Research on iconic Australian mammals has profoundly reshaped our understanding of reproductive biology and sex chromosome evolution. In this project we combine unique expertise, international collaboration and novel genetic information about Australia's unique egg-laying mammals (echidna and platypus) to investigate major aspects of reproduction. This work will address fundamental aspects of sex chromosome biology and advance our understanding of mammalian reproduction. The knowledge gained will have application in captive breeding and conservation of these extraordinary Australian mammals. The project also provides opportunity to train research students in cutting edge molecular biology and informatics.Read moreRead less
Complex trait analyses based on genome-wide approaches. This project aims to develop whole genome approaches that can improve the estimation and prediction power by using information from the dynamic genetic architecture of complex traits (i.e. the changes of genetic characteristics and effects when varying effective population size and genetic backgrounds). The project intends to deliver advanced statistical models, efficient algorithms and design by combining data from close relatives, populat ....Complex trait analyses based on genome-wide approaches. This project aims to develop whole genome approaches that can improve the estimation and prediction power by using information from the dynamic genetic architecture of complex traits (i.e. the changes of genetic characteristics and effects when varying effective population size and genetic backgrounds). The project intends to deliver advanced statistical models, efficient algorithms and design by combining data from close relatives, population samples or from different populations (e.g. multi-ethnicities or multi-breeds). The expected outcome is to better understand the dynamic architecture of complex traits and develop methods with improved power, precision and accuracy in genomic analyses.Read moreRead less
Epigenetics, environment, and evolution. This project will aim to understand how biological information can exist and be passed from one generation to the next without being encoded in the gene sequence, and also how our early environment can modify this so-called "epigenetic" information to alter disease risk.
Beyond the genome: unravelling the intricacies of epigenetic regulation using the honey bee model. Epigenetic mechanisms, such as DNA methylation, provide the interface between genome and environment. Abnormalities in epigenetic regulation lead to cancer and other diseases. The project will be using the alternative phenotypes in honeybees, fertile queens and sterile workers, to understand how dietary factors control conditional gene expression by methylation
Defining unconscious and artificial selection. In 1868 Charles Darwin proposed that the process of domestication can be divided into two independent selective processes we now call unconscious and artificial selection. In this project, we include the Australian dingo as a functional intermediate between the wild wolf and domestic dogs and test Darwin's hypothesis using modern molecular and statistical techniques. It is now widely accepted that the dingo was not domesticated by indigenous Austral ....Defining unconscious and artificial selection. In 1868 Charles Darwin proposed that the process of domestication can be divided into two independent selective processes we now call unconscious and artificial selection. In this project, we include the Australian dingo as a functional intermediate between the wild wolf and domestic dogs and test Darwin's hypothesis using modern molecular and statistical techniques. It is now widely accepted that the dingo was not domesticated by indigenous Australians and is therefore the ideal extant population for the project. The project is significant because it will be a critical test of Darwin's hypothesis. The outcome could be an improved understanding of the genomic basis for selection that can inform the process of domestication.Read moreRead less

Summary
The inheritance of epigenetic information in mammals. This project aims to understand how biological information can be passed from one generation to the next without being encoded in the genes. This may explain questions as diverse as why twins look subtly different and why some families are more likely than others to suffer disease.
From the pouch to the grave: age and sex related changes in immunity in the Tasmanian devil. Tasmanian devils face extinction in the wild due to the emergence of a contagious cancer: Devil Facial Tumour Disease (DFTD). A comprehensive understanding of the devil immune system is necessary to better understand the disease and develop a vaccine against it. This project will characterise immune responses of healthy devils throughout life, from the pouch, to onset of puberty, to old age. This project ....From the pouch to the grave: age and sex related changes in immunity in the Tasmanian devil. Tasmanian devils face extinction in the wild due to the emergence of a contagious cancer: Devil Facial Tumour Disease (DFTD). A comprehensive understanding of the devil immune system is necessary to better understand the disease and develop a vaccine against it. This project will characterise immune responses of healthy devils throughout life, from the pouch, to onset of puberty, to old age. This project will then compare these responses in DFTD-affected devils to determine why DFTD affects older animals first and does not affect sexually-immature devils. Additional outcomes will include the development of novel antibiotics against human and animal diseases and an atlas of devil development using the latest imaging technologies.Read moreRead less
Rerunning the evolution of an ancient bacterial propeller. This project aims to measure how the propeller which drives bacterial swimming originated and then evolved. This project expects to generate new knowledge in molecular evolution using interdisciplinary techniques in synthetic biology and biophysics to resurrect ancient proteins and test how they can be directed to evolve in a contemporary host. Expected outcomes include the development of new types of flagellar motor for applied uses in ....Rerunning the evolution of an ancient bacterial propeller. This project aims to measure how the propeller which drives bacterial swimming originated and then evolved. This project expects to generate new knowledge in molecular evolution using interdisciplinary techniques in synthetic biology and biophysics to resurrect ancient proteins and test how they can be directed to evolve in a contemporary host. Expected outcomes include the development of new types of flagellar motor for applied uses in synbio and microfluidics, and new methods to resurrect ancient proteins and evolve their function for purpose. This should provide significant benefits by delivering a de novo molecular motor for custom applications and galvanise public interest in how this iconic molecular complex originated and evolved.Read moreRead less
Epigenetic inheritance: how does it work? This project aims to determine the mechanisms responsible for the inheritance of acquired traits. Sometimes the environment can have effects on the phenotype of not only the exposed individual, but also their children and grandchildren. While it is clear that this can occur, what is not clear is the mechanism by which this happens and the frequency at which it happens. This project will use the model organism Caenorhabditis elegans, innovative new techni ....Epigenetic inheritance: how does it work? This project aims to determine the mechanisms responsible for the inheritance of acquired traits. Sometimes the environment can have effects on the phenotype of not only the exposed individual, but also their children and grandchildren. While it is clear that this can occur, what is not clear is the mechanism by which this happens and the frequency at which it happens. This project will use the model organism Caenorhabditis elegans, innovative new techniques for the discovery of low abundance RNA molecules, and fluorescence microscopy to analyse structures within the cell nucleus to determine what the molecular mechanism is by which this "transgenerational epigenetic inheritance" occurs. This will have an impact on evolutionary theory, as well as long-term consequences for the understanding of human health and disease, and the impact of a changing climate on agriculture.Read moreRead less
