Summary
I am a research scientist interested in the immune system. Specifically, I intend to investigate immunological memory, which is the basis of vaccination. This refers to the ability of certain immune cells such as T and B cells to ‘remember’ a pathogen, so that a rapid and enhanced response can be generated upon re-infection with the same pathogen. This can be investigated by experimental techniques such as flow cytometry, histology and confocal microscopy on cells from infected mouse tissue.
The Mechanisms Of SIV Entry Of Follicular Helper T Cells

Summary
Follicular helper T (Tfh) cells are a type of immune cells essential in antibody production. Preliminary data shows that SIV infects macaque Tfh cells. In this project, we will investigate the mechanisms by which SIV enters into Tfh cells, and test the susceptibility of human Tfh cells to HIV-1 infection ex vivo. This project will enable understanding of the fate of Tfh in HIV infection and its role in HIV host defense and it may facilitate the design of vaccine against HIV.
Mechanisms Of T Cell Mediated Injury In Renal Vasculitis

Summary
Anti-MPO glomerulonephritis (GN) is an aggressive disease causing severe and permanent injury to kidneys. This disease is thought to be due to an immune-mediated response to a protein (MPO) in neutrophils (a type of white blood cell). There is some evidence that other immune cells, CD4+ T cells, may be important in this disease. Experiments using models of anti-MPO GN will aim to define the role and mechanisms by which CD4+ T cells cause inflammation in the kidney.
Dengue Host-cell Signalling Interactions: Novel Insights And Interventions

Summary
Dengue is a virus transmitted by mosquitoes that occurs in many tropical and subtropical regions. Approximately 40% of the world's population is at risk of this infection. Sometimes it can be mild but it can lead to severe illness and death especially with second infections. The body produces a response that over-reacts to the virus in these severe infections. The project aims to understand why the body does this and what parts of the immune system are affected using a model in mice.
Investigating The Role Of Mucosal Associated Invariant T (MAIT) Cells In Mycobacterium Tuberculosis

Summary
Tuberculosis (TB) is a deadly infectious disease that kills 2 million people per year worldwide. If we are to eliminate this disease, we urgently need a new TB vaccine. I plan to look at what role a newly discovered type of T cell might play in TB infection and to see whether these cells can be manipulated by vaccination. This work will help us to understand more about the body’s first response to TB infection and how we can use this response in the design of new TB vaccines.
Antigen-specific Regulatory T Cells And HLA Associations In Autoimmune Renal Disease

Summary
Glomerulonephritis (GN), a common cause of kidney failure, usually results from an immune system attack on the kidneys. Current treatments suppress the whole immune system, making patients vulnerable to infection. We aim to harness the body’s protective immune cells (Tregs) as a potential GN treatment. Using mice genetically programmed to mimic a human GN, we will test if specifically targeted Tregs protect mice from disease. We will also test how they affect blood samples from humans with GN.
Determining The Mechanisms Of Tolerance After Autologous Stem Cell Transplantation For Multiple Sclerosis – The Role Of CD39+ T Regulatory Cells

Summary
Autologous haematopoietic stem cell transplant offers relief for patients with aggressive forms of autoimmune diseases such as multiple sclerosis. Here, we aim to understand how this therapy relieves symptoms in multiple sclerosis patients by studying the biology of CD39+ T regulatory cells. Understanding these immune-suppressing cells can lead to the development of new transplant procedures without chemotherapy and ultimately improve transplant outcomes for autoimmune disease patients.
Understanding Influenza-specific T Cell Immunity In The Indigenous And Non-Indigenous Populations

Summary
Hospitalisation and mortality rates from influenza are high in the Indigenous population. There is an urgent need for one-shot universal vaccine that protects against seasonal and pandemic strains. To identify potential vaccine targets we firstly have to determine which viral proteins will induce a large protective immune response. These responses vary between ethnicities thus comparisons will be drawn between Indigenous and non-Indigenous Australians to determine multiple vaccine candidates tha ....Hospitalisation and mortality rates from influenza are high in the Indigenous population.

Accelerated Longterm Forgetting In Children With Genetic Generalised Epilepsy: An Investigation Of The Temporal Trajectory And Contribution Of Executive Skills.

Summary
The aim of this study is to determine which factors influence forgetting in typically developing children and in children with epilepsy. Specifically, we want to establish how forgetting occurs over time and whether it is influenced by other cognitive/thinking skills, such as strategies used to remember information, attention or resistance to interference. Moreover, we are interested in whether retention rates are affected by different types of learning materials (i.e. visual versus verbal).

Summary
The appendix has been regarded as a useless organ, however, there are evidence showing its removal reduces the risk of developing inflammatory bowel disease. We have shown that this may be due to altered intestinal immune regulation. The project plans to explore the mechanisms responsible for this altered immune regulation. With knowledge of specific elements of disease causation gained from these studies, more effective and targeted treatment options will become available.
