Understanding diet designs that break life history trade-offs. The aim of this project is to understand the mechanisms by which organisms use nutrition to enhance fitness. Food availability is a key predictor of evolutionary fitness. Surprisingly, recent data shows that some key assumptions informing how these predictions are realised are not strictly correct, thus exposing a lack of important mechanistic knowledge. This project seeks to understand these mechanisms. The project plans to use nove ....Understanding diet designs that break life history trade-offs. The aim of this project is to understand the mechanisms by which organisms use nutrition to enhance fitness. Food availability is a key predictor of evolutionary fitness. Surprisingly, recent data shows that some key assumptions informing how these predictions are realised are not strictly correct, thus exposing a lack of important mechanistic knowledge. This project seeks to understand these mechanisms. The project plans to use novel genomics techniques to develop diets that support or improve fitness under circumstances such as stress or ageing, and to understand the molecular underpinnings of these improvements. Project outcomes may expand academic knowledge of fundamental nutritional biochemistry, and improve predictions of species’ responses to environmental change.Read moreRead less
The birth and death of mammalian sex chromosomes. This project aims to unravel the molecular mechanisms that underlie the transition from autosome to sex chromosome and progressive sex chromosome differentiation in mammals. Monotremes are the only mammalian species with a sex chromosome system that consists of ten sex chromosomes in platypus and nine in echidna. This project will analyse the genetic and epigenetic composition and organisation of the monotreme autosomes that evolved into sex chro ....The birth and death of mammalian sex chromosomes. This project aims to unravel the molecular mechanisms that underlie the transition from autosome to sex chromosome and progressive sex chromosome differentiation in mammals. Monotremes are the only mammalian species with a sex chromosome system that consists of ten sex chromosomes in platypus and nine in echidna. This project will analyse the genetic and epigenetic composition and organisation of the monotreme autosomes that evolved into sex chromosomes in other mammals and compare individual platypus and echidna sex chromosomes to discover how sex chromosomes come to be, differentiate and ultimately are replaced by new sex chromosomes.Read moreRead less
Discovering sex determining genes in a reptile with genetic and environmental sex determination. Reptile sex determination is particularly fascinating because it is triggered either by genes on sex chromosomes or by the nest temperature. This project will identify and characterise candidate sex determining genes in a model reptile to understand how genes control sexual differentiation and how they interact with temperature.
Using ‘omic and digital technologies toward better fasciolosis control. In Australia, liver fluke disease caused by Fasciola hepatica causes major economic losses to livestock production. Triclabendazole is the most effective drug for parasite control, however, resistance to this drug has emerged and continues to spread in Australia. This project expects to create a novel resource to identify new drug targets, generate new knowledge about the genetic composition of F. hepatica populations and un ....Using ‘omic and digital technologies toward better fasciolosis control. In Australia, liver fluke disease caused by Fasciola hepatica causes major economic losses to livestock production. Triclabendazole is the most effective drug for parasite control, however, resistance to this drug has emerged and continues to spread in Australia. This project expects to create a novel resource to identify new drug targets, generate new knowledge about the genetic composition of F. hepatica populations and unravel the genetic determinants underlying triclabendazole resistance. The curation of functionally-annotated genetic data for F. hepatica populations will underpin the development of diagnostic tests, drugs and vaccines to deliver a new generation of intervention strategies to control liver fluke disease.Read moreRead less
Resolving insect evolution. Our poor understanding of the evolution of insects, life’s most successful group, is a huge gap in our knowledge of nature. By analysing genomic data the project will resolve the insect evolutionary tree and discover what drove insect evolution. This will expand our knowledge of how evolution works - a vital part of conserving our biological diversity.
Development of population-level algorithms for modelling genomic variation and its impact on cellular function in animals and plants. The purpose of this project is to develop mathematical and computational tools which will enable researchers to model high-throughput biological data at the population level. These models will be used to uncover the effect that genetic variation has on the physiology of the cell and the organism.
The adaptive evolution of key methane-utilising microorganisms. 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.

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
Uncovering new microbial players and processes in the global methane cycle. This project aims to utilise multiple analytical strategies (including metagenomics and metatranscriptomics) to substantially expand our understanding of the key microorganisms, metabolic strategies, and interspecies relationships involved in the formation and consumption of methane. The global methane cycle is controlled by microorganisms that produce and consume this important greenhouse gas, however it is now recognis ....Uncovering new microbial players and processes in the global methane cycle. This project aims to utilise multiple analytical strategies (including metagenomics and metatranscriptomics) to substantially expand our understanding of the key microorganisms, metabolic strategies, and interspecies relationships involved in the formation and consumption of methane. The global methane cycle is controlled by microorganisms that produce and consume this important greenhouse gas, however it is now recognised that there are many as-yet undiscovered methane-metabolising microorganisms in the environment. The project will lead to a greater understanding of the contribution of these novel microorganisms to global carbon cycling and their links to climate change. This will directly benefit modelling efforts to understand future climate change scenarios.Read moreRead less
Coral-associated viruses: pathogens, mutualists and agents of evolution? Corals host numerous organisms, of which viruses are the least studied. The aim of this project is to characterise the viruses associated with corals and to obtain a detailed understanding of the critical roles that viruses play in coral health, coral bleaching and adaptation of corals to climate change.
Defining pathways that establish and maintain reproductive cell identity in plant ovules and seeds. Unlike animals, individual somatic cells in plants have the remarkable ability to regenerate into new plants, depending on the signals they perceive. This developmental plasticity is particularly important during normal plant growth, when mature cells adopt new identities within multicellular environments. Tissue complexity is critical for the utilisation of plants in society as food, fuel and fib ....Defining pathways that establish and maintain reproductive cell identity in plant ovules and seeds. Unlike animals, individual somatic cells in plants have the remarkable ability to regenerate into new plants, depending on the signals they perceive. This developmental plasticity is particularly important during normal plant growth, when mature cells adopt new identities within multicellular environments. Tissue complexity is critical for the utilisation of plants in society as food, fuel and fibre, but how and why plant cells adopt or change identity has been difficult to determine. This project aims to employ next-generation molecular methods to identify pathways driving differentiation of specific ovule and seed cell-types, which directly impact crop quality, yield and end-use.Read moreRead less
