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.

Processes Underlying Establishment And Maintenance Of The Latent HIV Resevoir And Potential Impact Of Integrase Inhibitors
Funder
National Health and Medical Research Council
Funding Amount
$318,044.00
Summary
Therapy for HIV-infected individuals is currently able to control the growth of the virus, but cannot eradicate the viral infection. This is due to a pool of CD4+ T lymphocytes which contain HIV DNA in a latent state, ready to reactivate as soon as therapy is interrupted. This project aims to better understand how this pool of latently infected CD4+ T lymphocytes is established and maintained, particularly how it is linked to the essential T cell survival signal from interleukin 7.
Understanding The Side Effects Of HAART In HIV Patients
Funder
National Health and Medical Research Council
Funding Amount
$387,489.00
Summary
Combination therapy has dramatically improved the life expectancy of people living with HIV. However, the long term side effects of these medications can be significant. Not everyone treated with the same drugs suffers similar side effects. This project seeks to unravel factors that lead a given individual to experience particular side effects. Understanding why medication side effects occur will be critical in finding safer ways to treat HIV.
Bisphosphonate Therapy With Zoledronate Or Tenofovir Switching To Improve Low Bone Mineral Density In HIV-Infected Adults: A Strategic, Randomised Trial
Funder
National Health and Medical Research Council
Funding Amount
$716,300.00
Summary
Most HIV+ Australians receive tenofovir, a ‘preferred’ drug in all HIV treatment guidelines, and may do for decades, as HIV therapy is lifelong and because there are very few new HIV drugs. 40% of HIV+ adults have low bone density and HIV+ adults experience more fractures. Of all HIV drugs, tenofovir causes the most bone loss. This trial compares two approaches: a drug to improve bone density and switching tenofovir to another drug. This ‘treat versus switch’ approach is a world-first for HIV.
Enhancing The Cascade Of HIV Care To Maximise The Prevention Benefits Of Antiretroviral Therapy For Populations Living With HIV
Funder
National Health and Medical Research Council
Funding Amount
$344,644.00
Summary
Antiretroviral drugs are effective at preventing death and illness for populations with HIV and preventing HIV transmission. I will undertake a series of studies to measure the impact of current antiretroviral treatment to prevent both illness and new infections in Australia. I will also undertake a series of studies to increase HIV testing, diagnose HIV earlier, and improve people’s linkage and retention HIV in care and evaluate the impact of these interventions on HIV transmission.
The Pharmacokinetic, Pharmacodynamic And Pharmacogenomic Outcomes Of Reduced Dosage Of Efavirenz: The Encore1 Study
Funder
National Health and Medical Research Council
Funding Amount
$1,234,943.00
Summary
Our primary aim is to assess blood concentrations of a drug called efavirenz, an important drug used in the treatment of HIV infection and associate these with variability of genes that control metabolism of the drug. A better understanding of gene variability and how it relates to safety and efficacy outcomes at a reduced, compared to a standard dose of efavirenz could support improved treatment of HIV disease.
Eliminating Excess Cardiovascular Risk In People Living With HIV
Funder
National Health and Medical Research Council
Funding Amount
$402,396.00
Summary
People living with HIV have two times the risk of having a heart attack compared with the general population. Some of this risk is due to damage cause by inflammation that the HIV virus stimulates, but side effects of anti-HIV medications also play a part. This project will try two new strategies aimed at reducing inflammation and blocking the side effects of anti-HIV medications with the aim of reducing the risk of heart attack in people with HIV.
The Future Of HIV Care - Long Term Remission And Eliminating Co-morbidities
Funder
National Health and Medical Research Council
Funding Amount
$577,189.00
Summary
Despite the great successes in antiretroviral therapy (ART) in reducing HIV-associated mortality, treatment is life long and there is no cure. The major barrier to a cure for HIV is the persistence of long lived latently infected cells on ART. Over the next five years I will discover, develop, optimise and evaluate novel interventions to eliminate latently infected cells, long lived infected cells in the liver and enhance HIV-specific immunity through immunotherapy.
Improving The Therapeutic Use Of Anti-infective Agents: Application Of Pharmacometrics For Rational Dosing Regimen Design
Funder
National Health and Medical Research Council
Funding Amount
$313,390.00
Summary
There is no field of medicine in which the individualisation of medicines is more important than in infectious diseases – appropriate doses must be administered to maximise efficacy and to minimise side effects and the emergence of drug-resistance. This fellowship will use the emerging science of pharmacometrics to investigate factors contributing to the variability in response to anti-infective medications and to optimise dosing regimens for the best use of these drugs in clinical practice.
Developing And Implementing Systems To Optimise Treatment, Care And Support Among People Diagnosed With HIV
Funder
National Health and Medical Research Council
Funding Amount
$1,021,439.00
Summary
Immediate treatment of people diagnosed with HIV infection has become a key public health intervention, based on recent evidence confirming treatment suppresses the virus to undetectable levels, and effectively eliminates the risk of transmission to sexual partners. Our partnership will identify and address barriers to accessing specialist HIV care and starting treatment among people recently diagnosed with HIV, and will contribute to Australia’s goal of ending HIV transmission by 2020.
