Australia is highly dependent on fossil fuels for energy production and transport, and this dependence is growing. Wide spread substitution of liquid hydrocarbon fuels by indigenous renewable bio-oil has the potential to improve Australian's energy outlook and assist in reaching greenhouse gas targets. Understanding the interrelationships between the physical and chemical properties of bio-oil, its atomisation, droplet formation and combustion physics is fundamental to the delivery of an efficient and reliable combustion process using this fuel. Measurements using laser based diagnostics of the atomisation flow, droplet formation and combustion process will provide the experimental data to understand this complex interrelationship.Read moreRead less
Airborne ultrafine particles in Australian cities. There is an acute deficiency of knowledge in Australia on urban airborne ultrafine particles, originating from transport and other anthropogenic sources, which pose significant health and environmental risks. The aim of this project is to address this deficiency by an extensive multi-city, cross-disciplinary study using state of the art instrumentation and data analytic techniques. The outcome will be an in depth, quantitative insight into the c ....Airborne ultrafine particles in Australian cities. There is an acute deficiency of knowledge in Australia on urban airborne ultrafine particles, originating from transport and other anthropogenic sources, which pose significant health and environmental risks. The aim of this project is to address this deficiency by an extensive multi-city, cross-disciplinary study using state of the art instrumentation and data analytic techniques. The outcome will be an in depth, quantitative insight into the characteristics of the particles, their sources and spatial and temporal variation across different urban areas and time scales. Further, the impacts of changing fuels, vehicle technologies, and climate on future trends of the particles will be elucidated.Read moreRead less
Promoting active travel and public transport for a post-pandemic world. In many major cities, COVID-19 stimulated the provision of open streets, pop up bike lanes and widened pedestrian access, prompting unprecedented increases cycling and walking. While this type of infrastructure has always been supported by urban planners and designers, the pandemic has served as a vital inflection point, enabling cities to pursue long-term sustainable transport initiatives, including investment in Active Tra ....Promoting active travel and public transport for a post-pandemic world. In many major cities, COVID-19 stimulated the provision of open streets, pop up bike lanes and widened pedestrian access, prompting unprecedented increases cycling and walking. While this type of infrastructure has always been supported by urban planners and designers, the pandemic has served as a vital inflection point, enabling cities to pursue long-term sustainable transport initiatives, including investment in Active Travel (AT). There is an opportunity to promote AT as part of an integrated transport strategy, and to develop tools for the robust evaluation of AT impacts to inform future investment strategies. This proposal will provide our partner organisation Transport for New South Wales (with the knowledge required to achieve this.

