Understanding evolution of dominant bacteria inhabiting the rodent gut . The gut microbiome is central to animal health and immune function, however we have an incomplete understanding of how this important symbiotic ecosystem evolved. By approaching this knowledge gap from a historical perspective and using real-time observation, this project will address how the gut community evolved with the rodent host and how members of that community respond to new selective pressures.

The gut microbiome is central to animal health and immune function, however we have an incomplete understanding of how this important symbiotic ecosystem evolved. By approaching this knowledge gap from a historical perspective and using real-time observation, this project will address how the gut community evolved with the rodent host and how members of that community respond to new selective pressures. The significance of these findings is in their capacity to inform our understanding of the relationship between host and microbe, not only within a key model system, but by extrapolation to other host-microbe systems.

Exploring the evolution and ecology of non-photosynthetic Cyanobacteria. This project aims to contribute and expand our rudimentary understanding of non-photosynthetic Cyanobacteria by obtaining representative genome sequences using metagenomics. The dogma that all Cyanobacteria are photosynthetic has recently been challenged by the discovery of non-photosynthetic lineages. This project expects to obtain representative genome sequences using metagenomics to predict surface structures.

Hyperactive endogenous retroviruses and their impact on the koala genome. Koala populations are in steep decline with the ubiquitous koala retrovirus (KoRV) strongly linked with disease. KoRV and other less studied endogenous retrovirus (ERVs) are extremely active within the genome of koalas to a level never observed in any other vertebrate genome. This study will map ERV integration sites within koalas from across their geographic range country and use long-read genomics approaches to understan ....Hyperactive endogenous retroviruses and their impact on the koala genome. Koala populations are in steep decline with the ubiquitous koala retrovirus (KoRV) strongly linked with disease. KoRV and other less studied endogenous retrovirus (ERVs) are extremely active within the genome of koalas to a level never observed in any other vertebrate genome. This study will map ERV integration sites within koalas from across their geographic range country and use long-read genomics approaches to understand the link between KoRV and other ERVs, the impact on koala caused by dramatic genomic rewiring, and the mechanisms of genomic immunity which supress ERV activity and mitigate disease. Findings will provide insights into the ongoing arms race between virus and host and inform conservation of an iconic species.Read moreRead less
Genomics and evolution of symbiont transmission in coral reefs. This project aims to understand more deeply the symbiosis between coral and the alga Symbiodinium that underpins the primary productivity, biodiversity and economic impacts of Australia's iconic Great Barrier Reef. Reef-building corals are sustained by symbiosis between the coral and the alga Symbiodinium, and breakdown of symbiosis under environmental stress leads to coral bleaching and death. This project aims to understand how ge ....Genomics and evolution of symbiont transmission in coral reefs. This project aims to understand more deeply the symbiosis between coral and the alga Symbiodinium that underpins the primary productivity, biodiversity and economic impacts of Australia's iconic Great Barrier Reef. Reef-building corals are sustained by symbiosis between the coral and the alga Symbiodinium, and breakdown of symbiosis under environmental stress leads to coral bleaching and death. This project aims to understand how genomes of differently acquired Symbiodinium have evolved to support symbiosis with corals, through sequencing of algal genomes of Symbiodinium. This knowledge will improve the precision in predicting change to inform decision-making strategies in the conservation and restoration of coral reefs.Read moreRead less
System-level characterisation of the siphonophore, Indo-Pacific man o' war. The Indo-Pacific man o' war (bluebottle), is a cnidarian from the siphonophore order. These animals frequent Australian beaches in swarms and cause thousands of stings every year. The project proposes to profile the genome, transcriptome, epigenome, and proteome of the bluebottle to gain insight into its life cycle, its behaviour, and toxins. Expected outcomes include the generation of novel information related to bluebo ....System-level characterisation of the siphonophore, Indo-Pacific man o' war. The Indo-Pacific man o' war (bluebottle), is a cnidarian from the siphonophore order. These animals frequent Australian beaches in swarms and cause thousands of stings every year. The project proposes to profile the genome, transcriptome, epigenome, and proteome of the bluebottle to gain insight into its life cycle, its behaviour, and toxins. Expected outcomes include the generation of novel information related to bluebottle gene regulation and its toxin repertoire, which will be highly beneficial for the design of future sting treatment strategies. Given that the bluebottle is a colony made of functionally specialised polyps, this study will also provide significant novel insight into the origins and evolution of animal multicellularity.Read moreRead less
The origins of Australia's non-Pama-Nyungan speaking people. This project aims to test the likelihood of multiple migrations into Australia before European arrival and determine if the phylogenetic relationships among non-Pama-Nyungan languages is mirrored by their speakers’ genomic phylogenetic relationships. The non-Pama-Nyungan First People of Australia speak an extraordinary number and diversity of Aboriginal languages, but the origins of these languages and the genomic diversity of the peop ....The origins of Australia's non-Pama-Nyungan speaking people. This project aims to test the likelihood of multiple migrations into Australia before European arrival and determine if the phylogenetic relationships among non-Pama-Nyungan languages is mirrored by their speakers’ genomic phylogenetic relationships. The non-Pama-Nyungan First People of Australia speak an extraordinary number and diversity of Aboriginal languages, but the origins of these languages and the genomic diversity of the people who speak them are only now starting to be understood. There is a remarkable concordance between the Pama-Nyungan languages and the genomic diversity of their speakers. This research could show whether genomes change languages or vice versa, or whether they evolve together over time.Read moreRead less

This project aims to characterise the evolutionary adaptations of a group of microorganisms with a key role in mitigating the release of methane into the atmosphere. Innovative molecular and visualisation-based approaches will be applied to uncover their metabolic diversity and evolutionary history. An important outcome of this study will be the comprehensive understanding of the contribution and impact these microorganisms have on the global carbon cycle, which will importantly inform accurate climate change models. This has clear benefits for society, given the precision of such models is essential in our ability to minimise the impact and associated cost of global warming.Read moreRead less
