I am a molecular biologist and bioinformatician studying the cell biology of human parasites. I have expertise in the bioinformatic analysis of parasite genomes to predict where proteins will reside in cell, how they participate in metabolic pathways, and how they might be suitable as targets for drugs and vaccines to control parasitic diseases.

We will investigate malaria, a parasitic disease that kills over 2 million people a year. We will explore how the parasite identifies, invades and remodels the host cells in which it lives, scavenging nutrients and hiding from the immune system. We will characterize the proteins involved in these critical events, as they are potential targets for drugs and vaccines. We will study how parasites cause disease and how the host responds to infection.

Functional Dissection Of The Malaria RhopH Complex And Its Contribution To New Permeation Pathways

Summary
The ability of Plasmodium to invade and remodel its host erythrocyte are the most significant contributors to its ability to cause the disease malaria. This project aims to understand how proteins secreted from a specialized rhoptry organelle during erythrocyte invasion help Plasmodium to remodel the erythrocyte so that the parasite can gain access to the vital nutrients it requires for survival. This research will validate whether drugs targeting the rhoptry proteins are viable drug targets.
Malaria is a devastating disease of global significance. With mounting resistance to current drugs and no licensed malaria vaccine, there is a pressing need to search for new strategies to reduce the global burden of malaria. My research program aims to understand how the parasites that cause malaria extensively renovate the cells in which they reside and subvert their host so that they can thrive and survive, with a view to identifying new pathways that can be targeted by drugs or vaccines.
Functional Characterisation Of The Malaria Protein Export Machinery

Summary
The ability of malaria parasites to cause one of the most devastating infectious diseases of humans is in part due to their ability to export hundreds of proteins into their host red blood cells to obtain nutrients, evade the immune system and contribute to associated pathologies. Recently, we discovered the molecular machine that exports proteins into the host cell and so now we wish to establish how it works so that drugs can be tailored to block it to kill these parasites.
Export Of PfEMP1, The Major Virulence Protein Of P. Falciparum, To The Parasite-infected Erythrocyte Surface

Summary
The malaria parasite infects red blood cells in the human host and initiates major remodelling. This involves export of a major virulence protein to the surface of the red blood cell. This research seeks to understand how the parasite exports this protein, a key determinant of disease.

Summary
Infection by the malaria parasite has lethal consequences for humans. In order to survive the parasite exports hundreds of proteins to commandeer the erythrocyte. A translocon that mediates such export has been identified and important questions remain unanswered. In this research, I aim to determine the function of one of the major translocon components for export of proteins to the erythrocyte (EXP2) and through this process determine if it is a viable target for anti-malarial drug development ....Infection by the malaria parasite has lethal consequences for humans.

Summary
Artemisinin-based antimalarials (ARTs) save hundreds of thousands of lives every year. Unfortunately resistance of P. falciparum to ART is now emerging in South East Asia and it is critical to know how and why. We will determine what is different about resistant parasites and will develop assays to monitor drug resistance in the field. We have found that the immature form of the malaria parasite is more resistant to ARTs, which helps explain resistance. We will build on this to develop new targe ....Artemisinin-based antimalarials (ARTs) save hundreds of thousands of lives every year.
