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.

Integrative Systems Pharmacology, Neutron Reflectometry And Molecular Dynamics Approaches To Unravelling The Interactions Between Polymyxins And Bacterial Membranes
Funder
National Health and Medical Research Council
Funding Amount
$968,005.00
Summary
Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter baumannii are among the 6 top-priority dangerous ‘superbugs’ causing life-threatening infections worldwide. This study will employ a multi-disciplinary approach to decipher the complex interactions of polymyxins with the membranes of these three ‘superbugs’ and to discover novel antibiotics with superior efficacy. This innovative project targets the urgent unmet global medical crisis due to antibiotic resistance.
Defining The Mechanisms Of Action For Ozonide Antimalarials
Funder
National Health and Medical Research Council
Funding Amount
$668,152.00
Summary
Deadly malaria parasites have emerged that are resistant to all classes of approved drugs. Ozonides are a new class of medicines recently approved for malaria, and provide a much-needed treatment option for multi-drug resistant infections. However, the mode of action and potential for cross-resistance is poorly understood. This project will use modern analytical techniques to measure the impact of ozonides on parasite biochemistry to reveal mechanisms involved in drug action and resistance.
UGT Enzymes In Chemotherapeutic Drug Metabolism: New Avenues To Improve Drug Response And Overcome Resistance
Funder
National Health and Medical Research Council
Funding Amount
$610,005.00
Summary
Tumours treated by chemotherapy often become resistant to the drugs, leading to relapse and reduced chance of survival. We will study one of the main pathways leading to drug resistance, which could lead to the development of new ways to overcome resistance and improve cancer treatment outcomes.
Combating Bacterial 'superbugs' By Innovative Antibiotic Combination Strategies
Funder
National Health and Medical Research Council
Funding Amount
$421,747.00
Summary
Resistant bacteria are among the 3 most serious threats to human health. This project will substantially improve our quantitative understanding of how bacteria survive antibiotics and enable the design of innovative antibiotic combination therapies to combat resistant ‘superbugs’. My research outcomes will inform clinicians how to optimally use available antibiotics and greatly support rational development and optimisation of new antibiotics in collaboration with pharmaceutical industry.
Glucocorticoid Resistance: Identifying New Anti-inflammatory Drug Targets
Funder
National Health and Medical Research Council
Funding Amount
$453,287.00
Summary
The control of chronic inflammatory diseases such as asthma involve use of drugs related to the steroid hormone cortisol. Up to 40% of patients with more severe disease respond poorly or not at all to these drugs. The remaining non-steroid treatments are only partially effective. Poor disease control is a great health and economic burden. We have identified a molecular mechanism for steroid resistance and propose new studies to identify novel drugs that act to reverse steroid resistance.
