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.

Dementia is the third leading cause of death in Australia and the single greatest cause of disability in the elderly. Current therapies for Alzheimer’s disease (AD), the most common form of dementia, are inadequate and fundamentally new treatment approaches are required. The aim of this proposal is to develop novel drug candidates for the treatment and prevention of AD and other neurodegenerative disorders by targeting a class of cell-surface receptors called G protein-coupled receptors (GPCRs).
Development Of Blood-based Biomarkers For The Early Detection Of Brain Amyloid And The Investigation Of The Natural History Of Alzheimer’s Disease.

Summary
To have a direct impact on the diagnosis and treatment of Alzheimer’s and other neurodegenerative diseases we need a detailed molecular understanding of the proteins that drive the disease. My laboratory develops and applies the most advanced analytical tools available to develop blood-based markers that can detect the development of Alzheimer’s disease before symptoms occur. This Fellowship will allow me to expand our understanding of the natural history of Alzheimer’s disease.
Establishing A Blood-based Biomarker Panel For Pre-clinical Alzheimer’s Disease

Summary
The current gold standard biomarkers for Alzheimer’s disease (AD) are uneconomical and invasive, thus impeding early treatment prior to irreversible damage. I posit that biochemical changes associated with the disease are reflected in the blood several years prior to the clinical manifestation of the disease. Therefore, I propose to investigate these changes in individuals predisposed to AD, prior to the appearance of clinical symptoms, to identify biomarkers for the early diagnosis of AD.
Role Of Apolipoprotein D In Alzheimer's Disease And Frontotemporal Dementia

Summary
ApoD is a highly conserved lipocalin known for its antioxidant nature and role in regulation of inflammation. Oxidative stress and neuroinflammation are known to play a critical role in dementia. This project will study the association of apoD to inflammatory and oxidative stress markers in Alzheimer’s disease and Frontotemporal Dementia, two major forms of dementia. It will also examine the impact of apoD on disease pathology. Hence this project will lead us to therapeutic potentials of apoD.
Implications Of Retinal Neurodegeneration In Alzheimer's Disease

Summary
Recent research has shown that “early signs” of Alzheimer ’s disease (AD) can be detected in the eyes. My research focus is to determine which particular changes in the retina are associated with AD. I will also investigate if blocking the production of beta amyloids (proteins produced in AD) in the eye will indeed help reduce their load in the brain and hence delay the onset of AD. Results from this research maybe used for early diagnosis and future medicinal studies that target the eye in AD.
Neuroprotective Functions Of Autophagy Regulators In Alzheimer's Disease

Summary
The accumulation of the beta amyloid protein has a central role in AD and enhancing its removal improves memory loss in animal AD models. This project builds on my recent finding of regulators of a cell housekeeping system, “autophagy” which accelerate removal of beta amyloid in cells. This study will advance knowledge into the protective functions of the autophagy regulators in reducing AD symptoms. Findings from this work might provide the basis for developing effective anti-AD therapeutics.
In Vivo Assessment Of The Role Of Aggregated Tau In Preclinical And Prodromal Alzheimer's Disease

Summary
Subtle changes in the brain precede an Alzheimer’s disease (AD) diagnosis by 20-30 years. These changes provide an incredible opportunity to diagnose and treat AD; however, our understanding of them, remains limited. We aim to use new imaging technologies to investigate these subtle changes in the preclinical AD brain. This will give us a greater understanding of how these early changes effect AD progression and whether we can use this information to improve the diagnosis and treatment of AD.
