Directed evolution of ancestral bacterial flagellar motors. This project aims to produce new knowledge concerning the adaptation of bacterial species to wide environmental changes. The bacterial flagellar motor (BFM) is a motor 40 nanometers in diameter that builds itself into bacterial membranes, rotates five times faster than a Formula One engine, and switches directions in milliseconds. . This project will combine ancestral reconstruction of ancient motor components with protein engineering t ....Directed evolution of ancestral bacterial flagellar motors. This project aims to produce new knowledge concerning the adaptation of bacterial species to wide environmental changes. The bacterial flagellar motor (BFM) is a motor 40 nanometers in diameter that builds itself into bacterial membranes, rotates five times faster than a Formula One engine, and switches directions in milliseconds. . This project will combine ancestral reconstruction of ancient motor components with protein engineering to understand how the different ion channels that power the BFM in different species are selective for different positive ions. It will inspire and inform future manufacturing in bionanotechnology.Read moreRead less
The molecular basis of oligotrophy: an integrated genomic and functional proteomic study of the model marine oligotroph, Sphingopyxis alaskensis. The project will will enable Australia to take the lead in the global analysis of oligotrophy, highlighting the reputation Australian scientists have in scientific programs of global significance. As Australia is surrounded by some of the most oligotrophic waters in the world, we have access to an enormous natural resource suitable for the isolation of ....The molecular basis of oligotrophy: an integrated genomic and functional proteomic study of the model marine oligotroph, Sphingopyxis alaskensis. The project will will enable Australia to take the lead in the global analysis of oligotrophy, highlighting the reputation Australian scientists have in scientific programs of global significance. As Australia is surrounded by some of the most oligotrophic waters in the world, we have access to an enormous natural resource suitable for the isolation of oligotrophs. Realising the potential of oligotrophs may therefore provide an invaluable source of compounds, enzymes and molecules for biotechnology and industry. Understanding microbial oligotrophy will also ensure we protect our $50 billion dollar tourism industry by remaining abreast of factors which influence the marine environment and directly impact on all coastal activities.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
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
Whole-genome multivariate reaction norm model for complex traits. This project aims to develop a multivariate whole-genome genotype-covariate correlation and interaction model that can be applied to a wide range of existing genome-wide association study (GWAS) datasets. Genotype-covariate correlation and interaction (GCCI) are fundamental in biology but there is no standard approach to disentangle interaction from correlation in the whole-genome analyses. This project will address the key featur ....Whole-genome multivariate reaction norm model for complex traits. This project aims to develop a multivariate whole-genome genotype-covariate correlation and interaction model that can be applied to a wide range of existing genome-wide association study (GWAS) datasets. Genotype-covariate correlation and interaction (GCCI) are fundamental in biology but there is no standard approach to disentangle interaction from correlation in the whole-genome analyses. This project will address the key feature in biology, which relates to dissecting the complex mechanism of association and interaction. The proposed statistical model implemented in a context of a novel design based on multiple GWAS data sets is a paradigm shifting-tool with applications to multiple industries.Read moreRead less

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).

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
