How bacteria cause disease in the urinary tract. This project will investigate the virulence properties of uropathogenic Escherichia coli, the major causative agent of urinary tract infections (UTI) in humans. The results will help to understand how these bacterial pathogens cause disease and will impact strategies aimed at the prevention and treatment of chronic and recurrent UTI.
New models as tools for defining mechanisms of microbe survival in the urogenital tract. Bacteria that infect the human urogenital tract can cause serious disease and these infections represent a large cost to the health-care system world-wide. This study will focus on how bacteria survive in the human urogenital tract and this will impact on strategies aimed at preventing and treating these infections.
DNA end resection: from basic mechanisms to genome editing. The project aims to understand processes underlying genome editing, a bioengineering process that introduces specific mutations into genomic DNA. Homologous recombination and nonhomologous end-joining pathways play a crucial role in repairing broken DNA strands, which are a toxic form of DNA damage. The proteins that function in the repair process have been recently identified, but it remains unclear how they function on a mechanistic l ....DNA end resection: from basic mechanisms to genome editing. The project aims to understand processes underlying genome editing, a bioengineering process that introduces specific mutations into genomic DNA. Homologous recombination and nonhomologous end-joining pathways play a crucial role in repairing broken DNA strands, which are a toxic form of DNA damage. The proteins that function in the repair process have been recently identified, but it remains unclear how they function on a mechanistic level and how either of the two main pathways is selected. The project aims to define how the activity of a key control protein, Sae2 (Sporulation in the Absence of Spo Eleven), is regulated by posttranslational modifications, and how this activates homologous recombination. The project plans to first use Saccharomyces cerevisiae yeast as a model and then to extend research into the human system in an attempt to improve the efficiency of genome editing.

Molecular and immunological approaches to managing Australia's seafood allergy epidemic. Seafood is an increasingly important cause of food allergy. Novel insight into the functions of why and how proteins from seafood develop to potent allergens will lead to the development of better diagnostics and therapeutics. This will assist patients to better manage their serious food allergy.
MOLECULAR APPROACHES TO OVERCOME SCABIES AND ASSOCIATED DISEASE. Scabies causes childhood pyoderma predisposing to severe disease in later life. It is a major increasing health burden in Indigenous people of Northern Australia. Drug resistance is developing in mites and bacteria. The lack of clinical material has hampered molecular research and this work will use comparative genomics of parasitic and free living mites and microbiome analysis to understand fundamental aspects of mite biology and ....MOLECULAR APPROACHES TO OVERCOME SCABIES AND ASSOCIATED DISEASE. Scabies causes childhood pyoderma predisposing to severe disease in later life. It is a major increasing health burden in Indigenous people of Northern Australia. Drug resistance is developing in mites and bacteria. The lack of clinical material has hampered molecular research and this work will use comparative genomics of parasitic and free living mites and microbiome analysis to understand fundamental aspects of mite biology and pathogenesis. The understanding of proteins that are essential for mite survival and interfere with host defences will allow the informed design of peptide inhibitors as a new strategy to develop alternative treatment options.Read moreRead less
Defining disease: Addressing the problem of overdiagnosis. This project will investigate and define the limits of physical disease, to answer questions about when a presentation is a disease, and when it is simply a risk factor or mild condition. The ensuing account of disease will make a practical contribution to growing international concern about asymptomatic people being diagnosed and treated for conditions that will not cause any health problems ("overdiagnosis"). The research will provide ....Defining disease: Addressing the problem of overdiagnosis. This project will investigate and define the limits of physical disease, to answer questions about when a presentation is a disease, and when it is simply a risk factor or mild condition. The ensuing account of disease will make a practical contribution to growing international concern about asymptomatic people being diagnosed and treated for conditions that will not cause any health problems ("overdiagnosis"). The research will provide normative grounds for evaluating disease claims. Results will reduce the harm caused by people receiving treatment that they do not require, make a practical contribution to debates about the scope of health care, and yield findings that can help to reduce the cost-burdens associated with overdiagnosis.Read moreRead less
Better end-of-life care through an optimal, holistic regulatory framework. This project aims to enhance end-of-life care through better regulation. Current regulation does not work as intended and is complex and fragmented. This harms patients, families and health professionals, and wastes health resources across the 100,000 medical end-of-life decisions in Australia annually. Expected outcomes are: (1) the first study internationally to establish in practice how the interaction of conflicting l ....Better end-of-life care through an optimal, holistic regulatory framework. This project aims to enhance end-of-life care through better regulation. Current regulation does not work as intended and is complex and fragmented. This harms patients, families and health professionals, and wastes health resources across the 100,000 medical end-of-life decisions in Australia annually. Expected outcomes are: (1) the first study internationally to establish in practice how the interaction of conflicting law, policies, ethics and training affects the end-of-life care patients receive; and (2) a new holistic regulatory framework to enhance the quality of end-of-life care. Expected benefits are better palliative care, more patient involvement in decisions, reduced patient-doctor conflict and a more efficient health system.Read moreRead less
Regulation of human immunodeficiency virus type 1 (HIV-1) replication by viral and cellular proteins. Using a mouse model, human cells will be treated with a very powerful antiviral protein using a gene therapy approach so as to block the human immunodeficiency virus (HIV) from growing. By learning how this antiviral protein works, this project will assist in the development of new strategies to treat HIV infection.
New drugs for malaria that target histone deacetylases. There is no vaccine for malaria and current drugs are failing, contributing to millions of malaria-related deaths each year. The aim of this project is to develop new drugs to address this significant global health issue. This project will focus on drugs that act in novel ways to existing malaria drugs by targeting enzymes that are involved in altering gene expression in the parasite. These kinds of enzymes are recognised drug targets in ot ....New drugs for malaria that target histone deacetylases. There is no vaccine for malaria and current drugs are failing, contributing to millions of malaria-related deaths each year. The aim of this project is to develop new drugs to address this significant global health issue. This project will focus on drugs that act in novel ways to existing malaria drugs by targeting enzymes that are involved in altering gene expression in the parasite. These kinds of enzymes are recognised drug targets in other diseases such as cancer. The outcomes of this project will include advances in malaria drug development that build on Australian drug discovery efforts, seeding further funding opportunities from industry and other sources and contributing research training and capacity building in Australia.Read moreRead less
Hybrid Imaging System for Breast Cancer Detection.
