Speech perception precedes, indexes, and is changed by language acquisition. What is exceptional about human infants is not their sophisticated speech perception (for animals perceive human speech similarly) but their use of speech to regulate linguistic attention and bootstrap language. Using a new validated measure, language specific speech perception (discrimination ability for native minus non-native speech sounds), we can ascertain children's distribution of resources in linguistic tasks.

What is exceptional about human infants is not their sophisticated speech perception (for animals perceive human speech similarly) but their use of speech to regulate linguistic attention and bootstrap language. Using a new validated measure, language specific speech perception (discrimination ability for native minus non-native speech sounds), we can ascertain children's distribution of resources in linguistic tasks. This measure will be used in conjunction with a raft of experimental psycholinguistic techniques to investigate speech perception bases of phoneme perception, tone perception, word meaning, reading, and their vestiges in adulthood, to arrive at a dynamic new conception of language development.

Summary
How do neural circuits coordinate to produce adaptive changes in behaviour? This project aims to discover how neurons alter their function in coordinated ways to produce adaptive changes in behaviour. Behavioural outputs result from the activity of multiple cells in a functional network, but current methods are limited to studying signalling effects on single neurons. To address this, I will develop new methods to visualise every cell in the brain of the living nematode worm to provide a unique ....How do neural circuits coordinate to produce adaptive changes in behaviour? This project aims to discover how neurons alter their function in coordinated ways to produce adaptive changes in behaviour. Behavioural outputs result from the activity of multiple cells in a functional network, but current methods are limited to studying signalling effects on single neurons. To address this, I will develop new methods to visualise every cell in the brain of the living nematode worm to provide a unique systems-level understanding of a model brain. Through collaboration with engineers and psychologists, I will describe molecular switches that trigger reorganisation of entire neural networks. Expected outcomes include new insights on neural circuit plasticity, which will advance discovery in neuroscience and robotics.Read moreRead less

Should I stay or should I go? How brain stem cells leave quiescence. Most adult stem cells in our brains are sleeping (quiescent). Quiescence helps ensure animals have a lifelong population of brain stem cells, which is crucial for the maintenance of brain circuitry.

How brain stem cells leave quiescence. Most adult stem cells in our brains are sleeping (quiescent). Quiescence helps ensure animals have a lifelong population of brain stem cells, which is crucial for the maintenance of brain circuitry. This project aims to investigate how this process is regulated at a molecular level. This project expects to define the molecular playbook controlling quiescence and explain why brain stem cells progress into deeper states of quiescence during aging by combining novel tissue culture and genetic models, where brain stem cells have disrupted quiescence, with innovative methods of reading gene expression. The benefits of these outcomes include the development of methods to control the quiescence of brain stem cells for bioengineering purposes.Read moreRead less
Synthetic genes as reference standards for biology and biomanufacture. Reference standards are needed to improve the measurement of biology and the reliability of biomanufacturing processes. This project aims to engineer synthetic genes capable of acting as reference standards for DNA, RNA and protein. The synthetic genes can be transcribed into mRNA standards, and translated into protein standards, and be further integrated into living cells to measure internal cellular processes.
The outcomes ....Synthetic genes as reference standards for biology and biomanufacture.

This project aims to engineer synthetic genes capable of acting as reference standards for DNA, RNA and protein. The synthetic genes can be transcribed into mRNA standards, and translated into protein standards, and be further integrated into living cells to measure internal cellular processes.
The outcomes include a unified understanding of gene expression and more accurate next-generation sequencing and mass-spectrophotometry technologies. The synthetic genes also allow standardisation and optimisation of biomanufacturing processes that will produce mRNA and biologics products at a higher purity and lower cost.Read moreRead less
A fast comparative method for historical linguistics. Linguists are able to infer ancient histories of languages by a procedure known as the Comparative Method. Its results are used in related studies of human genetic and cultural change. However, the Comparative Method is a manual-only process and thus currently is a bottleneck for the science of unravelling the human past. This project aims to overcome this limitation and significantly accelerate linguistic discovery, by combining recent advan ....A fast comparative method for historical linguistics. Linguists are able to infer ancient histories of languages by a procedure known as the Comparative Method. Its results are used in related studies of human genetic and cultural change. However, the Comparative Method is a manual-only process and thus currently is a bottleneck for the science of unravelling the human past. This project aims to overcome this limitation and significantly accelerate linguistic discovery, by combining recent advances in computational language processing, statistics and cultural-evolutionary modelling. By producing innovative mathematical means for rapidly discovering ancient language relationships, it will enable a breakthrough in our capacity to uncover human linguistic, genetic and cultural heritage worldwide.Read moreRead less

This project aims to determine how the quantity and nature of screen time interacts with parental co-participation to affect pre-schoolers’ social skills and cognitive functioning. Seventy per cent of pre-schoolers exceed current screen time guidelines and this causes considerable concern among Australian parents. This project will assist in evaluating how much, and which types, of screen time have benefits for social skills and cognitive functioning. It will also provide insights into the ways parents may best support these outcomes. Findings are expected to provide evidence for policy development and inform programs to support healthy behaviours to give young children the best start in life.Read moreRead less

This project will investigate a novel paradigm of how a key messenger protein can be sensed by fundamental immune cells, preventing their ‘exhaustion’. Immune cell exhaustion is a fundamental mechanism to maintain the internal homeostasis of vertebrates. However, it is often hijacked by pathogens to dampen the defensive capacity of the immune system. And this specific messenger protein is the only known soluble factor that can deliver ‘anti-exhaustion’ signals to immune cells. This study will advance basic knowledge in biochemistry and immunology by combining interdisciplinary and cutting-edge approaches. The expected outcomes include the developing new scientific theories and identifying novel molecular basis of biological processes. Read moreRead less

This project seeks to determine how protein interactions with membrane lipids regulate recruitment to cellular organelles, providing new insight into the complex pathways of cellular homeostasis. Controlling the distribution of proteins within cells is critical for cell signalling and membrane trafficking. This is orchestrated by the interaction of specific protein modules with lipids on the surface of different organelles. The phox homology (PX) domain is a lipid-binding module found in numerous proteins essential for normal cell trafficking and homeostasis, and perturbed in many conditions including immune dysfunction and cancer. This project plans to investigate molecular determinants of PX-lipid association, generating knowledge about protein-membrane interactions required for cellular function. These insights may underpin future drug design.Read moreRead less

This is important because these predictions are commonly used to guide environmental decisions, but the standard modelling methods used to produce them have critical limitations. This project intends to (i) make key statistical developments to methods for modelling dynamics of species distributions and (ii) translate the methods into practice, through guidelines, tools and training, engagement with users and case studies addressing species of current concern. This should provide significant benefits because it will enable better decisions and more effective and cost-efficient management actions.Read moreRead less
