Maintaining fidelity in viral Ribonucleic acid (RNA) polymerases. This project will provide informed insights into the dynamics of viruses that currently impact a healthy start to life, ageing well and productively, and preventative healthcare. The analysis of viruses that cause gastroenteritis outbreaks will increase our understanding of how these viruses replicate and spread.
Mechanisms of human immunodeficiency virus entry into cells. This project will develop an understanding of how human immunodeficiency virus (HIV) evolves in people to become better able to infect, and hence destroy, cells of the immune system. It is expected that new knowledge into how HIV alters the way it interacts with these cells will reveal insights for the design of vaccines, drugs and new diagnostic tests.
Bio-engineering Insect-Specific Flaviviruses for control of arboviruses. This project aims to study a family of commensal viruses of mosquitoes called insect-specific flaviviruses that are naturally found in mosquitoes and do not infect or cause disease in vertebrate hosts. Using an innovative approach, this project employs cutting-edge molecular virology approaches to modify these insect-specific flaviviruses to enhance their ability to block the replication of other pathogenic viruses in the m ....Bio-engineering Insect-Specific Flaviviruses for control of arboviruses. This project aims to study a family of commensal viruses of mosquitoes called insect-specific flaviviruses that are naturally found in mosquitoes and do not infect or cause disease in vertebrate hosts. Using an innovative approach, this project employs cutting-edge molecular virology approaches to modify these insect-specific flaviviruses to enhance their ability to block the replication of other pathogenic viruses in the mosquito vector. Expected outcome of this project is a bio-control strategy that is complementary to the Wolbachia approach. The anticipated benefits include the advancement of knowledge of insect-specific flaviviruses, and promotion of interdisciplinary research across the fields of Entomology and Virology.Read moreRead less
A single vaccine for influenza and pneumonia. Influenza and bacterial pneumonia collaborate to kill millions of people each year. This project aims to develop a single vaccine that will provide long-lasting protection against both influenza and pneumonia.
The cellular basis of sex-specific responses to virus infection. This project aims to explore how the sex of cells impacts virus infections in culture. To date, the sex of cells in culture has been overlooked as an important source of biological variability, but may be found to affect basic science through to anti-viral drug discovery. Using a model in which a virus can be adapted to grow better in cells of a single sex, this project expects to generate new knowledge about how sex differences im ....The cellular basis of sex-specific responses to virus infection. This project aims to explore how the sex of cells impacts virus infections in culture. To date, the sex of cells in culture has been overlooked as an important source of biological variability, but may be found to affect basic science through to anti-viral drug discovery. Using a model in which a virus can be adapted to grow better in cells of a single sex, this project expects to generate new knowledge about how sex differences impact virus-host interactions. This project expects to provide new insights into sex-based differences in how cells detect and respond to virus infection, and the extent to which the sex of cells impacts viruses in general.Read moreRead less
Virus and host genes and the outcome of infection. Viruses cause infection of all animals including people and the outcome of infection is highly variable. This project aims to use genetics to explain why some animals are more susceptible to particular virus infections and some strains of virus cause more severe diseases. The project will also explore whether all cells are similarly susceptible to killing by viruses.
The ins and outs of HIV biology. This project aims to delineate the fundamental mechanisms that regulate the production of HIV and the ability of HIV to cause AIDS in infected patients. It will utilise state-of-the-art technologies to unearth new clues that govern the biology of HIV, with the ultimate goal to develop novel vaccine and treatment strategies against HIV.

Summary
Identification and characterisation of anti-viral immune response genes in mosquitoes. Emerging viral diseases, transmitted by mosquito bite, present an increasing public health risk globally. Most research to date has neglected the infection dynamic in the insect vector. This project aims to characterise the defensive response of mosquitoes to viral infection, a potentially crucial factor in the epidemiology of vector-borne disease.
Linking immunomodulation and latency in alphaherpesvirus infection. Herpesviruses cause major diseases in humans and all domestic animal species. Latency forms a significant part of the evolutionary success of herpesviruses, by enabling transmission of the virus throughout the lifetime of the host. Our work has shown that an alphaherpesvirus protein can divert the host’s immune response to become more antibody-mediated and less T cell-mediated. This study explores the consequences of this immune ....Linking immunomodulation and latency in alphaherpesvirus infection. Herpesviruses cause major diseases in humans and all domestic animal species. Latency forms a significant part of the evolutionary success of herpesviruses, by enabling transmission of the virus throughout the lifetime of the host. Our work has shown that an alphaherpesvirus protein can divert the host’s immune response to become more antibody-mediated and less T cell-mediated. This study explores the consequences of this immune diversion, and examines whether this reduced T cell response enables the development of latent infections. Disrupting the virus-host balance by alterations to this conserved viral protein will enable novel approaches to controlling these economically significant viruses.Read moreRead less
Seeking causes of unexplained respiratory illness in children by identifying new respiratory viruses. Many respiratory illnesses including the common cold, ear infections, asthma attacks, the flu and pneumonia have no known cause even after all specimen testing is complete. This project will use 'virus hunting' experience to find and sequence as-yet-undiscovered viruses from such specimens so that they can be studied in more detail.
