Summary
The control of several human pathogens depends on vaccine development due to antibiotic resistance and the devastating outcome of infection. This work aims to identify new vaccine targets for diseases including gonorrhoae, ear infections, meningitis and sepsis, based on proteins required for interaction with human cells. Proteins that are randomly switched on and off in these bacteria will also be studied to better understand disease and to rule out variably expressed genes from new vaccines.
Understanding And Modulating Hyperinflammation Caused By Influenza Viruses

Summary
In humans, highly pathogenic influenza A virus (IAV) infections can be fatal, as the disease is untreatable with available vaccine or anti-viral drugs. My fellowship aims to advance our knowledge of the mechanisms by which the immune system induces and regulates inflammation during IAV infection, which can be both helpful and detrimental in fighting the infection. This is critical for identifying and developing new therapies for severe IAV infections in the future.

Summary
Recurring infection in patients with fungal meningitis caused by Cryptococcus neoformans is typically caused by persistence of the original infection rather than reinfection with a new strain. Our analysis of relapse strains shows that small-scale alterations frequently occur at the chromosome ends - regions containing important pathogenesis-related genes in other pathogens. We seek to characterise this microevolution further to understand how it contributes to the success of this pathogen.
The Role Of Glycans In Arboviral Disease; From Immunomodulation To Glycotherapeutic Treatment Strategies

Summary
Dengue and chikungunya viruses are leading causes of emerging mosquito-transmitted (arboviral) disease worldwide. Currently there are no available vaccines or therapeutics making combatting these arboviral diseases one of our most pressing global health challenges. Preliminary evidence shows that glycan recognition is critical for disease immunopathogenesis. This project focuses on the role of viral glycans in arboviral disease with the aim of identifying and expanding on new therapeutic targets

We are currently experiencing unprecedented levels of antibiotic resistance in human pathogens. Unfortunately, the drug development pipeline is drying up, with almost no novel therapeutic options expected in the near future. This proposal aims to identify the mechanisms by which the most important antibiotic-resistant human pathogens make us sick. The expected outcomes are the identification of new targets that may be amenable to future drug development.

This proposal aims to identify the mechanisms by which the most important antibiotic-resistant human pathogens make us sick. The expected outcomes are the identification of new targets that may be amenable to future drug development. These targets are aimed at making the organisms less capable of causing disease in humans.Read moreRead less
The extraordinary virulence of malaria parasites is in part due to their ability to export hundreds of proteins into their host cell to obtain nutrients and avoid the immune system. Recently the investigator has discovered the machinery that provides the gateway for these proteins to enter the host cell. She now aims to characterise this machinery and dissect its functional significance in vivo, so that strategies that block this crucial process can be developed to kill the parasite.
