This project aims to characterise the variation in molecular evolutionary rates across the Tree of Life. Despite advances in genetic methods and genomic data, a critical gap remains in knowledge of evolutionary rates across species. The project will evaluate and refine methods for estimating rates, develop genomic data for molecular clocks, create an online database of rate estimates, and reconstruct ecological communities’ responses to past environmental and climatic factors. The project’s database of evolutionary rates in different species is expected to increase understanding of evolutionary and demographic events across species, including the Australian biota, and improve conservation efforts.Read moreRead less
The role of genome reorganisation in adaptation and speciation. Local adaptation and speciation are fundamental evolutionary processes that rely on changes to the genome. However, the role of genome architecture (e.g. chromosomal rearrangements, gene duplications) in driving these processes is poorly understood. This project will use advanced comparative genomics and bioinformatics to examine the role of chromosome rearrangements in driving adaptation and speciation, and evaluate rates of molec ....The role of genome reorganisation in adaptation and speciation. Local adaptation and speciation are fundamental evolutionary processes that rely on changes to the genome. However, the role of genome architecture (e.g. chromosomal rearrangements, gene duplications) in driving these processes is poorly understood. This project will use advanced comparative genomics and bioinformatics to examine the role of chromosome rearrangements in driving adaptation and speciation, and evaluate rates of molecular evolution between the X-chromosome and autosomes. Utilising Australia’s endemic mammalian fauna as a tractable model system, I will link population processes with macro-evolutionary outcomes to show how genome architecture underpins biodiversity.Read moreRead less
Animating the study of visual communication. This project aims to inform how dynamic colour signals broker information exchange by connecting stimulus design with perception through space and time. Biological studies of colour signalling have largely proceeded via static terms that underestimate the true fluidity of natural contexts.

This project aims to inform how dynamic colour signals broker information exchange by connecting stimulus design with perception through space and time. Biological studies of colour signalling have largely proceeded via static terms that underestimate the true fluidity of natural contexts. This project aspires to animate the field using innovative approaches such as programmable nano-drones to reveal how flashing colours are perceived under diverse viewing conditions. The knowledge advances are expected to generate new intellectual paradigms and models, and have significant scope for bio-inspiration in areas such as telecommunication, information processing and the optimal design of visual displays.Read moreRead less

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
Dissecting endocardial signals required for cardiac muscle regeneration in zebrafish. Unlike humans, zebrafish have an extraordinary ability to regenerate their damaged hearts. This project will study the endocardium, a thin layer of cells lining the inner heart, to find important genes for regeneration. Results from this study may provide insights into proper repair of human hearts after injury.
Understanding somatic mutation in plants: new methods, new software, new data. Somatic mutations accumulate as plants grow, affecting everything from short-term ecological interactions to long-term evolutionary dynamics. These mutations have important consequences for plant industry and conservation, but because they are so hard to measure almost nothing is known about them. This project aims to develop new methods and software to detect, analyse, and compare the genome-wide history of somatic m ....Understanding somatic mutation in plants: new methods, new software, new data. Somatic mutations accumulate as plants grow, affecting everything from short-term ecological interactions to long-term evolutionary dynamics. These mutations have important consequences for plant industry and conservation, but because they are so hard to measure almost nothing is known about them. This project aims to develop new methods and software to detect, analyse, and compare the genome-wide history of somatic mutation in individual plants, providing an unprecedented level of detail into an important but understudied source of biological variation. By applying these methods to an iconic experimental population, This project aims to provide the first insights into the genome-wide causes and consequences of somatic mutation in plants.Read moreRead less

Serous ovarian cancer is the most aggressive and lethal gynaecological cancer in Australian women. Activation of Mammalian Target of Rapamycin (mTOR) is frequently observed and associated with poor prognosis in ovarian cancer patients. However, the mechanisms dysregulating mTOR in the pathogenesis of ovarian cancer are unknown. In preliminary studies, deletion of genes regulating mTOR signalling in up to 60 per cent of human serous ovarian cancer patients was observed. This project will provide mechanistic details of involvement of mTOR signalling in pathogenesis of the serous ovarian carcinoma, and develop a rationale for targeting mTOR pathway in these patients.
