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.

Peptide Toxins From Animal Venoms Specifically Targeting Voltage-gated Sodium Channels As Novel Analgesics And Pesticides
Funder
National Health and Medical Research Council
Funding Amount
$316,449.00
Summary
This project aims to understand how certain animal toxins that cause analgesic and pesticidal effects in model animals interact with biological ion channels in atomistic detail using computational techniques. By understanding the detailed molecular interactions involved in the binding of the toxins to channels, toxin variants with improved potency and specificity may be designed as promising templates for novel analgesics and pesticides.
The Proteomics Of The Von Hippel-Lindau (VHL) Tumour Suppressor Protein
Funder
National Health and Medical Research Council
Funding Amount
$292,639.00
Summary
This project primarily intends to identify novel modifications to the von Hippel-Lindau (VHL) protein which plays a role in tumour suppression and blood vessel growth. It is the purpose of this project to characterise these changes to VHL and ultimately, understand what these changes mean to the function of VHL protein, and modulate them to ameliorate VHL disease.
Structural Characterisation Of SNARE Protein Complexes Involved In Insulin-regulated Glucose Transport

National Health and Medical Research Council
Funding Amount
$320,803.00
Summary
Insulin-regulated glucose transportation is defective in type 2 diabetes, a disease that is a major health problem worldwide and in some cases can lead to death. The aim of this work is to investigate the molecular structure and function of proteins critical to the transportation and delivery of glucose to muscle and fat cells, which will lead to the validation of new therapeutic targets and the development of new treatments for diabetes.
Structural Investigation Into The Regulation Of The Colony Stimulating Factor Receptor, C-FMS.
Funder
National Health and Medical Research Council
Funding Amount
$287,321.00
Summary
The colony stimulating factor receptor, c-FMS is a member of a family of protein signalling molecules expressed on the cell surface that are implicated in the development of serious diseases in humans, such as inflammatory diseases and cancer. A number of important proteins bind to and regulate c-FMS in different ways. I intend to visualise these interactions to further understand how c-FMS activity is controlled by alternative means.
Proteins Involved In HIV Infection And Host Defense
Funder
National Health and Medical Research Council
Funding Amount
$323,244.00
Summary
I am a biochemist focused on answering the question: why is it that humans are susceptible to HIV infection, while certain monkeys are resistant? It is known that these monkeys have evolved proteins which can target and destroy the virus, but the equivalent human proteins don’t work against HIV. I intend to compare the monkey and human proteins to understand how the monkeys destroy the virus and why the human protein is defective. These studies will inform the next generation of HIV treatment.
How Do TRIM21 And TRIM5α Execute Dual Antiviral Effector And Signalling Functions?
Funder
National Health and Medical Research Council
Funding Amount
$344,724.00
Summary
We encounter millions of potential pathogens each day that must be detected and disarmed by the immune system. Recently, two antiviral proteins, present inside cells, were shown to both detect viruses, alerting neighbouring cells to the infection, and target the viruses for destruction. These two functions provide important protection against viral infection and this research aims to understand at a molecular level, how these dual antiviral functions are coordinated.
Directed Molecular Evolution Of G Protein-coupled Receptors For Stable And Functional Expression In Escherichia Coli
Funder
National Health and Medical Research Council
Funding Amount
$383,479.00
Summary
Approximately half of all prescription drugs on the market act on G protein coupled receptors (GPCRs). The mechanisms underlying GPCR function are mainly unknown due to a lack of structural information. No solved structures exist for any of the estimated 800 human GPCRs, making it difficult to design new drugs. By applying advanced protein engineering techniques I aim to produce human GPCRs in bacteria to ultimately acquire structural information, which will enable novel drug development.
Alzheimer's, Huntington's and Parkinson's diseases involve the formation of protein aggregates, termed amyloid. The formation of amyloid leads to cell death and neurodegeneration. The most important cellular events perturbed by the formation of amyloid aggregates are unclear. Recent evidence suggests that sterols (including cholesterol) have an important role in cellular toxicity. This study will examine the molecular basis for this, enhancing our understanding of the amyloid diseases and could ....Alzheimer's, Huntington's and Parkinson's diseases involve the formation of protein aggregates, termed amyloid.
