This project aims to develop techniques to solve the issue in information security of unauthorised information flow resulting from competition for shared hardware resources. The project will combine operating systems design, formal hardware models, information-flow reasoning and theorem proving to achieve a goal that is widely considered infeasible. The project is expected to result in a system that prevents leakage of critical information, such as encryption keys, through timing channels. This should prevent sophisticated attacks on public clouds, mobile devices and military-grade cross-domain devices.Read moreRead less
The rise of mistrust: Digital platforms and trust in news media. This project aims to investigate how trust and mistrust in news changes audiences’ behaviours as they increasingly access news through digital platforms. Observing the global crisis of trust, the project will undertake a longitudinal analysis of trust and mistrust in news, a four-country experiment that links trust and audience responses, and an in-depth qualitative study that provides specific contexts of these choices. The resear ....The rise of mistrust: Digital platforms and trust in news media. This project aims to investigate how trust and mistrust in news changes audiences’ behaviours as they increasingly access news through digital platforms. Observing the global crisis of trust, the project will undertake a longitudinal analysis of trust and mistrust in news, a four-country experiment that links trust and audience responses, and an in-depth qualitative study that provides specific contexts of these choices. The research will directly benefit policy makers, as it addresses questions of how to better secure trustworthy news content in an age of increasing dominance of digital platforms that algorithmically sort the range of news available to the Australian public.

Impact of evaluation-based funding on the content of scientific research. Evidence suggests that evaluation-based funding mechanisms trigger adaptive behaviour in scientists, leading to unintended changes in knowledge production. However, there is no conclusive evidence about when (under what circumstances), how (by what processes) and with what effects researchers adapt to these mechanisms. This study aims to answer these crucial questions. To overcome the methodological weaknesses of earlier s ....Impact of evaluation-based funding on the content of scientific research. Evidence suggests that evaluation-based funding mechanisms trigger adaptive behaviour in scientists, leading to unintended changes in knowledge production. However, there is no conclusive evidence about when (under what circumstances), how (by what processes) and with what effects researchers adapt to these mechanisms. This study aims to answer these crucial questions. To overcome the methodological weaknesses of earlier studies, a comparative investigation of several research fields and universities will be conducted, combining for the first time: qualitative interviews, ethnographic observations and bibliometric studies. It will enhance Australian research policy with a critical assessment of existing research funding models.Read moreRead less

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
Controlling the rate of transcription and translation of Rubisco transgenes effectively in higher-plant plastids. Genetic transformation of the circular genome of the plastids provides a containable means for modifying plant growth by manipulating photosynthesis. Although the transformation mechanism is precise, predicting the level of foreign gene expression is difficult because the amounts of messenger RNA and protein produced by foreign genes in plastids varies widely, even when the protein a ....Controlling the rate of transcription and translation of Rubisco transgenes effectively in higher-plant plastids. Genetic transformation of the circular genome of the plastids provides a containable means for modifying plant growth by manipulating photosynthesis. Although the transformation mechanism is precise, predicting the level of foreign gene expression is difficult because the amounts of messenger RNA and protein produced by foreign genes in plastids varies widely, even when the protein assembles without difficulty. This project will devise strategies for controlling this variability that will facilitate attempts to exploit plastid transformation for transplanting better versions of the photosynthetic CO2-fixing enzyme, Rubisco, into plants to improve their growth efficiency in terms of water, fertiliser and light use.Read moreRead less
Practical strategies for engineering the CO2-fixing enzyme, Rubisco, whose subunits are encoded in different subcellular compartments. My recent replacement of the plant CO2-fixing enzyme, Rubisco, with a less efficient bacterial version, with a single type of subunit encoded by a single gene, demonstrated the feasibility of replacing Rubisco. This encourages ongoing attempts to replace plant Rubisco with more efficient versions that would allow the plants to grow with less water, fertiliser or ....Practical strategies for engineering the CO2-fixing enzyme, Rubisco, whose subunits are encoded in different subcellular compartments. My recent replacement of the plant CO2-fixing enzyme, Rubisco, with a less efficient bacterial version, with a single type of subunit encoded by a single gene, demonstrated the feasibility of replacing Rubisco. This encourages ongoing attempts to replace plant Rubisco with more efficient versions that would allow the plants to grow with less water, fertiliser or light. The most efficient Rubiscos are more complex, with two different types of subunits which, in plants, are encoded in different subcellular compartments (nucleus and plastid). This proposal addresses the challenges associated with complementary engineering both genomes to substitute foreign Rubiscos into higher-plant chloroplasts.Read moreRead less

Ubiquitous communications service is the most important element of today's societies. In urban and rural areas of the country as well as at the time of natural disasters such as bushfires, floods, cyclones, it is vital to devise alternative schemes to create and sustain on-demand telecommunications services. In most cases it is not the lack of technology that hinders the implementation of a reliable communications service, but it is the resource allocation. In this project we propose a novel sustainable resource management framework inspired by natural ecological systems to solve the above problem. Upon completion, Australia will be in forefront of technologies related to the management of complex networks.Read moreRead less
