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.
Cluster Randomised Trial Comparing One Versus Two Doses Of Ivermectin For Mass Drug Administration To Control Scabies

Summary
Scabies is a common skin disease in developing countries, in particular in the Pacific region. In the Western Province of Solomon Islands, one in two children suffer from the infestation, and 20% of the population. We know that mass drug administration with two doses of oral ivermectin is effective to reduce the burden of scabies in the community. We now propose a study to determine whether one single dose is as effective. This would have major public health benefits.
I am a molecular parasitologist exploring parasitism in blood-feeding human helminths, with a particular focus on the molecular biology of parasite feeding and immune evasion. I am utilizing this information to develop anti-helminth recombinant vaccines a
Does Mass Drug Administration For Scabies Result In Control Of Serious Bacterial Complications? A Proof Of Concept Towards Global Elimination.

Summary
Scabies is common skin disease in developing countries, in particular in the Pacific region. In Fiji, one in two children suffer from the infestation, which affects over 20% of the population. A recent study conducted in Fiji on 2000 people showed that mass drug administration (MDA) with oral ivermectin is a safe and effective way to reduce the burden of scabies in the community. We will expand the MDA program to 100,000 people, the largest study of MDA ivermectin for scabies ever undertaken.
Parasitic and viral infections involving the retina are serious eye conditions that are poorly understood and lack effective treatments. My PhD studies will focus on how human retinal cells fight infections caused by the Toxoplasma parasite, and dengue and Ebola viruses. The results of my investigations will inform the development of better treatments for these blinding eye diseases.
The Role Of Mucosal-Associated Invariant T Cells In Protective And Aberrant Immunity

Summary
Despite their prevalence and potential therapeutic value, MAIT cells remain the least studied of all T cells. This program seeks to do paradigm shifting research into the role of MAIT cells in protective immunity to microbes and allergies. Thereby this project will significantly advance fundamental knowledge on MAIT cell biology and could furnish novel immunotherapeutic agents with an enormous potential as alternatives to microbial and allergy treatments, areas of tremendous clinical need.
Genomic-based Tools To Support The Control Of Urogenital Schistosomiasis And Hepatic Opisthorchiasis

Funding Amount
$419,180.00
Summary
Over 100 million people are affected by parasitic flukes that promote malignant tumours. Parasite control depends on a single drug, making resistance an imminent threat. I will deliver new genomic tools to unravel the complex interactions between parasites and humans, and explore parasite population diversity on a continental scale. I will then prioritise a panel of anti-parasitic drug targets and vaccine candidates to deliver the next generation of interventions against parasitic diseases.
Function And Inhibition Of Plasmepsin V In Targeting Malaria Virulence Proteins Into Human Erythrocytes

Summary
Malaria parasites dramatically renovate infected erythrocytes to survive and evade the host immune system by delivering hundreds of exported parasite proteins into the cell. The parasite protease Plasmepsin V is essential for protein export. We aim to develop potent inhibitors of this protease in the hope of blocking its function and killing the parasite. We also aim to discover the components of the trafficking pathway after cleavage by Plasmepsin V that sorts virulence proteins to the host cel ....Malaria parasites dramatically renovate infected erythrocytes to survive and evade the host immune system by delivering hundreds of exported parasite proteins into the cell.

Summary
Parasitic worms have an amazing ability to manipulate the immune system, and our research group recently discovered how they may hold the key for treating inflammatory diseases such as Coeliac Disease. The aim of my research is to further develop this novel therapy in a clinical trial and study the mechanism of how worms control the immune response, including identifying the molecules that the worm produces that could be produced as a pill-based medication for treating coeliac disease.

Summary
Malaria parasites cause profound human disease through infection of the red blood cell. How parasites break into the red cell is incompletely understood. Foremost, the parasite must induce radical changes in its structural integrity to enter, but to date no study has been able to precisely map these cellular events. In this research program we aim to dissect the entire process using state-of-the-art imaging, molecular biology and proteomics to shine new light on this key step in malaria disease ....Malaria parasites cause profound human disease through infection of the red blood cell.
