This project aims to explore metabolic diversity of Klebsiella pneumoniae, a bacterium relevant to the agricultural, veterinary, medical and biotechnology industries. It is expected to reveal significant insights into the biology of this diverse organism via an innovative combination of DNA sequence analyses and metabolic modelling. Expected outcomes include 4500 novel metabolic models and a novel population metabolic framework. This should provide major benefits for understanding bacterial ecology and evolution, and for future studies seeking to optimise industrial processes or prevent disease. It will also directly contribute to building Australia’s capacity in computational biology- a key driver of biotechnology innovation.Read moreRead less
Using venoms to map critical and evolutionary conserved vulnerabilities. We have developed and applied new functional genomic approaches to study venom evolution. Using CRISPR screening, we find that unrelated venoms act on cells by exploiting the same vulnerabilities. By functionally mapping these vulnerabilities for all venom classes, we can begin to develop universal venom antidotes. Conversely, much of what we know about venom mechanisms comes from a small percentage of the biodiversity with ....Using venoms to map critical and evolutionary conserved vulnerabilities. We have developed and applied new functional genomic approaches to study venom evolution. Using CRISPR screening, we find that unrelated venoms act on cells by exploiting the same vulnerabilities. By functionally mapping these vulnerabilities for all venom classes, we can begin to develop universal venom antidotes. Conversely, much of what we know about venom mechanisms comes from a small percentage of the biodiversity within a venom, and we have developed genomic tools to study the venom “dark matter”. This work will lead to the full molecular characterisation of venom biodiversity, and new venom components will be useful for research or as novel medicines.Read moreRead less
Investigating the biogenesis and function of circular RNAs in the brain. Circular RNAs (circRNAs) are e a novel class of RNA molecules produced in a wide spectrum of eukaryotic organisms, from yeast to humans. Their expression is particularly high in the nervous system in the fruit fly, mouse and humans. What mechanisms are responsible for the tissue-specific enrichment of circular RNA expression? What are the consequences of circular RNA production on gene expression? The overall goal of the pr ....Investigating the biogenesis and function of circular RNAs in the brain. Circular RNAs (circRNAs) are e a novel class of RNA molecules produced in a wide spectrum of eukaryotic organisms, from yeast to humans. Their expression is particularly high in the nervous system in the fruit fly, mouse and humans. What mechanisms are responsible for the tissue-specific enrichment of circular RNA expression? What are the consequences of circular RNA production on gene expression? The overall goal of the proposed project is to elucidate these important aspects of circRNA biogenesis. Specifically, the project aims to (a) discover proteins that regulate circRNA expression, (b) elucidate how circRNA expression interacts with alternative splicing, and (c) identify circular RNAs that play regulatory roles in gene expression.

How does the noncoding genome regulate gene expression in the human brain? The non-coding genome is recognized as a major player in orchestrating gene expression in higher eukaryotes. This project aims to identify regions of the human genome that are important for gene expression during neuronal differentiation and depolarisation (i.e. neural enhancers), and to investigate their evolutionary properties. The roles of non-coding DNA in regulating the dynamic gene expression patterns underlying com ....How does the noncoding genome regulate gene expression in the human brain? The non-coding genome is recognized as a major player in orchestrating gene expression in higher eukaryotes. This project aims to identify regions of the human genome that are important for gene expression during neuronal differentiation and depolarisation (i.e. neural enhancers), and to investigate their evolutionary properties. The roles of non-coding DNA in regulating the dynamic gene expression patterns underlying complex human brain functions remains to be elucidated. By combining transcriptome quantification and bioinformatics methods, this project will close an important knowledge gap in our understanding of transcriptional regulation underlying human brain function. This will provide benefits such as the potential to influence public health policy including in cognitive functions and aging.Read moreRead less

Molecular systems biology of novel flower colour evolution. This project aims to discover new and potentially useful structural and regulatory genes while advancing knowledge of the chemical, genetic and ecological basis of unique evolutionary flower colour shifts. Dramatic shifts in floral colour is widespread in flowering plants, however, just how changes in flower colour occur remains poorly understood.

This project will take advantage of unique Australian plants to investigate the molecular mechanisms and evolutionary shift in flower colour changes. This project expects to advance knowledge on plant specialised metabolism with potential contributions to the floriculture, food and flavour industries.Read moreRead less
Formation of boundaries in the developing embryo. This project aims to decipher how the boundaries between the different organs are established in the developing embryo. The project aims to identify the components of the gene regulatory network that controls lateral plate mesoderm formation, develop a mathematical model that can explain how the domains are formed within this region, and validate novel interactions in vivo in zebrafish. The expected outcome of the project is to reveal how the pro ....Formation of boundaries in the developing embryo.

The project aims to identify the components of the gene regulatory network that controls lateral plate mesoderm formation, develop a mathematical model that can explain how the domains are formed within this region, and validate novel interactions in vivo in zebrafish. The expected outcome of the project is to reveal how the progenitors of our body parts are instructed to be positioned at the right time and at the right place in the embryo. This project should provide significant benefit such as the expansion of Australia's knowledge base and research capability in cross-disciplinary science.Read moreRead less

The project aims to develop high-resolution computational models for pandemic mitigation and control, focussing on the novel coronavirus and its emerging variants, and leveraging demographic, genomic and epidemiological data. It expects to rigorously compare multi-scale effects of complex vaccination and social distancing strategies and quantify optimal responses under the COVID-19 induced uncertainty.
