Making muscle: molecular dissection of membrane domain formation. For a muscle to contract efficiently in response to an electrical signal it requires the formation of an extensive system of hollow membranous tubules through which the signal can be propagated. This proposal addresses the molecular mechanisms involved in the formation of this tubule system in skeletal muscle. This project will develop cell biology in a whole organism rather than a cell culture system and provide a new framework f ....Making muscle: molecular dissection of membrane domain formation. For a muscle to contract efficiently in response to an electrical signal it requires the formation of an extensive system of hollow membranous tubules through which the signal can be propagated. This proposal addresses the molecular mechanisms involved in the formation of this tubule system in skeletal muscle. This project will develop cell biology in a whole organism rather than a cell culture system and provide a new framework for Australian and international cell biologists. It will generate new knowledge, train young Australian scientists, help build international collaborative networks and engage the public outside the research community.Read moreRead less
Algal direct-air CO2 capture through interfacial enzyme immobilisation . Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs. By understanding mass transfer an ....Algal direct-air CO2 capture through interfacial enzyme immobilisation . Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs. By understanding mass transfer and enzyme activity in the interfacial immobilisation media, floating enzyme rafts can be developed for deployment over expansive areas, facilitating large-scale conversion of atmospheric CO2 into algae-derived fuels, feeds and chemicals.Read moreRead less
New biocatalysts for selective chemical oxidations under extreme conditions. This project will identify and design new enzyme biocatalysts which function under extreme conditions such as elevated temperature and high concentrations of peroxides. These enzymes will be sourced from microorganisms which are located in extreme biological environments e.g. hot springs (the so-called extremophiles). The expected outcome of this project are the identification of robust enzymes which can catalyse select ....New biocatalysts for selective chemical oxidations under extreme conditions. This project will identify and design new enzyme biocatalysts which function under extreme conditions such as elevated temperature and high concentrations of peroxides. These enzymes will be sourced from microorganisms which are located in extreme biological environments e.g. hot springs (the so-called extremophiles). The expected outcome of this project are the identification of robust enzymes which can catalyse selective oxidation reactions in complex organic molecules, such as steroids. The new biocatalysts developed in this project will have significant benefit in the development of new routes to access bespoke molecules of value in fine chemical synthesis and drug development.

Understanding crosstalks between Natural Killer cells and Dendritic Cells. This project aims to investigate the interactions between two populations of immune cells: natural killer cells and dendritic cells. This proposal will advance basic knowledge in immunology by innovating in considering the heterogeneity and diversity of these two immune populations and combining interdisciplinary approaches using cutting-edge technologies. Expected outcomes from this proposal include the identification of ....Understanding crosstalks between Natural Killer cells and Dendritic Cells.

This project aims to develop robust protein cages derived from the coats of viruses to contain heat-stable P450 enzymes, for use as specialised protein bio-catalysts in chemical industries. A valuable chemical precursor of renewable bio-plastics will be produced from seed oils by enzymes, reducing the use of fossil fuels. This synthetic biology approach combines biotechnology, nanotechnology and protein engineering to establish a plant-based platform biotechnology for using enzymes as catalysts to make high-value molecules. The project aims to show how to engineer clean, sustainable chemistry in designer nano-environments. This should make synthetic processes more sustainable and enhance advanced chemical manufacturing in Australia.Read moreRead less

ARC Centre of Excellence in Quantum Biotechnology. The ARC Centre of Excellence in Quantum Biotechnology aims to develop paradigm-shifting quantum technologies to observe biological processes and transform our understanding of life. It seeks to create technologies that go far beyond what is possible today, from portable brain imagers to super-fast single protein sensors, and to use them to unravel key problems including how enzymes catalyse reactions and how higher brain function emerges from networks of neurons. By building a diverse, multidisciplinary, and industry-engaged ecosystem, the Centre means to develop our future leaders at the interface of quantum science and biology and drive Australian innovation across manufacturing, energy, agriculture, health, and national security.Read moreRead less
Click chemistry to reveal how neurons and glia shape perineuronal nets . The extracellular matrix (ECM) and its perineuronal nets (which are net-like structures with holes wrapped around neurons) are largely underexplored, despite representing a remarkable 20% of the brain’s total volume and having been suggested to be involved in many brain functions. Interestingly, digestion of the ECM improves learning and memory, but deficits return once the ECM has reformed. However, how this ECM remodellin ....Click chemistry to reveal how neurons and glia shape perineuronal nets . The extracellular matrix (ECM) and its perineuronal nets (which are net-like structures with holes wrapped around neurons) are largely underexplored, despite representing a remarkable 20% of the brain’s total volume and having been suggested to be involved in many brain functions. Interestingly, digestion of the ECM improves learning and memory, but deficits return once the ECM has reformed. However, how this ECM remodelling is organised at a cell-type level is not understood. Here we aim to close this knowledge gap, using cutting-edge technology including bioconjugation and ultrasound-mediated cargo delivery. Together, this project aims to contribute to a deeper understanding of this major brain compartment in neuronal function. Read moreRead less

Arteries and veins display different adhesive properties, which enable them to fulfil their physiological roles. We are yet to understand the mechanisms that establish and maintain adhesive function in different vessel types. We have discovered that signalling by the peptide Adrenomedullin (ADM) is a key mediator of adhesion, only in veins but not arteries. This project aims to utilise innovative models (zebrafish, mouse and bioengineered vessels) to identify the biochemical and mechanical mechanisms by which ADM controls venous adhesion. Outcomes will improve our understanding on how vessel integrity is controlled across vessel types and will expand the scope of Australian research by informing efforts to vascularise engineered tissues.Read moreRead less
