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.

Tissue Specific Antigen Presenting Cell Functions During Infection.
Funder
National Health and Medical Research Council
Funding Amount
$555,325.00
Summary
T cell activation is often inefficient following infection or vaccination, resulting in poor control of pathogens. In this grant, we propose to investigate the cellular basis for sub-optimal CD4+ T cell activation following infection. Specifically, we will study the roles of antigen presenting cells in CD4+ T cell activation in an experimental model of visceral leishmaniasis caused by the human protozoan parasite Leishmania donovani.
Immunoregulation, Innate And Adaptive Immunity, Viral Immunology, Ocular Immunology, Immunotherapy
Funder
National Health and Medical Research Council
Funding Amount
$880,454.00
Summary
The focus on our research is to understand how the immune system responds to viral challenges and how viruses attempt to counteract immune responses. We focus on systemic disease, as well as disease that involve the eye. Understanding how immune responses are regulated will allows us to develop improved therapies
Convergence of biomaterials and immunology: a technology platform for delayed burst release of vaccines. A large challenge in vaccination, particularly in wildlife such as for the growing problem of Chlamydia in koalas, is to provide the necessary booster shots. This project will develop implants that will be inserted under the skin at the time of the first shot, and will spontaneously burst later to release the booster shot to provide protection.
Visualising chromatin changes in 3 dimensions: super to ultra resolution. Packaging of genomic information into the nucleus of a cell necessitates the formation of tightly compacted and highly organized genomic structures within the nucleus, a configuration that is inherently repressive for gene transcription. Hence, mechanisms that alter the spatial organisation of DNA are critical to enable a variety of genome functions, including DNA transcription. This proposal will utilise novel adaptations ....Visualising chromatin changes in 3 dimensions: super to ultra resolution. Packaging of genomic information into the nucleus of a cell necessitates the formation of tightly compacted and highly organized genomic structures within the nucleus, a configuration that is inherently repressive for gene transcription. Hence, mechanisms that alter the spatial organisation of DNA are critical to enable a variety of genome functions, including DNA transcription. This proposal will utilise novel adaptations of super resolution microscopy to visualise in 3 dimensions how changes in chromatin modifications impact genome spatial organisation within the nucleus, and how this then links to cellular differentiation. This will provide a picture of how spatial organisation within the nucleus supports general cell differentiation.

The Impact Of Obesity On Immunological Tolerance Of The Fetus
Funder
National Health and Medical Research Council
Funding Amount
$378,366.00
Summary
Obesity increases the risk of miscarriage during pregnancy. The reasons for this are not known, although it is thought that abnormal levels of hormones and metabolic parameters are a contributing factor. We hypothesise that the immune system plays a role. In this project we will determine if obesity upsets the fine-tuning of the immune system that is crucial for successful pregnancy. Understanding the reason behind adverse pregnancy outcome will allow appropriate management of maternal obesity.
I am an immunologist determining how the immune system is regulated, with the aim of preventing diseases such as asthma, type 1 diabetes and multiple sclerosis caused by dysregulated immune responses.
The lymphocyte plays a vital role in our immune defence. When lymphocytes encounter a foreign invader, such as a virus, they make a series of decisions that influence the strength, type, and longevity of the immunity created. This program aims to understand how lymphocytes make decisions at the molecular level that affect cell and whole of system level behaviour. We aim to improve vaccines and understand diseases such as allergy, lupus, arthritis and leukaemia to develop novel therapies.
Dengue Fever Vaccine: Towards Low Cost Production And Delivery
Funder
National Health and Medical Research Council
Funding Amount
$612,039.00
Summary
With rising populations and a warming climate mosquito borne viral diseases will become more prevalent and low-cost vaccine production & delivery systems will become increasingly important. Here a microalgae based vaccine production platform will be coupled to proven Nanopatch & low cost oral vaccine delivery. The focus is on a Dengue virus vaccine, as Dengue causes 400 million infections & 100 million symptomatic cases annually.
Colorectal cancer is a leading cause of cancer-related deaths worldwide. Chronic inflammation is recognized as a predisposing factor for the development of colon cancer, but the molecular mechanisms linking inflammation and tumourigenesis have remained elusive. Our work will dissect the cellular and molecular circuitry that leads to tumourigenesis and investigate interventions aimed to significantly slow or prevent tumour formation. This work will have significant implications for treatments of ....Colorectal cancer is a leading cause of cancer-related deaths worldwide.
