Summary
The bacterial associated oral diseases; periodontitis and caries are major public health problems. The prevalence of these diseases and increasing bacterial antibiotic resistance has meant there is a need to develop new therapies. This project addresses this by modifying a novel class of antibiotics/antiseptics �antimicrobial peptides� to target oral bacteria and testing them using a newly developed screening method. This project will lead to new therapies for periodontitis and caries.
Microstructural-Functional Effect of Silver Diammine Fluoride on Apatites. This project aims to develop a fundamental understanding at the nanostructural level of the factors that contribute to the enhanced mineralisation and mechanical properties of dentine and enamel following the treatment with silver diammine fluoride (SDF). A variety of advanced nanomechanical, tomographic and microscopic techniques will be used to characterise sound, carious and SDF treated tissue.

This project aims to develop a fundamental understanding at the nanostructural level of the factors that contribute to the enhanced mineralisation and mechanical properties of dentine and enamel following the treatment with silver diammine fluoride (SDF). A variety of advanced nanomechanical, tomographic and microscopic techniques will be used to characterise sound, carious and SDF treated tissue. The new biomechanical evidence on the underlying mechanisms, alternative protocols, delivery systems enable to optimise the treatment. The scientific insights into arresting/repairing damage processes will provide critical data for developing minimal intervention protocols for pediatric and geriatric populations.Read moreRead less

Identifying genes causing thermal evolution of ectotherm body size. Cold-blooded animals increase in body size as they are found in populations at greater distances from the equator. These patterns are due to populations adapting to temperature. The aim of this project is to identify the genes involved in this adaptation process. We will do this by taking advantage of a well-studied body size cline in the vinegar fly on the east coast of Australia, and by building on an international collaborati ....Identifying genes causing thermal evolution of ectotherm body size. Cold-blooded animals increase in body size as they are found in populations at greater distances from the equator. These patterns are due to populations adapting to temperature. The aim of this project is to identify the genes involved in this adaptation process. We will do this by taking advantage of a well-studied body size cline in the vinegar fly on the east coast of Australia, and by building on an international collaboration between a leading UK and two Australian research groups. In doing so we will provide an explanation at the molecular level for one of the great unresolved phenomena in biology: why do cold-blooded animals get bigger in the cold? The research also leads to the potential to manipulate body size in animals.Read moreRead less

Social Inequalities in Oral Health among Australian Working Age Adults. Australian working age adults with social and economic disadvantage have significantly poorer oral health outcomes than those from advantaged backgrounds. This project explores how changes in social position over time, and interactions between different forms of social disadvantage, contribute to social inequalities in oral health. This project expects to improve understanding of social inequalities in oral health, and its s ....Social Inequalities in Oral Health among Australian Working Age Adults. Australian working age adults with social and economic disadvantage have significantly poorer oral health outcomes than those from advantaged backgrounds. This project explores how changes in social position over time, and interactions between different forms of social disadvantage, contribute to social inequalities in oral health. This project expects to improve understanding of social inequalities in oral health, and its solutions, by developing and applying analytical and simulation models. This will help identify ways to reduce the persistent social inequalities in oral health outcomes in working age adults. In doing this, it will inform policies in future that will significantly improve the well-being of Australian working age adults.Read moreRead less
Population Health Planning For Rural Medicare Locals: Evaluating A Community Participation Method For Delivering Outcomes

Summary
The study, in six communities, will evaluate whether an evidenced based method of rural community participation from the UK translates to assist healthcare planning by Medicare Locals. Medicare Locals must involve local people in designing services to improve health, but lack methods to do this. The focus of the study is oral health, a major issue in rural areas. The study evaluates whether new services are designed and implemented and whether there is change to health knowledge and behaviours.

Genetic architecture and evolution of complex traits across populations. Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer. Using innovative statistical methods and largest genomic “big” datasets ever across populations of different ancestral backgrounds, this project expects to gen ....Genetic architecture and evolution of complex traits across populations. Most human traits have a genetic component and display substantial diversity within and among populations. How natural selection changes and maintains genetic variation in human traits is a long-standing question in evolution that the proposed project aims to answer. Using innovative statistical methods and largest genomic “big” datasets ever across populations of different ancestral backgrounds, this project expects to generate new knowledge on the roles of natural selection in shaping the genetic variation in traits and identify key factors that drive the differentiation of human populations. These outcomes will significantly improve our understanding on the evolution of human traits and adaptation of populations to changing environments.Read moreRead less
Why is most of the genetic variance for complex traits undetected by large powerful screens of common variants? The genomics revolution has made it possible to measure thousands of DNA variants in individuals. These variants have been associated with phenotypic outcomes in a range of species. Paradoxically, even very large studies have only accounted for a fraction of the resemblance between relatives that we know exist. Our study will test three specific hypotheses to explain this paradox. A be ....Why is most of the genetic variance for complex traits undetected by large powerful screens of common variants? The genomics revolution has made it possible to measure thousands of DNA variants in individuals. These variants have been associated with phenotypic outcomes in a range of species. Paradoxically, even very large studies have only accounted for a fraction of the resemblance between relatives that we know exist. Our study will test three specific hypotheses to explain this paradox. A better understanding about the genetic architecture for complex traits will improve the efficiency of gene mapping methods, including applications in humans for traits related to productive ageing and a healthy start to life, will lead to more efficient selection programs in agricultural populations and will inform us with respect to past evolutionary events.Read moreRead less
