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.

Many bacterial pathogens invade host cells to replicate and avoid detection by the host. These pathogens interact with the host and by manipulating it to its benefit they establish an environment to survive in. A detailed understanding of the targeted hosts pathways and which are essential for pathogen survival is knowledge that will allow future development of therapeutic intervention strategies.
Dissecting The Role Of NOD-like Receptors (NLRs) In Helicobacter Pylori Disease

Summary
Half of the world's 6.5 billion people harbour the bacterium Helicobacter pylori in their stomachs. Approximately 1% of these infections develop into gastric cancer, representing the second leading cause of cancer-related death world-wide. This research project will investigate the role of a family of host defence proteins as mediators of inflammatory and cell survival responses which contribute to the development of gastric cancer disease.
Understanding the basic biology of cells will allow us to pinpoint key mechanisms and molecules that underpin multiple diseases and are targets for treatments. The broad aims of this research program include the development of new therapies for chronic inflammatory diseases, understanding how proteins are sorted and trafficked inside cells in processes that are essential to immunity and cancer biology, and identifying new intracellular targets to block bacterial invasion and infectious diseases.
Pattern Recognition Receptors In Inflammation And Infection

Summary
Innate immunity provides our first line of defence against infections, but pathogens can overcome this system. Understanding how microbes disable innate immunity can teach us how to prevent and/or treat infectious diseases. Innate immunity acts by initiating inflammation. Many important acute and chronic diseases develop when this process is dysregulated. Blocking innate immunity thus has potential to treat many diseases. This project aims to understand innate immunity in these contexts.
The transplantation of healthy stem cells from a donor into a recipient with blood cancer (stem cell transplantation) is the most effective curative therapy for the majority of patients. Unfortunately this process results in unwanted, often fatal, side effects including infection, a rejection process known as graft-versus-host disease and in some patients, the leukaemia still recurs. This research will refine new treatments focused on overcoming these limitations and improving transplant outcome
Molecular Mediators, Epigenetic Modulators And Therapeutic Targets For Cognitive Disorders

Summary
Brain disorders constitute an enormous, and growing, burden. My research investigates how genes and environment combine to cause disorders of cognition, including dementia, schizophrenia and autism. The research will provide new insights into these disorders, at the level of molecules, cells and behaviour. I will explore how genetic and environmental factors interact, with a focus on mental activity, physical exercise and stress, which affect a range of neurological and psychiatric disorders.
I am a hematologist with expertise in the science of immunology and clinical experience in bone marrow transplantation and the treatment of hematological malignancies. My vision is to study the biology of dendritic cells, which are the specialized white cells that initiate the immune response, and then, to apply this knowledge to the design and introduction of novel diagnostic and therapeutic immune strategies, to improve the survival of patients with leukemia, lymphoma and multiple myeloma.

Summary
This Senior Principal Research Fellowship will develop and evaluate system-wide interventions to improve psychosocial outcomes of Australians diagnosed with cancer, including Chinese-speaking immigrants; identify long-term challenges for cancer survivors; explore the impact of having multiple gene testing; and evaluate interventions to empower patients to make informed choices regarding cancer treatment.
Gene-environment Interactions, Experience-dependent Plasticity And Pathogenic Mechanisms In Mouse Models Of Cognitive And Affective Disorders. Mental And Physical Activity As Modulators Of Brain And Behaviour In Healthy And Diseased States.

Funding Amount

Summary
Our aim is to understand how genes and environment combine to affect susceptibility to various brain disorders. We are using specific models involving human gene mutations associated with diseases, and manipulating environmental factors such as mental and physical activity. We are focused on neurological and psychiatric disorders, including Huntington’s disease, depression and schizophrenia. These efforts to understand brain diseases will facilitate development of therapeutic approaches.
