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.

Enzymes that generate or degrade peptides serve important roles - alterations in their activity can impact on a diverse range of physiological processes in healthy and diseased states. Angiotensin is a peptide that plays a critical role in regulating blood pressure and fluid balance - drugs that block the activity of its processing enzymes forms an important class of medication used to treat hypertension and heart disease. My research interest is in discovering novel roles for these enzymes.
Cracking The Epigenetic Code: Understanding The Mechanisms Of Memory Associated With Anxiety-related Disorders And Their Treatment

Funding Amount
$640,210.00
Summary
The primary goal of my research programme is to elucidate how the epigenome coordinates experience-dependent gene expression underlying associative learning and memory using paradigms relevant for understanding fear-related anxiety disorders. My research on DNA modifications and newly emerging findings in the realm of RNA biology is changing the way we think about gene-environment interactions, the broader impact of which will most certainly continue to be felt for years to come.
Defining The Coordination Of Immune Responses To Pathogens

Funding Amount
$640,210.00
Summary
Understanding how immune responses are coordinated is critical for the design of new therapies and vaccines to target infectious diseases and cancers. This project will utilise advanced imaging combined with novel tools to dissect the complex interactions that occur between immune cells as they are activated and patrol the body to eliminate infectious pathogens.
Defining The Requirements For Effective Immune Responses

Summary
The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host. Individuals with primary immunodeficiencies have defects in the development and/or function of the cells of their immune system and are more susceptible to infectious diseases. This study will investigate such individuals to identify functions for specific genes and immune cells in order to understand the requirements for generating effective immune responses ....The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host.

I am an epidemiologist investigating: 1) the frequency, pathogenesis, risk factors and impacts of common age-related eye disease, particularly focused on the four leading causes of blindness: age-related macular degeneration, cataract, glaucoma and diabetic retinopathy; 2) the potential for screening and clinical diagnostic value of retinal imaging and retinal vascular signs as predictors of major systemic conditions such as hypertension, diabetes and cardiovascular disease.
Transcriptional And Metabolic Regulation Of Effector And Memory Lymphocyte Differentiation

Summary
I am an internationally recognized expert in the field of lymphocyte biology. My work has shed light on antibody production, T cell responses and immune pathology. Specifically, I have identified molecular regulators that link antigen recognition, lymphocyte population expansion, cellular metabolism and effector function. My ongoing work focusses on the development and function of several critically important cell types, including tissue resident lymphocytes and regulatory T cells.
My work focuses on cells of the immune system that act as sentinels on the lookout for invading pathogens and danger. These cells are called dendritic cells. I am particularly interested in understanding how these cells function within the bone marrow environment and how they may sense viral infection or cancerous cells within this tissue. We aim to understand their function in specific diseases including Lupus and in pre-leukemia conditions, and also in infectious and parasitic diseases.
Understanding Universal Immunity To Influenza Viruses

National Health and Medical Research Council
Funding Amount
$687,975.00
Summary
A/Prof Kedzierska’s work combines cutting-edge basic research with unique clinical studies to define how to generate protective immunity against the pandemic and newly emerged influenza viruses. This research will identify key factors that drive the severe and fatal influenza disease in high-risk groups, including the young, elderly, pregnant women and Indigenous Austraians. Findings on the optimal human immunity to influenza viruses will be applicable to other infectious diseases and cancers.
Mapping The Molecular Blueprint For Immune Cell Differentitation

Summary
Killer T cells are white blood cells that are key for helping control virus infections and in the recognition and elimination of cells that have become cancerous. This proposal aims to identify novel molecular mechanisms that control the ability of killer T cells to mediate their antiviral and anti-cancer functions. This will provide molecular targets for possible clinical interventions designed to either promote immunity (vaccination) or limit damage caused by T cell responses that target self
