This project aims to generate new tools for vertebrate pest management through development of cutting-edge gene drive technology in mice. Vertebrate pests cost Australia over $1 billion each year in agricultural losses and environmental damage and novel strategies are required to tackle this challenge. Newly developed “gene drives”, which can rapidly spread through populations, have enormous potential for the sustained management and even eradication of pests. This project aims to develop gene drive technology in mice as a prototypical vertebrate pest species. The project will potentially deliver valuable tools that directly impact Australia’s Science and Research Priority on Food.Read moreRead less
Can parasites cause host population divergence? . Parasites have been proposed to be drivers of population divergence, and ultimately speciation, yet the dynamics of this process are not well understood. This project will utilise new genomic techniques, novel hybrid zone analyses, and data on mate choice, to investigate the hypothesis that parasites drive population divergence through an interaction with immune response genes in the sleepy lizard Tiliqua rugosa. This species provides an unpreced ....Can parasites cause host population divergence? . Parasites have been proposed to be drivers of population divergence, and ultimately speciation, yet the dynamics of this process are not well understood. This project will utilise new genomic techniques, novel hybrid zone analyses, and data on mate choice, to investigate the hypothesis that parasites drive population divergence through an interaction with immune response genes in the sleepy lizard Tiliqua rugosa. This species provides an unprecedented system, backed by 37 years of long term host-parasite and behavioural data, and recent genetic analyses. This project intends to produce significant data to allow an examination of the early stages of host-parasite evolution in action, providing novel insights into the speciation process.

The expected outcome of this ....Identification of Biological pathways regulated by circular RNAs. Circular RNAs (circRNAs) are a, recently discovered molecule. circRNAs are highly abundant and expressed in a tissue and disease specific manner. Yet, currently the understanding of how circRNAs regulate biological processes is very poor. This project aims to use pooled shRNA libraries to screen a large panel of cell lines and systematically identify cellular activities that are regulated by circRNAs. The expected outcome of this study will be a catalogue of functionally active circRNAs. Over the past decades, the wealth of knowledge on the function of linear mRNAs has had a significant impact on medicine and agriculture. Similarly understanding how circRNAs regulate cellular activities may have an analogous impact on humans.Read moreRead less

This project aims to investigate how healthy ageing impacts decision making and its associated neural circuits using computation modelling and neurogenetic methods. Decision-making is a fundamental cognitive ability, allowing us to choose the best course of action. This project will investigate the relationship between genes and decision-making performance across the adult lifespan. Expected outcomes include a deeper understanding of how decision-making evolves in healthy ageing, and a tool based on genetic scores and computational modelling to predict an individual's trajectory of cognitive function. This could help identify individuals who are at risk for cognitive decline, which could then inform better interventions.Read moreRead less

This project aims to further advance work on the genetic history of Indigenous Australians and Papuans that has revealed that Aboriginal Australians have inhabited a variety of diverse and challenging environments for approximately 50,000 years. Using novel techniques for extraction of human DNA from soil and the use of cutting-edge graph-based methods, hundreds of Indigenous Australian and Papuan genomes will be analysed. This project expects to generate new knowledge by filling in the gaps in the Australian genetic record via ancient human DNA from sediments. Expected outcomes from this project are producing a detailed picture of genomic adaptation in Indigenous Australians and Papuans and creating a comprehensive genetic history of the First Peoples of Sahul.Read moreRead less
Potential of gene drives to eliminate incursions of Drosophila suzukii. This project aims to test the efficacy and evolutionary stability of different types of gene drives, and model whether gene drives can be used to eliminate incursions of Drosophila suzukii into Australia.

This project aims to test the efficacy and evolutionary stability of different types of gene drives, and model whether gene drives can be used to eliminate incursions of Drosophila suzukii into Australia. It is now possible to use genome editing technology to alter populations of organisms using ‘gene drives’. Multiple strategies have been conceived with a major distinction between those that aim to eliminate populations versus those that aim to modify populations. This project will examine these strategies in two fly species, the model, Drosophila melanogaster and the devastating pest of horticulture, Drosophila suzukii. The project expects to assess a gene drive strategy to control the invasive pest that threatens the Australian soft-skinned fruit industries.Read moreRead less
