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.

Resolving Human Immunodeficiency Virus (HIV) Transmission
Funder
National Health and Medical Research Council
Funding Amount
$745,213.00
Summary
To increase the breadth of HIV prevention strategies, it is imperative that we biologically understand how HIV enters our bodies. Through two unique clinical cohorts, we will determine why circumcision is protective and how a commonly acquired sexual transmitted infection (human papilloma virus) can increase HIV transmission.
Developing And Implenting An Ethical Framework For HIV Phylogenetic Analysis In Australia

National Health and Medical Research Council
Funding Amount
$537,855.00
Summary
Overseas, many countries are using genetic analysis to detect clusters of HIV transmission. This is an important part of reducing the number of new HIV infections, and making sure that all people with HIV receive timely medical care. In partnership with HIV community organisations and public health policy makers, we will provide the first evidence-base for the public health utility of real-time HIV genetic analysis in the Australian setting.
The Human Immunodeficiency Virus (HIV) is a virus that infects and kills the cells of your immune system. This infection eventually leads to the Acquired Immune Deficiency Syndrome (AIDS). An important aspect in preventing infection is to study how HIV enters immune cells and how infection spreads. Our lab is researching drugs to block the entry of HIV in immune cells, which can hopefully be used together with existing anti-HIV drugs to slow down the spread of the virus and the onset of AIDS.
Understanding The Establishment Of HIV Reservoirs And Development Of HIV Eradication Strategies

Funding Amount
$380,891.00
Summary
Understanding why, when, how and at what pace the HIV virus hides and establishes itself in one's body will allow us to design new ways for preventing and eliminating this reservoir of hidden HIV. As a clinician scientist in HIV and infectious diseases, I will drive clinical studies to explore the kinetics of HIV in patients who recently acquired HIV, those who start HIV treatment early, and those chronically infected with HIV so as to investigate novel means to minimise HIV hiding spots.
Characterize The Post-entry Events Of HIV Infection

Funding Amount
$605,190.00
Summary
For HIV to successful infect a target cell, it must properly remove the outer layers of its protective gears (outer viral protein coats) to allow the viral genetic materials to be replicate (duplicate and multiplied) for the generation of their ‘offspring viruses’. This process is known as viral uncoating, and it is arguably one of the least understood areas of HIV. In this proposal, we will use a number of complementary state-of-the-arts research tools to characterize the HIV uncoating process.
This project involves a unique interdisciplinary approach combining bioinformatics, biostatistics and mathematical biology to better understand the dynamics of infection and immunity. Using data from in vitro studies, animal models, and human infections, I aim to understand immune control and pathogen growth and evolution in HIV and malaria infection.
Rapid HIV-1 Tropism Testing Using Novel, Soluble Mimics Of The HIV-1 Coreceptors CCR5 And CXCR4
Funder
National Health and Medical Research Council
Funding Amount
$163,426.00
Summary
This proposal seeks to develop an inexpensive assay to determine whether HIV patients will benefit from treatment with new drugs referred to as CCR5 antagonists. These are effective against HIV strains that use the CCR5 coreceptor, therefore a patient�s HIV coreceptor usage must be assessed before commencing therapy. Current assays are complicated, slow and expensive. Using novel, soluble mimics of the coreceptors we will develop an ELISA based test that can be operated using standard equipment.
Protocol Development For Study Design And Analysis In HIV Latency Research
Funder
National Health and Medical Research Council
Funding Amount
$73,836.00
Summary
This study will aim to improve the development and analysis of HIV research studies. Currently HIV studies looking at the virus that remains in the body even when taking medication for HIV are too small to produce consistent results. This research will look at the statistical methods used to analyse these studies and find the best method for analysis, as well as developing guidelines for choosing appropriate numbers of study participants in future studies to allow results to be more accurate.
Silent Mutations In The HIV-1 Reverse Transcriptase Selected During Antiretroviral Therapy
Funder
National Health and Medical Research Council
Funding Amount
$555,325.00
Summary
This project seeks to determine the role of silent mutations in the HIV reverse transcriptase that are selected during drug therapy in HIV infected individuals on HIV fitness, reverse transcriptase function and the emergence of drug resistance. This study will increase our understanding of the mechanisms by which the virus evades the effects of antiretrovirals and will provide a rationale for deciding on the best drug combinations for use in patients infected with specific HIV strains (clades).
Improved Health Outcomes For People Living With HIV

Summary
Despite the success of antiviral therapy for HIV infection, HIV cannot be cured and treatment is life long. In addition, there are complications in patients on long term antiviral therapy due to impaired immune recovery. This grant will identify strategies to eliminate HIV from latently infected cells that persist in patients on antiviral therapy as well as identify novel ways to improve the immune response to antiviral treatment for patients with HIV infection as well as patients co-infected wi ....Despite the success of antiviral therapy for HIV infection, HIV cannot be cured and treatment is life long.
