The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on trop ....The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.Read moreRead less
LATERAL GENE TRANSFER, GENOME EVOLUTION AND THE EMERGENCE OF NEW DISEASES CAUSED BY FUNGAL PATHOGENS IN THE PLEOSPORALES. Normal evolution involves the transfer of genes within species. The modest variation between progeny powers natural selection. Lateral gene transfer is the movement of genetic material between species. It allows for large evolutionary steps. Although common in bacteria, it has rarely been described convincingly in higher organisms such as fungi, plants or animals. We have evi ....LATERAL GENE TRANSFER, GENOME EVOLUTION AND THE EMERGENCE OF NEW DISEASES CAUSED BY FUNGAL PATHOGENS IN THE PLEOSPORALES. Normal evolution involves the transfer of genes within species. The modest variation between progeny powers natural selection. Lateral gene transfer is the movement of genetic material between species. It allows for large evolutionary steps. Although common in bacteria, it has rarely been described convincingly in higher organisms such as fungi, plants or animals. We have evidence that one group of fungal pathogens is particularly adept at acquiring new genes that enable them to cause new diseases. We will determine the mechanism and frequency of gene transfer in this group. The work had fundamental significance in evolutionary biology, in the emergence of new diseases and in the use of genetically-modified organisms.Read moreRead less
The nature, extent and effect of infant removal by child protection. This project aims to provide new knowledge about the nature, extent and effect of removals of babies from their parents in Australia. Removal is the highest level of intervention by the child protection system, and one which some mothers experienced on multiple occasions. Little is known, however, about its incidence and effects, nor whether there are over-represented groups (e.g. Aboriginal mothers and babies) who would respon ....The nature, extent and effect of infant removal by child protection. This project aims to provide new knowledge about the nature, extent and effect of removals of babies from their parents in Australia. Removal is the highest level of intervention by the child protection system, and one which some mothers experienced on multiple occasions. Little is known, however, about its incidence and effects, nor whether there are over-represented groups (e.g. Aboriginal mothers and babies) who would respond to targeted interventions. This project aims to identify appropriate early intervention and prevention strategies, preventing the need for babies to spend their whole childhood in care at great financial and societal cost.Read moreRead less
Work-related fatal and non-fatal accidents and injuries and exposure to workplace hazards in migrant workers in Australia. Do migrants have worse workplace conditions and more work-related accidents and injuries than Australian-born workers? This project will analyse national deaths and hospital discharge data, and determine best practice methods to include migrant workers in a future cross-sectional study looking at occupational health and safety.
Technical Change, Productivity Growth and Pricing in Australian Manufacturing. We examine productivity growth and price competitiveness of Australian manufacturing by estimating an econometric model for aggregate manufacturing and as well as individual industries. The parameter estimates from the econometric model are used to identify the separate impacts on productivity growth and price changes due to technical change, economies of scale, capacity utilization and market power. We then estimate ....Technical Change, Productivity Growth and Pricing in Australian Manufacturing. We examine productivity growth and price competitiveness of Australian manufacturing by estimating an econometric model for aggregate manufacturing and as well as individual industries. The parameter estimates from the econometric model are used to identify the separate impacts on productivity growth and price changes due to technical change, economies of scale, capacity utilization and market power. We then estimate how each separate impact is affected by industry characteristics, including seller concentration and investment in physical, human and intellectual capital, and policy related variables, such as tariff rates and degree of unionisation of the labour force. This will provide an important contribution of the knowledge of how the economic environment and government policies impact on productivity growth and the international competitiveness of Australian manufacturing.Read moreRead less
Lived experiences of treatment for hepatitis C in Australia. This project aims to support uptake of new hepatitis C treatments. With the introduction of new treatments in 2016, the Australian Government adopted the WHO’s goal of eliminating the disease by 2030. While early treatment rates were high, they have since plateaued, with stigma and poor information considered key obstacles. This project will generate new knowledge on treatment decisions and experiences, using a proven qualitative metho ....Lived experiences of treatment for hepatitis C in Australia. This project aims to support uptake of new hepatitis C treatments. With the introduction of new treatments in 2016, the Australian Government adopted the WHO’s goal of eliminating the disease by 2030. While early treatment rates were high, they have since plateaued, with stigma and poor information considered key obstacles. This project will generate new knowledge on treatment decisions and experiences, using a proven qualitative methodology. In doing so, it will produce a website covering personal experiences of treatment, issues in treatment decision-making, and advice on enhancing life on treatment and after. It will tackle hepatitis C-related stigma, and inform and benefit potential treatment users, families and relevant professionals.

CNVs have been shown to contribute significantly to phenotypic differences in humans, including diseas ....The More the Merrier? Investigating copy number variation in Brassicas. This project intends to develop an understanding of how gene copy number variation affects disease susceptibility to help in the design of novel plant protection strategies. Gene copy number variants (CNVs) are segments of DNA that have been duplicated or lost in the genome of one individual or line with respect to another. CNVs have been shown to contribute significantly to phenotypic differences in humans, including disease susceptibility, and the same seems to apply in plants. This project aims to apply the genome sequences for Brassica species to detect CNVs from re-sequencing data. Knowing how this variation affects an individual or line’s disease susceptibility, especially to the devastating fungal pathogen blackleg, could improve plant protection strategies and crop production.Read moreRead less
Exploring the gene regulation networks governing mitochondrial biogenesis in Arabidopsis.

Mitochondria, subcellular organelles that perform many functions indispensable to plant growth and productivity, are dynamic compartments whose protein complement changes dramatically during plant development and under stress. Yet, the cellular processes that regulate the production of these organelles are virtually unknown. By combining conventional approaches with an extremely powerful holistic method for simultaneously examining the expression patterns of every gene in the model plant Arabidopsis, this project will identify proteins that regulate mitochondrial biosynthesis and uncover the gene networks that these proteins control. The project outcomes will provide new opportunities for the rational manipulation of plant growth and productivity.Read moreRead less
