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.

Steroidal control of male meiosis. This innovative project will study a complex cellular process (meiosis) essential for sperm development and sexual reproduction. Collaborations and novel experimental design provide cutting edge techniques and opportunity for Australian researchers to contribute important discoveries to this field. We aim to provide new knowledge of steroid-dependent molecular factors that may activate (or inhibit) meiosis. Such novel information may significantly impact divers ....Steroidal control of male meiosis. This innovative project will study a complex cellular process (meiosis) essential for sperm development and sexual reproduction. Collaborations and novel experimental design provide cutting edge techniques and opportunity for Australian researchers to contribute important discoveries to this field. We aim to provide new knowledge of steroid-dependent molecular factors that may activate (or inhibit) meiosis. Such novel information may significantly impact diverse areas related to controlling mammalian reproductive development, such as health and well-being (a healthy start to life, fertility control), farming and agriculture (livestock production, pest management) and the Australian environment (conservation, pest management).Read moreRead less
Structural and functional characterisation of compounds that inhibit the malarial aminopeptidases. Malaria is the world's most prevalent parasitic disease. Due to the rapid spread of drug resistant parasites there is a need to develop new antimalarial drugs. In this proposal we will characterise new targets and novel methods of inhibition that will form the basis of a new mechanism for antimalarial drugs.
Proteolysis of binding protein complexes regulates bioavailability of insulin-like growth factor (IGF). We aim to determine how growth factors kept inactive in complexes in the blood can become free and active. The fundamental knowledge gained will help us understand the regulation of growth factors' availability to tissues and develop novel or more effective delivery systems for therapeutic growth factors that could impact on several conditions including diabetes, growth disorders and critical ....Proteolysis of binding protein complexes regulates bioavailability of insulin-like growth factor (IGF). We aim to determine how growth factors kept inactive in complexes in the blood can become free and active. The fundamental knowledge gained will help us understand the regulation of growth factors' availability to tissues and develop novel or more effective delivery systems for therapeutic growth factors that could impact on several conditions including diabetes, growth disorders and critical illness. This project therefore benefits Australia at two levels: by maintaining our international leadership in the study of these important growth-regulatory molecules, and by providing a better understanding of physiological mechanisms that might benefit the health of Australians and provide opportunities to develop novel therapeutics.Read moreRead less
Pathogenesis of Alzheimer's disease: Dissecting synaptosomal dysfunction in transgenic animal models. There is no cure for Alzheimer's disease (AD). This project will dissect pathogenic mechanisms, identify new drug targets, and develop treatment strategies, all of which will be patented and eventually lead to a decrease in health costs in Australia. This research clearly falls under the national research priority of promoting and maintaining good health. Our findings are expected to benefit pat ....Pathogenesis of Alzheimer's disease: Dissecting synaptosomal dysfunction in transgenic animal models. There is no cure for Alzheimer's disease (AD). This project will dissect pathogenic mechanisms, identify new drug targets, and develop treatment strategies, all of which will be patented and eventually lead to a decrease in health costs in Australia. This research clearly falls under the national research priority of promoting and maintaining good health. Our findings are expected to benefit patients in addition to those suffering from AD, as pathocascades and pathogenic mechanisms are shared between a range of neurodegenerative disorders.

Cellular and molecular mechanisms for gut homeostasis in mammals. Certain molecules are responsible for gut homeostasis. This project aims to develop new tools to manipulate the cellular and molecular pathways around these molecules, which should provide benefit for human and animal health. This project will test whether the basis of many health conditions is disrupted gut homeostasis, through changes in diet and our gut bacteria.
Characterisation of a novel neural-specific ATPase in cholesterol transport. Ageing is determined by both genetic and metabolic factors. To a large part, the detailed mechanisms of ageing remain to be unexplored. Genetically, the timing of cell ageing entails the loss of telomeres (tips of chromosomes). However, the buildup of metabolic wastes resets the timing prematurely. Metabolic products accumulate from excess production or a shortfall of removal activity, which occurs in the various parts ....Characterisation of a novel neural-specific ATPase in cholesterol transport. Ageing is determined by both genetic and metabolic factors. To a large part, the detailed mechanisms of ageing remain to be unexplored. Genetically, the timing of cell ageing entails the loss of telomeres (tips of chromosomes). However, the buildup of metabolic wastes resets the timing prematurely. Metabolic products accumulate from excess production or a shortfall of removal activity, which occurs in the various parts of ageing cells in tissues such as brain. Traffic jams of cholesterol transport in the secretory pathway induce early ageing of the nerve cells. We investigate a novel mechanism controlling cholesterol transport in nerve cell ageing.Read moreRead less
Unlocking malaria invasion by ultraresolution microscopy. This project describes the microscopic analysis of malaria-causing parasites invading human blood cells. The project aims to better understand how this invasion works and to understand how it might be inhibited.
Iron accumulation in the nematode C.elegans: a model of ageing. This project will investigate the role of biological metals in the process of ageing, the causes of which remain unresolved. The practical outcomes for society are broad; beyond improving understandings of the basic biology of ageing, this study will provide new insight and approaches that can be used to optimise lifespan.
The biogenesis of bacterial outer membranes: how bacteria build their surface coating. This project will determine how bacteria build their outer membranes. The outer membrane protects 'probiotic bacteria' in the human intestine and enables 'pathogenic' bacteria to cause infectious diseases. The project presents outstanding training opportunities with the use of cutting edge technology and the development of skills not common in Australia.
