Unravelling the principles of bilateral brain wiring. This project seeks to investigate the molecular principles of brain wiring in mammals and how small changes can generate complex outcomes. Neurons in the mammalian brain must be precisely wired together for the brain to function correctly. The project aims to identify the molecular and cellular rules governing commissural wiring in the mammalian cortex to determine how the largest fibre tract in the human brain, the corpus callosum, evolved. ....Unravelling the principles of bilateral brain wiring. This project seeks to investigate the molecular principles of brain wiring in mammals and how small changes can generate complex outcomes. Neurons in the mammalian brain must be precisely wired together for the brain to function correctly. The project aims to identify the molecular and cellular rules governing commissural wiring in the mammalian cortex to determine how the largest fibre tract in the human brain, the corpus callosum, evolved. This may have involved modifications in mechanisms affecting axon guidance that differ between placentals and marsupials. The project investigates the regulatory gene networks determining commissural neuron fate, the regulation of axon guidance components, and the influence of surrounding brain tissue on the development of commissural connections.Read moreRead less
Unravelling reef fish vision through gene-editing and behavioural ecology. This project aims to enhance understanding of visual neuroscience, genetic control of vision and environmental ecology on The Great Barrier Reef (GBR). Using the anemonefish as a model, together with new genetic, photographic and behavioural approaches, the project aims to reveal novel aspects of colour vision on the reef. Outcomes beyond multiple scientific disciplines include enhanced international collaboration and bui ....Unravelling reef fish vision through gene-editing and behavioural ecology. This project aims to enhance understanding of visual neuroscience, genetic control of vision and environmental ecology on The Great Barrier Reef (GBR). Using the anemonefish as a model, together with new genetic, photographic and behavioural approaches, the project aims to reveal novel aspects of colour vision on the reef. Outcomes beyond multiple scientific disciplines include enhanced international collaboration and building capacity for improved reef guardianship. The benefits are scientific discovery in multiple areas, providing greater community understanding of complex science and a desire to preserve the GBR for future generations.Read moreRead less
Molecular control of postnatal heart development. This project aims to improve our understanding of how the heart develops after birth and the molecules that control this process. Recent advances in tissue engineering have opened up opportunities for the generation of synthetic tissues but these studies have also highlighted a fundamental knowledge gap in our understanding of how complex tissues mature to prepare for life as an adult. Much is known about the molecules that control early embryoni ....Molecular control of postnatal heart development. This project aims to improve our understanding of how the heart develops after birth and the molecules that control this process. Recent advances in tissue engineering have opened up opportunities for the generation of synthetic tissues but these studies have also highlighted a fundamental knowledge gap in our understanding of how complex tissues mature to prepare for life as an adult. Much is known about the molecules that control early embryonic development but little is known about the molecules that control maturation after birth. This project aims to build new knowledge that is expected to improve our ability to generate mature heart muscle cells for stem cell applications, tissue repair and regeneration.Read moreRead less
Is SPINT1 a key regulator of placental development? . The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion o ....Is SPINT1 a key regulator of placental development? . The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion of the placental exchange interface which is critical for offspring survival.
The project will increase understanding of placental development, enhance collaboration and research knowhow, and promote future applied projects in all species that reproduce via placental support.Read moreRead less
Using Drosophila to analyse a master regulator of epithelial homeostasis. Aims:
This proposal aims to use genetic and cell biological analysis of the vinegar fly, Drosophila, to identify the function of the grainyhead gene in intestinal regeneration.
Significance:
This gene is conserved in all animal species and appears to be a master regulator of epithelial tissue development but it is unclear how it can both influence stem cell maintenance and production of functional cell types.
Expected out ....Using Drosophila to analyse a master regulator of epithelial homeostasis. Aims:

Significance:
This gene is conserved in all animal species and appears to be a master regulator of epithelial tissue development but it is unclear how it can both influence stem cell maintenance and production of functional cell types.
Expected outcomes:
We will identify a new mechanism that governs tissue development, and introduce new imaging and genetic technologies to the Australian research community.
Benefit:
We expect potential economic and commercial interest in development of new gene analysis tools and biotechnological tissue manipulation applications.Read moreRead less
Defining signals that regulate intestinal stem cells during organ growth. This project will define the key signals that promote cell division in the stem cells which produce the inner epithelial lining of the gut. This fundamental knowledge is of significance as it will provide information about how key signals are delivered to promote repair of injury to this key cell layer. The gut is a vital organ conserved across species that is prone to injury as it is exposed to a very harsh environment of ....Defining signals that regulate intestinal stem cells during organ growth. This project will define the key signals that promote cell division in the stem cells which produce the inner epithelial lining of the gut. This fundamental knowledge is of significance as it will provide information about how key signals are delivered to promote repair of injury to this key cell layer. The gut is a vital organ conserved across species that is prone to injury as it is exposed to a very harsh environment of bacteria and the products of food digestion. The outcomes of this project will provide an understanding of development and regeneration of the epithelial lining and key signals that may augment repair. The future benefits include improved health outcomes for animals and humans and potential economic benefits.Read moreRead less
