I am an immunologist determining how the immune system is regulated, with the aim of preventing diseases such as asthma, type 1 diabetes and multiple sclerosis caused by dysregulated immune responses.
The immune system plays an important role in protecting the host from viral and bacterial infections, and inhibits cancer onset and progression. Unfortunately the immune system can sometimes lose specificity and attack the host resulting in autoimmune diseases such as diabetes. This research team has played a vital role in characterising the specific activities of immune cells and the associated factors.

Unfortunately the immune system can sometimes lose specificity and attack the host resulting in autoimmune diseases such as diabetes. This research team has played a vital role in characterising the specific activities of immune cells and the associated factors. By understanding these complex processes the team aims to harness the unique therapeutic properties of our own immune system and translate their findings into the clinic.Read moreRead less

Summary
Multiphoton microscopy of living animals as a tool for immunology and cell biology studies. The multiphoton microscope will enable us to watch the growth, migration and interactions of cells in a living animal in response to changes in the cells' environment will give us better understanding of how we work as living machines, and what can go wrong with that process to make us unwell.
The Structural Basis Of T Cell Recognition In The Context Of Lipid Presentation And The CD1 Isoforms

Summary
CD1 molecules are critical in our host-defence against microbial pathogens. They survey our body for microbial lipids and then present them to our immune system for surveillance by T cell receptors. We aim to understand how a T cell receptor interacts with a CD1-lipid molecule. This interaction is crucial to the activation of our immune response and hence the elimination of the microbe. Once understood, this interaction can potentially be modified and has immunotherapeutic potential.
Improving and manipulating the immune adjuvant properties of recombinant fowlpox vectors. Unbalanced immune responses may cause or worsen common and important diseases such as infections, allergies, cancers and autoimmunity. Interleukin-4 (IL-4) is the only immune active product or cytokine that safely skews an aberrant immune response to a healing type of response.

Unbalanced immune responses may cause or worsen common and important diseases such as infections, allergies, cancers and autoimmunity. Interleukin-4 (IL-4) is the only immune active product or cytokine that safely skews an aberrant immune response to a healing type of response. Fowlpox viruses (FPV) provide safe and effective human vaccines. Engineering FPV to make both a relevant antigen and a cytokine is proprietary technology. With our commercial partner and using experimental mice, we will test the concept that FPV making a model antigen and IL-4 initiate and/or maintain beneficial Type 2 responses. A successful outcome will guide clinical FPV-based vaccine development for the treatment of important human and veterinary diseases.Read moreRead less
Inflammatory processes are normally regarded as being initiated and maintained through the activities of white blood cell macrophages. We propose to explore the role of lymphocyte delivery of protease molecules termed granzymes in inflammation. Our preliminary data has demonstrated a novel paradigm involving amplification of septic shock through the activity of granzymes. We now wish to exlore these interactions at a cellular and biochemical level as a means to better understand inflammation.

Immunotherapy is a potentially powerful and specific form of cancer therapy that may be more effective and have fewer side effects than current forms of therapy including chemotherapy and radiotherapy. Already dramatic responses have been observed in a proportion of patients receiving immunotherapy for some malignancies but these responses are all too infrequent.

Already dramatic responses have been observed in a proportion of patients receiving immunotherapy for some malignancies but these responses are all too infrequent. T cells constitute an important part of the immune system but they often fail to recognize cancer and do not respond strongly enough against tumours. This project investigates the feasibility of endowing patients' T cells with the abilities to recognize cancer and respond vigorously against it by genetically modifying the T cells. In this study, T cells are removed from mice that have cancer and a gene encoding an anti-cancer molecule inserted into the T cells. The T cells are activated, grown to large numbers and given back to tumour-bearing mice followed by booster vaccinations. The strategy used is novel and the proposed studies, together with preliminary data, represent the first investigations of their type in the world. Information derived from these studies will extend our understanding of tumour immunology and provide an appreciation of the importance of various parameters in achieving anti-tumour responses. Improved anti-tumour responses achieved through investigations in these proof-of-principle pre-clinical models could lead to more effective immunotherapeutic regimens in patients.Read moreRead less
New technology for the delivery of peptide-based T-cell vaccines for tumour immunotherapy. This project is dedicated to finding simple methods for vaccinating humans and animals against a wide variety of cancers. Should this be achieved millions of Australians will be protected from the devastating consequences of cancer. Consequently there will be great benefits socially, medically and economically.