Findings from this project will be used to improve safety policies, regulations and practices that aim to minimise the number of accidents and incidents in Australian waters.
A systemic model to underpin enhanced management of powered-two-wheelers as part of a safe, sustainable transport system. Better management of motor scooters and motorbikes (Powered-2-wheelers or P2W) will deliver economic, environmental and social benefits. Road crashes involving P2Ws cost the Australian community in excess of $2 billion per annum. There are also the broader social impacts for crash victims, their families and communities from the potentially long-term pain, grief and debilitat ....A systemic model to underpin enhanced management of powered-two-wheelers as part of a safe, sustainable transport system. Better management of motor scooters and motorbikes (Powered-2-wheelers or P2W) will deliver economic, environmental and social benefits. Road crashes involving P2Ws cost the Australian community in excess of $2 billion per annum. There are also the broader social impacts for crash victims, their families and communities from the potentially long-term pain, grief and debilitating injuries. This project will provide insight into how the incidence and costs associated with P2W crashes can be reduced. In addition, congestion costs in each of Australia's capital cities are on the order of $3 billion per annum and there is potential for P2W research to reduce not only that cost but also the broader environmental impacts of travel by providing an alternative to cars.Read moreRead less
Evolutionary origins of sexual parasitism in an Australian freshwater fish. Carp gudgeons are the most abundant, widespread and biodiverse freshwater fishes in southeastern Australia. The unacknowledged presence of many cryptic species and sexually-parasitic lineages severely taints all research on this cornerstone group. This project aims to provide unrivalled evolutionary, genomic, and taxonomic insights into this new instance of vertebrate sexual parasitism, which offers a unique mix of resea ....Evolutionary origins of sexual parasitism in an Australian freshwater fish. Carp gudgeons are the most abundant, widespread and biodiverse freshwater fishes in southeastern Australia. The unacknowledged presence of many cryptic species and sexually-parasitic lineages severely taints all research on this cornerstone group. This project aims to provide unrivalled evolutionary, genomic, and taxonomic insights into this new instance of vertebrate sexual parasitism, which offers a unique mix of research advantages not displayed by any other sexual/unisexual complex. The knowledge gained could impact many research fields, including evolutionary theory addressing the unexplainable prevalence of sex, native fish ecology, and environmental monitoring of the Murray-Darling Basin, an ecosystem of world significance.Read moreRead less
Restoring amphibian populations in chytrid-impacted landscapes. This project aims to address an outstanding problem in wildlife disease ecology: how can we enable susceptible amphibians to persist in the face of the chytrid pathogen, which has devastated amphibian biodiversity? This project expects to generate new knowledge by experimentally trialling two highly promising interventions: immunising animals and creating disease refugia through simple habitat manipulations. Outcomes of this project ....Restoring amphibian populations in chytrid-impacted landscapes. This project aims to address an outstanding problem in wildlife disease ecology: how can we enable susceptible amphibians to persist in the face of the chytrid pathogen, which has devastated amphibian biodiversity? This project expects to generate new knowledge by experimentally trialling two highly promising interventions: immunising animals and creating disease refugia through simple habitat manipulations. Outcomes of this project include a framework for predicting how interventions might enable host-pathogen coexistence. This project should provide significant benefits including enhanced understanding of wildlife disease dynamics that will pave the way for interventions to restore amphibian biodiversity in chytrid-impacted landscapes.Read moreRead less
Fluid-thermal-structural interactions on high-speed aerospace vehicles. Sixteen years after the retirement of Concorde, high-speed commercial flight is once again on the rise with the development of new supersonic business jets and small airliners as well as hypersonic transport and reusable space launch systems. Robust and efficient designs for these light-weight vehicles must address the problem of aerodynamic heating and its effect on structural performance and lifing.

Sixteen years after the retirement of Concorde, high-speed commercial flight is once again on the rise with the development of new supersonic business jets and small airliners as well as hypersonic transport and reusable space launch systems. Robust and efficient designs for these light-weight vehicles must address the problem of aerodynamic heating and its effect on structural performance and lifing. This project will design and perform first-of-kind experiments that reproduce the complex fluid-thermal-structural interactions representative of those experienced by these aircraft and rockets. We will then use these measurements to assess, validate and improve the current state-of-the-art of simulation and modelling approaches for design.Read moreRead less
Fluid-structural interactions in high-speed flows. This project aims to perform experiments to measure fluid-structure interaction in hypersonic flows. The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters.

The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters. Accurate prediction of the behaviour and lifetime of structural components subject to these fluid-structural interactions, in which the deformation of the structure induced by the local flow field, can in turn influence this flow field. This coupling can result in damage or even catastrophic structural failure and thus robust design tools must be developed to avoid this.Read moreRead less
Improving external validity of stated choice experiments. This project aims to deliver more accurate estimates of choice behaviour by reducing biases due to choice task complexity in surveys as well as design artefacts. Extracting 'true' preferences is challenging, not only due to possible hypothetical bias, but also due to increasingly complex choice tasks and the existence of design artefacts. This project will investigate the latter two in the context of marketing, transport, health, and envi ....Improving external validity of stated choice experiments. This project aims to deliver more accurate estimates of choice behaviour by reducing biases due to choice task complexity in surveys as well as design artefacts. Extracting 'true' preferences is challenging, not only due to possible hypothetical bias, but also due to increasingly complex choice tasks and the existence of design artefacts. This project will investigate the latter two in the context of marketing, transport, health, and environmental economics, and proposes new methodologies to extract preferences that more closely reflect true behaviour in real markets.Read moreRead less
