A Method for Analysis of Complexity in Cognitive Processes: Applications to Prediction of Industrial Workloads. The project will develop a method for analysis of cognitive complexity in human and animal cognition. It will contribute to basic research because it will enable equivalences and relative complexities of cognitive functions to be determined, independent of content or methodology. It will have applications to education, because it enables complexities of concepts to be recognised and a ....A Method for Analysis of Complexity in Cognitive Processes: Applications to Prediction of Industrial Workloads. The project will develop a method for analysis of cognitive complexity in human and animal cognition. It will contribute to basic research because it will enable equivalences and relative complexities of cognitive functions to be determined, independent of content or methodology. It will have applications to education, because it enables complexities of concepts to be recognised and appropriate pedagogies determined. It also has application to human factors, especially industrial performance and decision making. It will advance on currrent methods because it enables workload to be analysed and predicted, so that it can be factored into job and system design. Read moreRead less
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. T ....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. 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.

Storage of Volatiles in the Mantle Lithosphere: Time-scales, sources and processes. Fragments of the Earth's mantle (xenoliths), transported to surface by deep-seated volcanics, record the injection of fluids through formation of volatile-bearing minerals (mantle metasomatism). This project will 1) test the hypothesis that timescales of mantle volatile storage can be determined using noble gas (laser probe) dating techniques, and 2) determine the sources and processes involved in volatile stor ....Storage of Volatiles in the Mantle Lithosphere: Time-scales, sources and processes. Fragments of the Earth's mantle (xenoliths), transported to surface by deep-seated volcanics, record the injection of fluids through formation of volatile-bearing minerals (mantle metasomatism). This project will 1) test the hypothesis that timescales of mantle volatile storage can be determined using noble gas (laser probe) dating techniques, and 2) determine the sources and processes involved in volatile storage, using halogen and noble gas geochemistry. A successful outcome will establish unique methods for dating mantle metasomatic events and determine the relationship between mantle and crust melting episodes, thus providing critical constraints on mantle evolution and Earth degassing models.

Understanding the dynamics of the dark universe. This project aims to test theories of dark matter and dark energy with the ultimate goal of understanding the properties of the dark components of the universe and how those properties can be explained by new fundamental physics. The project will use two astronomical datasets, the Dark Energy Survey, with measurements of approximately 3000 supernovae, and the Dark Energy Spectroscopic Instrument, with measurements of 30 million galaxies. By compar ....Understanding the dynamics of the dark universe. This project aims to test theories of dark matter and dark energy with the ultimate goal of understanding the properties of the dark components of the universe and how those properties can be explained by new fundamental physics. The project will use two astronomical datasets, the Dark Energy Survey, with measurements of approximately 3000 supernovae, and the Dark Energy Spectroscopic Instrument, with measurements of 30 million galaxies. By comparing theoretical models to this combination of data the project will help to determine whether dark energy changes with time, measure detailed clustering properties of dark matter, and test advanced theories of gravity.Read moreRead less
Theoretical Foundations of Ethical Machine Learning. The project aims to develop a systematic theory of ethical machine learning. Machine learning is a powerful and pervasive technology that is already having a huge impact on Australia. When applied to data about people there are a range of ethical harms that can arise (fairness, and privacy are two of them). The project aims to develop a rigorously grounded foundation for managing such ethical harms. For example it will allow the quantification ....Theoretical Foundations of Ethical Machine Learning. The project aims to develop a systematic theory of ethical machine learning. Machine learning is a powerful and pervasive technology that is already having a huge impact on Australia. When applied to data about people there are a range of ethical harms that can arise (fairness, and privacy are two of them). The project aims to develop a rigorously grounded foundation for managing such ethical harms. For example it will allow the quantification of the inevitable trade-offs between fairness and utility. The benefits of the project should include better ways of managing these trade-offs, a competitive advantage for Australian firms developing the technology, and will ensure that the country retains a social license to use the technology.Read moreRead less
Investigating Wnt signaling during human nephron commitment and patterning. Aims: To use gene edited stem cell lines that display cell location, identity and cell state to map human kidney tissue formation in the laboratory. By monitoring how each cell responds to those around it across time and space, we will for the first time map the formation of kidney tissue in the dish.
Significance: Understanding how stem cells form a tissue will help us to improve and control the process. This is key to ....Investigating Wnt signaling during human nephron commitment and patterning.

Significance: Understanding how stem cells form a tissue will help us to improve and control the process. This is key to advancing tissue engineering.
Expected outcomes: The proposal will pioneer state-of-the-art imaging, gene editing and machine learning approaches, generating models of human development that are currently unavailable.
Benefits: This understanding will guide the development of novel approaches to tissue engineering.

The discovery of biologically active molecules, in particular drug discovery, requires the design and synthesis of host molecules that bind selectively to the biological target. Combinatorial chemistry has greatly assisted this discovery process as it allows the rapid screening of large collections of molecules. In this proposal, metal ion interactions will be used in the combinatorial library as this will greatly increases the diversity of the pool of compounds to be screened for activity. Understanding how to generate and analyze these libraries has potential applications in drug screening, the discovery of new substrates, enzymes and inhibitors. Read moreRead less

This project will produce environmental records during ocean warming events in the geologic past to reveal processes associated with warm oceans similar to those anticipated in the coming century. New Australian technology allows investigation of sediment records at unprecedented time resolution providing insight into processes operating on societally relevant time scales of decades to centuries. This work will open an archive of climate information revealing feedback, thresholds and tipping points from past events previously inaccessible because of technical and conceptual limitations. It will provide critical inputs into models predicting future climate and to illuminate the risks and compensating feedbacks occurring with warming.
