 that are being developed for other diseases.
Harnessing Tyrosine Metabolism To Combat Respiratory Diseases
Funder
National Health and Medical Research Council
Funding Amount
$866,467.00
Summary
Cross-talk between our immune system and the microbiome is central to health and disease. In particular, the gut microbiome has wide-ranging effects throughout the body, in part through the production of metabolites with immunomodulatory activity. We have discovered a novel subset of microbial metabolites which can protect mice against allergic airway inflammation, a model of asthma. We now aim to discovery how these metabolites work with a view towards developing them as therapeutics.
Flaviviruses Must Come Of Age: Design Of Stable, Mature Particles By Structural Vaccinology
Funder
National Health and Medical Research Council
Funding Amount
$1,149,487.00
Summary
We have established a powerful toolset combining advanced structural biology and rapid virus engineering that allows us investigate the assembly of flaviviruses in novel ways. This project will integrate these approaches to investigate the role of new ligands that we have identified in the structure of medically-relevant flaviviruses including dengue virus and delineate a novel maturation path for flaviviruses, which will be used to design safer and more effective flavivirus vaccines.
Targeting MiRNA Biogenesis To Treat Herpes Simplex Virus Latency
Funder
National Health and Medical Research Council
Funding Amount
$800,085.00
Summary
Herpes simplex virus (HSV) causes cold sores in most infected people, but can also cause blindness and fatal brain infections. The biggest problem with HSV is that it never completely goes away - the virus hides in a part of the nervous system and can come out to cause disease over and over again. We have recently discovered a gene in people that the virus needs to maintain itself in this hidden state. In this project we will use this exciting discovery to work towards a cure for HSV.
