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.

Targeting Hypermutable ‘superbugs’ In Chronic Respiratory Infections By Optimised Antibiotic Combination Dosage Regimens
Funder

Funding Amount
$697,731.00
Summary
Many bacterial ‘superbugs’ can increase their mutation rate, i.e. become hypermutable, and thus rapidly become resistant to multiple antibiotics. Chronic lung infections with hypermutable bacteria cause increased ill-health and death in patients and current treatments do not work well. We will develop improved treatments using combinations of available antibiotics. This project will provide guidance to doctors on how to treat infections more effectively and minimise emergence of resistance.
Targeting Bacterial ÏsuperbugsÍ By Innovative Combination Dosing Strategies And New Antibiotics
Funder
National Health and Medical Research Council
Funding Amount
$463,650.00
Summary
This research project will elucidate the mechanistic basis to optimally combine available beta-lactam antibiotics to prevent resistance of gram-negative bacterial ïsuperbugsÍ. These mechanistic insights will be utilised to develop novel antibiotics that are active against these multidrug-resistant bacteria. The interdisciplinary project will substantially contribute to solving the global crisis due to multidrug-resistant bacteria and inform the design of effective new antibiotics.
Combating Bacterial ‘superbugs‘ By Innovative Dosing Strategies That Combine Available Antibiotics To Prevent Resistance
Funder

Funding Amount
$547,694.00
Summary
As resistant bacterial ‘superbugs’ are among the 3 most serious threats to global health and as new antibiotics are lacking, innovative strategies to prevent bacterial resistance are urgently needed. This proposal will yield molecular insights on optimal combinations of current beta-lactam antibiotics to maximise bacterial killing without resistance. This project will provide guidance to physicians on how to optimally combine available beta-lactam antibiotics to prevent bacterial resistance.
Microparticles And Selective Trait Dominance In Multidrug Resistant Cancers

Summary
Multidrug resistance (MDR) is the cause of treatment failure in 90% of patients with metastatic cancer. We recently discovered a novel resistance mechanism in which microparticles provide a vehicle for intercellular transfer of MDR. We now report that MP play an even more significant role in conferring MDR, by the ñre-templatingî of cancer cell traits. This has considerable potential for translation into clinical outcomes with the identification of alternative drug targets and therapeutics for t ....Multidrug resistance (MDR) is the cause of treatment failure in 90% of patients with metastatic cancer.

Drug Targeting To Sites Of Lymph-adipose Interaction To Transform The Treatment Of Disease
Funder
National Health and Medical Research Council
Funding Amount
$515,172.00
Summary
Insulin resistance (IR) underpins the development of inadequately treated heart and metabolic diseases such as type 2 diabetes. Recently we demonstrated that high fat diets promote increased leakage of fluid from lymph vessels to abdominal fat, and that increased access of lymph fluid to fat stimulates fat expansion and changes in fat function that promote IR. This project seeks to optimise novel drug delivery strategies that target lymph and fat and more effectively treat IR.
Targeting Polymyxin-resistant Gram-negative Superbugs: Development Of Novel Antimicrobial Lipopeptides
Funder
National Health and Medical Research Council
Funding Amount
$661,069.00
Summary
Prevalence of resistance to antibiotics among Gram-negative 'superbugs' is a major global medical challenge, which is highlighted by the Bad Bugs, No Drugs campaign of the Infectious Diseases Society of America. There are virtually no new antibiotics in the current drug development pipeline for these dangerous pathogens. In this project, novel lipopeptides will be designed, synthesised and evaluated against these 'superbugs'. Information obtained will be crucial for further drug development.
