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.

Probing membrane rafts using surface-selective multi-dimensional microscopy. The results of this project will provide fundamental insights into the role played by domains in cell membranes in the regulation of membrane protein function. These insights will create new avenues in the biotechnology industry for development of novel therapeutics aimed at disruption of membrane protein-protein interactions that cause aberant cell signalling in disease states such as cancer.
Zinc finger domains as scaffolds for protein engineering. While great advances have been made in pharmaceutical design and discovery, it is clear that new types of drugs are needed for the better management of a wide range of diseases (e.g. cancers, autoimmune diseases, viral infections). Many of these diseases arise from inappropriate interactions between intracellular biological macromolecules. My aim is to develop a range of novel therapeutic proteins based on naturally existing zinc-binding ....Zinc finger domains as scaffolds for protein engineering. While great advances have been made in pharmaceutical design and discovery, it is clear that new types of drugs are needed for the better management of a wide range of diseases (e.g. cancers, autoimmune diseases, viral infections). Many of these diseases arise from inappropriate interactions between intracellular biological macromolecules. My aim is to develop a range of novel therapeutic proteins based on naturally existing zinc-binding protein domains with the goal of selectively blocking these inappropriate interactions. Additionally, these engineered proteins have potential uses as biochemical tools such as to help delineate the functions of natural proteins with no known functions.Read moreRead less
New technology for the delivery of peptide-based T-cell vaccines for tumour immunotherapy. This project is dedicated to finding simple methods for vaccinating humans and animals against a wide variety of cancers. Should this be achieved millions of Australians will be protected from the devastating consequences of cancer. Consequently there will be great benefits socially, medically and economically.

Structural investigations into the regulation of programmed cell death. One in three men and one in four women in Australia will develop cancer by the age of 75 at current incidence rates. At its heart, cancer is a disease of uncontrolled cell proliferation. One of the body's main defence mechanisms against excess cell proliferation is Programmed Cell Death, a process which becomes dysfunctional in cancer cells. This work will provide three dimensional images of the machinery that controls Progr ....Structural investigations into the regulation of programmed cell death. One in three men and one in four women in Australia will develop cancer by the age of 75 at current incidence rates. At its heart, cancer is a disease of uncontrolled cell proliferation. One of the body's main defence mechanisms against excess cell proliferation is Programmed Cell Death, a process which becomes dysfunctional in cancer cells. This work will provide three dimensional images of the machinery that controls Programmed Cell Death. This information is critical for the development of drugs designed to re-initiate Programmed Cell Death in cancer cells.Read moreRead less
Structural analysis of membrane proteins using template-mediated crystallization. A new frontier technology will be developed in the form of a systematic crystallization pipeline for membrane proteins. This high throughput monolayer template technology is particularly suited for the structure determination of proteins that are otherwise difficult to crystallize and has clear commercial potential. Membrane protein structures are themselves of value to the biotechnology and pharmaceutical industry ....Structural analysis of membrane proteins using template-mediated crystallization. A new frontier technology will be developed in the form of a systematic crystallization pipeline for membrane proteins. This high throughput monolayer template technology is particularly suited for the structure determination of proteins that are otherwise difficult to crystallize and has clear commercial potential. Membrane protein structures are themselves of value to the biotechnology and pharmaceutical industry for targeted drug design, which could realise benefits in the form of novel medical treatments and reduced side effects. The monolayer template technology will also extend the capabilities of the National Cryo-EM facility, the infrastructure of which, is open for all Australian researchers. Read moreRead less
Development of novel therapies for the treatment of cancer. Both aging and obesity are significant risk factors for cancer and are becoming a burden on the health care budget. The proposed novel cancer therapy will improve current cancer treatments by enhancing their efficacy, thereby reducing the required dose and minimizing side effects. Such an outcome would not only benefit the well being of the individual but would achieve significant health care cost savings.

This facility will provide Australian researchers with unrivalled access to advanced cell visualisation and analysis tools, which until very recently were only available to the pharmaceutical industry and large US and European institutions. The facility will allow new approaches to identifying novel natural products and understanding cell signalling pathways. Knowledge of these pathways and the identification of molecules that can affect them are keys to understanding normal cellular physiology and identifying drug-like molecules able to inhibit malfunctioning pathways found in different disease such as cancer. The facility will accellerate drug discovery and basic research in cell biology and underpin National Research Priorities.Read moreRead less

We propose a multi-disciplinary approach to this fundamental biological problem and have established collaborations with experts in the USA, UK and Austria. Benefits from this research program fall into two discrete types. Firstly, detailed knowledge of the mechanism what is now a poorly understood biological process of cellular membrane assembly, with the prospects for using the knowledge for intervention into diseases such as cancer. Secondly, excellent outcomes are provided for the training of postgraduate students and research staff. This project entails cutting edge technology, and the development of skills not common in Australia.Read moreRead less
Evolution of a protein fold from toxin to physiological regulator: an endogenous potassium channel blocker in humans. A potassium channel blocking peptide employed by sea anemones as a toxic component of their venom is also found in proteins from a number of higher organisms, including man. In most of these proteins the function of this toxin domain is unknown. This project aims to define the structure and function of this domain in a human protein, matrix metalloprotease 23, which has possible ....Evolution of a protein fold from toxin to physiological regulator: an endogenous potassium channel blocker in humans. A potassium channel blocking peptide employed by sea anemones as a toxic component of their venom is also found in proteins from a number of higher organisms, including man. In most of these proteins the function of this toxin domain is unknown. This project aims to define the structure and function of this domain in a human protein, matrix metalloprotease 23, which has possible roles in prostate and other cancers. Our results will not only be of interest in tracing the structural and functional evolution of this toxin domain but will also provide valuable clues to its role in both the normal physiological function of matrix metalloprotease 23, as well as its potential pathological role in cancer.Read moreRead less
