Summary
Leishmania are protozoan parasites that cause a number of important diseases in humans, afflicting more than 12 million people worldwide. There are currently few drugs that target infectious disease causing stages of these parasites. We have recently shown that Leishmania parasites accumulate a highly unusual sugar polymer when they infect mammalian cells, which appears to be important for infectivity.

There are currently few drugs that target infectious disease causing stages of these parasites. We have recently shown that Leishmania parasites accumulate a highly unusual sugar polymer when they infect mammalian cells, which appears to be important for infectivity. In this proposal , we will investigate how this sugar polymer is made, identify enzymes involved in its synthesis and develop new chemical tools for generating highly specific inhibitors of Leishmania sugar biosynthesis. This project will provide new insights into processes that are essential for the survival and infectivity of an improtant group of human pathogens, and lead to the development of new classes of enzyme inhibitors with anti-parasite activity.Read moreRead less
Sustainable Control And Elimination Of Neglected Tropical Diseases In The Asia-Pacific

Funding Amount
$428,065.00
Summary
The neglected tropical diseases (NTDs) are of major public health importance. Parasitic worms are the most common infecting almost a third of the world’s population. Multi-component integrated intervention strategies will be required for sustainable control and elimination of NTDs in the Asia-Pacific. I will develop and lead the first Australian Centre for Population Health Research on NTDs that will undertake research into their epidemiology, control and elimination.
Mechanisms Of In Vivo Modulation Of Granulomatous Inflammation In Human Schistosomiasis

Funding Amount
$276,598.00
Summary
Schistosomiasis is a serious parasitic disease responsible for up to 300,000 deaths annually. The cause are blood flukes that produce considerable disease severity, resulting from host inflammation against the parasite eggs lodging in the liver, giving rise to fibrosis, liver damage, enlarged spleen and death. The pathogenesis is regulated by molecules called cytokines and this project will unravel the mechanisms that regulate disease progression to the severe forms of chronic schistosomiasis.
Impact Of The Three Gorges Dam On Transmission And Future Control Of Human Schistosomiasis In China

Funding Amount
$1,420,135.00
Summary
A million Chinese have schistosomiasis or snail fever. When the Three Gorges Dam on the Yangtze River is fully operational, considerable environmental-ecological changes will result, increasing spread of this parasitic disease. In a unique study we will assess the impact of the Dam on schistosomiasis, and test and model a series of options for its control. The findings will be important for China and other areas where schistosomiasis occurs and where similar dams are planned or are under way.
Schistosomiasis is a major public health problem in the Philippines with approximately 6.7 million people at risk of infection. Mass human chemotherapy has formed the cornerstone of control for decades but has failed to control the disease. Transmission reduction is a key step towards elimination and integrated interventions should target both definitive and intermediate host transmission pathways. We propose to trial integrated control strategies for the disease and expect the outcomes to have ....Schistosomiasis is a major public health problem in the Philippines with approximately 6.7 million people at risk of infection. Mass human chemotherapy has formed the cornerstone of control for decades but has failed to control the disease. Transmission reduction is a key step towards elimination and integrated interventions should target both definitive and intermediate host transmission pathways. We propose to trial integrated control strategies for the disease and expect the outcomes to have broader implications for Southeast Asia.Read moreRead less
Developing Core Bioinformatics Capacity At The Australian Institute Of Tropical Health And Medicine

Funding Amount
$318,768.00
Summary
Cost-effective next generation sequencing is now a reality, meaning the bottleneck for research projects is shifting from data generation to data analysis. Researchers at the Australian Institute of Health and Tropical Medicine (AITHM) are engaged in an increasing number of high-impact projects that require timely access to bioinformatic best-practices methodologies. This proposal outlines a strategy to support these projects by developing and expanding the bioinformatics capacity within AITHM.
I am a clinician-scientist in infectious and tropical diseases, working towards the better understanding of the pathophysiology of malaria and other tropical diseases of public health importance in our region, and new ways of prevention and treatment.
Improving Health Outcomes In The Tropical North: A Multidisciplinary Collaboration
Funder
National Health and Medical Research Council
Funding Amount
$5,997,916.00
Summary
Improving Health Outcomes in the Tropical North will strengthen partnerships with research institutions in the NT, Qld, WA, NSW, Vic and SA, by undertaking a research agenda that will help close the gap in Indigenous health disadvantage, protect the north from emerging infectious threats and engage regional neighbours. We will establish a northern Australian network that incorporates Indigenous engagement, mentoring and knowledge translation, and facilitates collaboration with southern partners.
