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.

Identifying Malaria PfEMP1 Proteins That Elicit Antibodies Associated With Protection From Cerebral Malaria
Funder
National Health and Medical Research Council
Funding Amount
$494,117.00
Summary
The malaria parasite changes molecules it uses to cause disease, this alters its appearance so it can escape people's immune response. However some of these molecules are similar in the parasites that cause the most severe disease. We aim to identify these similar molecules because they may make useful vaccines for protecting people from severe malaria disease.
Trafficking Of The Major Virulence Protein To The Host Cell Surface In Malaria Parasite-infected Erythrocytes
Funder
National Health and Medical Research Council
Funding Amount
$658,164.00
Summary
The malaria parasite infects human red blood cells and causes them to stick to blood vessels in the brain, inducing coma. This causes the deaths of ~2 million children each year. We will use cell biology techniques to manipulate malaria parasites to unravel the details of the molecular ticketing system that the parasite uses to get its adhesive proteins onto the red blood cell surface. The ability to interfere with this process would greatly decrease the impact of this major human pathogen.
Exported Malaria Kinases And Red Blood Cell Remodeling
Funder
National Health and Medical Research Council
Funding Amount
$408,710.00
Summary
Malaria is a serious disease affecting half the world's population and every year, more than a million people (mostly children) die as a result of the infection. Our work will help us to understand how malaria parasites alter human red blood cells and make them stick in organs such as the brain. Preventing infected red cells from becoming stiff and sticky by developing new drugs will open up new lines of attack to combat this devastating disease.
Mechanism Of Neurological Complications In Cerebral Malaria
Funder
National Health and Medical Research Council
Funding Amount
$53,609.00
Summary
Malaria kills 1 million young children every year. About the same number are saved by treatment with anti-malarial drugs but have brain damage, leading to problems of understanding, learning or memory. The processes in the brain that lead to these changes are unknown. I will investigate a biochemical pathway that is activated during malaria infection, because I propose that this may cause the brain damage that leads to the long-term cognitive problems in survivors.
Functional Resolution Of PTEX, The Exporter Of Virulence Factors In Malaria Parasites.
Funder
National Health and Medical Research Council
Funding Amount
$625,212.00
Summary
Almost half a million people die each year of malaria and nearly half the world’s population are at risk. To eliminate malaria this century we will need new drugs and vaccine to fight the disease. One potential drug target are the molecular gateways called PTEX, that are used by parasites to export virulence proteins into their human host cells. This grant aims to understand how the PTEX molecular machines work so we can develop new drugs to block them and kill the parasites.
The transmission of malaria is dependent on gametocytes, the sexual stages of parasite development that are taken up by mosquitoes when feeding on an infected person. While gametocytes are not responsible for disease symptoms, it is clear that malaria eradication is not be possible without an understanding of their biology and the tools to prevent transmission. My research focuses on understanding the biology of gametocytes and identifying new drug targets for transmission blocking strategies.
Griseofulvin, A Novel Host-directed Antimalarial Drug
Funder
National Health and Medical Research Council
Funding Amount
$461,551.00
Summary
This grant is for a Phase II clinical trial to test an FDA & TGA approved drug for a new use as an antimalarial drug. The parasite uses an enzyme from the human RBC to help it replicate & early trials show this drug appears to disrupt the life cycle of the parasite. This Phase II clinical trial will test the drug on human subjects, & if successful, the drug will be a new and novel way in which to treat and prevent malarial infections in humans.
Malaria infects millions of people worldwide causing serious morbidity and mortality. However, individuals do not develop natural immunity to malaria even after years of exposure to the parasite. There have be a multitude of attempts to make a vaccine , with products going to clinical trials, but no vaccine is able to provide adequate protection for the long term. We recently showed that Plasmodium had evolved a mechanism to kill cells that protect in the long-term.

Malaria In Pregnancy: Exposure, Immunity And Complications
Funder
National Health and Medical Research Council
Funding Amount
$549,723.00
Summary
Increasing malaria control efforts may lead to lack of exposure needed to develop immunity. We will use plasma samples from Africa, PNG and Asia, and measures of immunity we have developed, to discover (1) which are the most important protective immune responses and (2) how are these affected by changing exposure or new drugs. Overall, we hope to identify markers of protective immunity that can be used to identify women at most risk of malaria in pregnancy and its complications

Summary
EVIMalaR is a European Virtual Institute for Malaria Research that combines 42 of the European Union’s leading malaria research groups plus 4 Africans, 1 Indian institution, and 1 Australian.

EVIMalaR faculty will combine expertise to produce a Network of Excellence that enhances and harmonises experimental approaches through shared technological platforms, exchange visits, shared PhD students, shared resources such as databases, reagent banks and protocols across pathology, infection, immunology and biochemistry. Malaria is a global problem with no single solution. A large, but sometimes disjointed, research community is addressing the problem, but more collaboration is vital. OzEMalaR will link 34 Australian labs with 47 European, African and Indian malaria researchers. Funding will enable exchange of modern technologies by supporting early career researchers (PhD and postdocs) from Australia to work and be trained in top European labs. European trainees will work and be trained by Australian malariologists using reciprocal EU supportRead moreRead less
