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.

The Effect Of Defective Iron Handling On Immune Function And Pseudomonas Aeruginosa Infection In The Cystic Fibrosis Lung

Funding Amount
$97,213.00
Summary
In this research higher degree I will study the effects of iron on airway sepsis in cystic fibrosis (CF), with a particular focus on the major pathogen Pseudomonas aeruginosa. Increased concentrations of iron have been described in the CF lung, and CF airway epithelial cells display abnormal iron handling which facilitates P. aeruginosa growth. I will explore imposed iron limitation combined with conventional antibiotics as a new therapeutic strategy for treatment of chronic airway infection.
Bacteriology Of Bronchiectasis In Australian Indigenous Children
Funder
National Health and Medical Research Council
Funding Amount
$91,209.00
Summary
Many Indigenous children in the Northern Territory suffer from a chronic lung condition called bronchiectasis. This disease causes a lot of illness and can lead to early death in adulthood. Little is known about how the disease starts and how it can be prevented, but many children are being treated with the antibiotic azithromycin. My project aims to find out which bacteria are associated with bronchiectasis, how azithromycin affects the bacteria, and whether it leads to antibiotic resistance.
Vitamin D And Acute Lower Respiratory Tract Infection (ALRI) In Indigenous Children
Funder
National Health and Medical Research Council
Funding Amount
$92,669.00
Summary
Australian Indigenous children experience extreme rates of acute lower respiratory infection (ALRI) that medical interventions have failed to reduce. Vitamin D is an important immunoregulatory molecule of the respiratory system that remains uncharacterised in this population. We propose that deficiency contributes to the persistent rates of ALRI. This study will characterise vitamin D levels in a cohort of Indigenous children with and without ALRI. The results will guide future intervention.
