The Origin and Evolution of the Animal Phyla inferred from Analysis of Multiple-Gene Data. Australia has recently begun an extensive research programme in the genomics of our flora and fauna. The enormous amounts of data that emerge from such research are highly complex, but they hold the key to understanding how biological organisms change over time. Our research will untangle that data to answer fundamental, unanswered questions in modern science: How did the animal groups originate?

Australia has recently begun an extensive research programme in the genomics of our flora and fauna. The enormous amounts of data that emerge from such research are highly complex, but they hold the key to understanding how biological organisms change over time. Our research will untangle that data to answer fundamental, unanswered questions in modern science: How did the animal groups originate? How are they related to each other? How is biodiversity changing? The answers to these questions and the new analytical tools we will develop will put Australia firmly on the international "map" of Bioinformatics.Read moreRead less
Analysing and modelling molecular rate variation among nuclear and mitochondrial genomes. My research will have important practical benefits for bioinformaticians and evolutionary biologists, because existing analytical methods will be rigorously tested and new tools will be developed. Australia has a comparatively high concentration of researchers in this field, so my research will foster domestic collaboration and import international expertise. The research will provide important insights int ....Analysing and modelling molecular rate variation among nuclear and mitochondrial genomes. My research will have important practical benefits for bioinformaticians and evolutionary biologists, because existing analytical methods will be rigorously tested and new tools will be developed. Australia has a comparatively high concentration of researchers in this field, so my research will foster domestic collaboration and import international expertise. The research will provide important insights into the rates and patterns of genetic changes associated with domestication, and into variation in evolutionary rates among the primate ancestors of humans. In addition to developing new software, which will be made publicly available, I will develop new evolutionary models to supplement existing software packages. Read moreRead less
Improving the accuracy of phylogenetic reconstruction by improving models of sequence divergence. Phylogenies describe the relationships among species and provide the essential framework for understanding evolutionary processes. They are an essential tool in the identification of functionally important regions in DNA sequences. An important aspect of identifying phylogenies is measuring how DNA sequences change in time. The proposed research will develop sophisticated, practical models of sequen ....Improving the accuracy of phylogenetic reconstruction by improving models of sequence divergence. Phylogenies describe the relationships among species and provide the essential framework for understanding evolutionary processes. They are an essential tool in the identification of functionally important regions in DNA sequences. An important aspect of identifying phylogenies is measuring how DNA sequences change in time. The proposed research will develop sophisticated, practical models of sequence divergence and make them freely available in open source software. The software and models will positively impact on studies seeking to understand Australian biological diversity. The proposed resolution of the eutherian mammal orders will further significantly impact on utilisation of rodents as a model organism for human biology.Read moreRead less

Increasingly, large Australian multicentre research programs in biological and medical sciences have a genomics component that involves integration of biological information with sequencing data. The success of these research programs depends on rapid internet access to the research information by all participating scientists. The universal design of the proposed information management system means that it can be easily adapted to support a broad range of research programs. The development of this software program therefore has the potential to benefit research scientists, academics and students in many related fields, as well as the broader community, through enhancing research outcomes.Read moreRead less
How does ecological disturbance shape the genetic diversity of natural populations? Environmental disturbances shape the dynamics of the world's ecosystems. However, we do not understand how they influence biodiversity at its most fundamental level, genetic diversity. This is important, because genetic diversity affects the fitness of individuals, the viability of populations and the adaptability of species. This project will study fire in the Australian environment to discover how disturbance a ....How does ecological disturbance shape the genetic diversity of natural populations? Environmental disturbances shape the dynamics of the world's ecosystems. However, we do not understand how they influence biodiversity at its most fundamental level, genetic diversity. This is important, because genetic diversity affects the fitness of individuals, the viability of populations and the adaptability of species. This project will study fire in the Australian environment to discover how disturbance affects genetic diversity. By integrating landscape genomics and computational modelling with long-term field studies, the research will significantly advance our understanding of how genetic diversity is distributed, and improve our ability to predict the responses of natural populations to changes in the frequency and severity of wildfire.Read moreRead less

Beyond genes: How the extended genotype of plants facilitates adaptation. Adaptation to environmental change is required for species to persist, however rapid environmental change may exceed the limits of traditional genetic adaptation leading to widespread decline. Recent work has highlighted the 'extended genotype' as an additional factor influencing adaptive phenotypes. This project aims to examine DNA methylation and polyploidisation as both a cause and consequence of the adaptation process ....Beyond genes: How the extended genotype of plants facilitates adaptation. Adaptation to environmental change is required for species to persist, however rapid environmental change may exceed the limits of traditional genetic adaptation leading to widespread decline. Recent work has highlighted the 'extended genotype' as an additional factor influencing adaptive phenotypes. This project aims to examine DNA methylation and polyploidisation as both a cause and consequence of the adaptation process using natural populations of the model cereal Brachypodium distachyon. The project aims to determine the architecture of these features and how their variability impacts adaptive traits such as flowering time. From the functional role of the extended genotype the project endeavours to predict and select genetic responses to the environment.Read moreRead less
