Species redundancy in response to multiple disturbances. This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances. Studies that merely observe biodiversity change after disturbance cannot identify ecological processes connecting high diversity and e ....Species redundancy in response to multiple disturbances. This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances. Studies that merely observe biodiversity change after disturbance cannot identify ecological processes connecting high diversity and ecosystem function, making experiments that manipulate identical disturbances in ecosystems with different biodiversity essential. This project will use field experiments that manipulate disturbances in streams replicated in low and high biodiversity regions and across gradients of chronic background stress to show how biodiversity sustains functional ecosystems, and how much diversity can be lost before ecosystems collapse.Read moreRead less
Quantifying and parameterising ocean mixing. This project aims to advance our ability to describe the efficiency and intensity of ocean mixing. The project will develop and apply innovative techniques to estimate ocean mixing from both traditional ship-based, vertical-profiling turbulence measurements and from autonomous moorings. The project will undertake a re-analysis of historic measurements and obtain new measurements using autonomous systems. The results will be used to develop both a uni ....Quantifying and parameterising ocean mixing. This project aims to advance our ability to describe the efficiency and intensity of ocean mixing. The project will develop and apply innovative techniques to estimate ocean mixing from both traditional ship-based, vertical-profiling turbulence measurements and from autonomous moorings. The project will undertake a re-analysis of historic measurements and obtain new measurements using autonomous systems. The results will be used to develop both a universal relationship describing the efficiency of ocean mixing, and to quantify the underlying length scale controlling mixing intensity. This will enable the development of the next generation of turbulence closure models needed to describe ocean circulation and stirring.Read moreRead less
Enhancing gravitational wave detector sensitivity and bandwidth for astronomy. This project aims to create small optomechanical devices that amplify the signals in gravitational wave detectors, increasing their sensitivity, especially for higher frequency signals. Calibrated against the 2015 first detection of gravitational waves from black hole mergers, this technology could allow humanity to listen to black holes merging up to 30 times every day, while giving much greater sensitivity to signal ....Enhancing gravitational wave detector sensitivity and bandwidth for astronomy. This project aims to create small optomechanical devices that amplify the signals in gravitational wave detectors, increasing their sensitivity, especially for higher frequency signals. Calibrated against the 2015 first detection of gravitational waves from black hole mergers, this technology could allow humanity to listen to black holes merging up to 30 times every day, while giving much greater sensitivity to signals from smaller black holes and neutron stars. The new technology, which uses nano-scale suspended tiny mirrors controlled by laser light, is likely to have applications in making sensors and quantum devices for advanced instrumentation, improve mineral exploration and measure tiny electromagnetic signals.Read moreRead less
The Dark-side of the Milky Way. Astronomers have long sought to determine the 3-dimensional structure of our Galaxy, the Milky Way, with limited success owing to its immense size and obscuration by dust at optical wavelengths. We know more about structure of tens of thousands of other galaxies than we do about the structure of the Milky Way on the far-side of the Galactic Centre. This program will use Australian infrastructure to make the most accurate distance measurements to date of the far-si ....The Dark-side of the Milky Way. Astronomers have long sought to determine the 3-dimensional structure of our Galaxy, the Milky Way, with limited success owing to its immense size and obscuration by dust at optical wavelengths. We know more about structure of tens of thousands of other galaxies than we do about the structure of the Milky Way on the far-side of the Galactic Centre. This program will use Australian infrastructure to make the most accurate distance measurements to date of the far-side of the Milky Way visible from the Southern hemisphere, completing the 3-dimensional picture of our Galaxy. These results will be leveraged to yield accurate distances, providing fundamental information on the stellar masses, luminosities, and ages.Read moreRead less
Deep ocean thermodynamics and climate change. This project aims to obtain new insights into the thermodynamic and transport properties of mixtures containing water, particularly at high pressures, that impact directly on our understanding of climate change processes.

This project aims to obtain new insights into the thermodynamic and transport properties of mixtures containing water, particularly at high pressures, that impact directly on our understanding of climate change processes. The project will involve the use of a polarisable potential for water which has recently been demonstrated to yield predictions of high accuracy. It will be used to model saline water mixtures containing carbon dioxide, resulting in valuable data for thermodynamic properties of the world's oceans. These data are of crucial importance for accurate climate change predictions and as such the project will have an important impact on understanding our changing environment.Read moreRead less
Anomalous Structural Response in Porous Framework Materials. This project targets a key missing link in understanding the host-guest properties of porous framework materials, namely, the dynamic response of host lattices to their external environment and to the inclusion of molecular guests. By combining advanced chemical, physical and structural measurements the project expects to provide the first concerted picture of materials behaviour across an array of scientific and technological settings ....Anomalous Structural Response in Porous Framework Materials. This project targets a key missing link in understanding the host-guest properties of porous framework materials, namely, the dynamic response of host lattices to their external environment and to the inclusion of molecular guests. By combining advanced chemical, physical and structural measurements the project expects to provide the first concerted picture of materials behaviour across an array of scientific and technological settings, with particular focus given to industrially relevant ‘real world’ conditions. This promises to greatly inform the on-going chemical design, formulation and process engineering of these materials, in turn accelerating their development in gas separation, energy storage and device componentry applications.Read moreRead less

For decades astronomers have puzzled over the connection between the structure and evolution of galaxies and the role played by host environments. This project aims to resolve this problem by combining multi-wavelength observations, multi-component simulations, and pioneering data analysis using artificial intelligence. In particular, we target the nearby Fornax galaxy cluster as a laboratory for studying galaxy formation in dense environments. Using our novel machine learning techniques, we will elucidate the physical mechanisms that drive the rapid evolution of star formation, galactic nuclei, and gas and dust content within Fornax. Our predictions will benefit ongoing and future surveys at the national and international level. Read moreRead less
