Summary
Chronic pain is common, with one in five Australians having long-term pain that is serious enough to cause disability. Unfortunately this type of pain is difficult to treat, and current medicines are ineffective in many people, with unwanted side-effects. The aim of this project is to understand how signalling in the spinal cord changes following the development of chronic pain so we can find better strategies to reverse the symptoms and treat pain more effectively.

Summary
Understanding and harnessing the fundamental cellular process of secretion will provide a wealth of new approaches to addressing problems associated with aging & disorders that are major health care burdens (e.g. neurodegeneration & diabetes). Understanding the vesicle docked state, and the contributions of different molecular components to the release process provides for unique insights into the underlying molecular mechanisms, thereby enabling safe, targeted control of this critical process.
I am a cell biologist who studies the molecular mechanisms that couple cells together into tissues in the body. These adhesion mechanisms are essential during development, support normal tissue turnover and are disrupted in human disease. My research aims to understand how cell adhesion functions normally and how it is disturbed in inflammation and cancer.

Summary
Diarrhoea resulting from infection with Shigella and Escherichia coli is a major cause of sickness and death in the developing world, especially in children. Even in Australia, these bacteria, which may be food borne, are occasionally responsible for life threatening infections. In this study, we will investigate the contribution to diarrhoeal disease of large fragments of foreign DNA which have been recently acquired by these bacteria.

Even in Australia, these bacteria, which may be food borne, are occasionally responsible for life threatening infections. In this study, we will investigate the contribution to diarrhoeal disease of large fragments of foreign DNA which have been recently acquired by these bacteria. We will characterise several of these elements in detail, identifying novel virulence determinants and toxins in the process. We will also explore the means by which these packages of nasty DNA transfer between bacteria and investigate their potential to give rise to new, more virulent strains of bacteria. This study is particularly significant because it will lead to an improved understanding of how bacteria cause disease and may help to guide us in developing better strategies for the prevention of bacterial diarrhoea. Specifically, the work done on characterising large clusters of virulence genes will allow us to construct safer bacterial vaccines and we expect that in the future this knowledge will contribute to the development of new and better diagnostic and therapeutic agents against these harmful bacteria.Read moreRead less

Malaria is a serious disease that affects half of the world's population and frequently kills humans after a bout of high fever and coma. Many of those who die are young children who live in areas of the world where health care is very poor. The effectiveness of drugs that we currently have available to prevent or treat malaria is rapidly reducing and there is no vaccine available to prevent people from catching the disease.

Many of those who die are young children who live in areas of the world where health care is very poor. The effectiveness of drugs that we currently have available to prevent or treat malaria is rapidly reducing and there is no vaccine available to prevent people from catching the disease. Our research is important because in order to make better medicines for malaria we have to get to know more about how the malaria parasite makes people sick. The most vicious form of malaria is caused by a tiny parasite called Plasmodium falciparum that lives inside the red blood cells in our bodies. As these minute parasites grow, they make a lot of major changes to the red blood cells and as a result they become very stiff and sticky. This is very bad for the infected person because instead of flowing around the body like normal red blood cells, the infected cells become trapped in small veins and can no longer do their normal job. The ability of the parasite to redecorate red blood cells and make them stiff and sticky is what makes this type of malaria so dangerous, particularly when red cells get stuck in the brain. The research that we will do here will help us to understand the ways in which the malaria parasite sends out these sticky substances to the walls of red blood cells. Eventually, this will help us to find ways to stop the red blood cells from becoming sticky and prevent so many people from becoming very sick and dying with malaria.Read moreRead less
