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.

Identifying The Molecular Basis Of Memory B Cell Function And Human Immunoglobulin E Memory Via Hyper Immunoglobulin E Syndromes
Funder
National Health and Medical Research Council
Funding Amount
$96,009.00
Summary
Memory B cells generate rapid and potent antibody responses to known threats. The molecular basis for this is unknown, but defects increase the risk of infection, autoimmunity, and allergy. Autoimmunity and allergy are often mediated by a poorly understood antibody subclass, immunoglobulin E (IgE). My project will use emerging single-cell technologies to reveal the molecular mechanisms of antibody memory and IgE regulation, enabling the design of superior vaccines and immunomodulatory therapy.
Development Of Clinical Algorithms To Diagnose And Predict Prognosis Of Food Allergy
Funder
National Health and Medical Research Council
Funding Amount
$136,636.00
Summary
Australia has the highest rate of food allergy internationally. Despite ongoing research into the area, there is currently no cure, with patient avoidance the most effective mode for the prevention of food allergy. A food challenge still the gold standard for food allergy diagnosis, and although definitive, is associated with a risk of anaphylaxis. My research aims to identify the biological differences between active disease and being healthy to develop novel diagnostic methods for food allergy
Novel Methods To Diagnose Clinical Egg Allergy And Predict Prognostic Outcomes

Funding Amount

Summary
Australia has the highest rate of food allergy in the world. Despite ongoing research into the area, there is currently no cure, with patient avoidance the most effective way to prevent food reactions. A food challenge is the gold standard for food allergy diagnosis. Although definitive, it is associated with a risk of anaphylaxis. My research aims to identify the biological differences between having food allergy and not having food allergy to develop novel diagnostic methods.
The Regulation Of IgE Antibody Production By Antigen-specific B Cells
Funder
National Health and Medical Research Council
Funding Amount
$454,105.00
Summary
Asthma and other allergies are caused by the inappropriate production of IgE antibodies by the immune system. IgE is not produced in response to most infections but the controls that normally prevent IgE production are unknown. We have identified two separate molecules that prevent IgE production during immune responses. In this proposal we aim to investigate how these controls work. This information may help to devise strategies for controlling IgE production and therefore allergic disease.
Winter-only Treatment With Omalizumab To Prevent Asthma Exacerbations In Children.
Funder
National Health and Medical Research Council
Funding Amount
$738,855.00
Summary
Acute exacerbations of asthma add considerably to the economic and social burden imposed by asthma. Current asthma treatment frequently controls underlying asthma but does not prevent acute exacerbations in exacerbation-prone asthmatics. This trial, based on our asthma research, provides new hope that acute asthma can be prevented.
Modeling Human Actin Related Protein 2/3 Complex Subunit 1B (ARPC1B) Deficiency In Mice
Funder
National Health and Medical Research Council
Funding Amount
$755,005.00
Summary
The actin cytoskeleton forms the structure that not only keeps cells in their normal shape but is also essential for the movement of cells and for interaction between cells. We have recently identified the first patients with an immunodeficiency caused by a defect in a gene called ARPC1B, which plays a crucial role in the regulation of actin. Through the investigation of novel mouse models we will elucidate the pathomechanism underlying the disease of these patients.
Investigation Of Cellular Abnormalities And Synapse Formation In DOCK8 Immunodeficiency
Funder

Funding Amount
$318,284.00
Summary
Why do some people get allergies? Or serious infections? To investigate this we will study mice and humans with a mutation in the DOCK8 gene. People with mutations in the DOCK8 gene get Hyper-IgE Syndrome and develop severe viral infections of the skin as well as allergic disease. By investigating how DOCK8 works in the cells of the immune system, we hope to understand why these infections and allergies occur and find out why these problems can also happen in those without this specific genetic ....Why do some people get allergies?
