Turning back the clock on brain cell aging. This proposal aims to determine the role of fundamental epigenetic mechanisms in the process of aging and whether modulation of the epi-genome underpins an improvement in cognitive function. It combines the fields of epigenetics, neurosciences and mathematics to delineate the dynamics of DNA methylation and histone modification marking on the transcriptome during normal, healthy aging. The outcomes will provide significant new knowledge of the variable ....Turning back the clock on brain cell aging. This proposal aims to determine the role of fundamental epigenetic mechanisms in the process of aging and whether modulation of the epi-genome underpins an improvement in cognitive function. It combines the fields of epigenetics, neurosciences and mathematics to delineate the dynamics of DNA methylation and histone modification marking on the transcriptome during normal, healthy aging. The outcomes will provide significant new knowledge of the variable cognitive decline that occurs in healthy aging and why some populations age less successfully than others do. Better understanding of the impact of environmental change on the biology of aging has potential community benefits.Read moreRead less
Using genetics to reconstruct the peopling and diversification of Sahul. A recent landmark study has revealed that people who first arrived on Sahul (the landmass connecting Australia with New Guinea) remained largely genetically isolated from subsequent migrations. However, there is still little known about the route(s) taken into Sahul, or how adaptation has shaped the enormous diversity now observed across Indigenous Australians and Papuans. This project aims to look at these issues by applyi ....Using genetics to reconstruct the peopling and diversification of Sahul. A recent landmark study has revealed that people who first arrived on Sahul (the landmass connecting Australia with New Guinea) remained largely genetically isolated from subsequent migrations. However, there is still little known about the route(s) taken into Sahul, or how adaptation has shaped the enormous diversity now observed across Indigenous Australians and Papuans. This project aims to look at these issues by applying phylogenetic and population genetic tools to the largest genetic dataset yet analysed from populations across Australia, New Guinea, and Island South East Asia. The outcomes of the project should reveal both the route(s) taken into Sahul and how adaptation has shaped the diversity now observed in descendants of the colonisation.Read moreRead less
Understanding the role of terrain geometry in eruptive bushfire behaviour. This project aims to improve understanding of the physical processes that cause eruptive bushfire behaviour, otherwise known as fire blow-up. Eruptive fire behaviour, characterised by rapid and unexpected escalation in fire intensity and rate of spread, is a global phenomenon that poses a major threat to fire-fighter safety and can seriously compromise bushfire suppression efforts. This project will address the role that ....Understanding the role of terrain geometry in eruptive bushfire behaviour. This project aims to improve understanding of the physical processes that cause eruptive bushfire behaviour, otherwise known as fire blow-up. Eruptive fire behaviour, characterised by rapid and unexpected escalation in fire intensity and rate of spread, is a global phenomenon that poses a major threat to fire-fighter safety and can seriously compromise bushfire suppression efforts. This project will address the role that terrain geometry plays in the incidence of fire eruption, through consideration of its effect on the attachment of flames to a surface. Expected outcomes include a dynamic fire spread modelling framework and the provision of better advice to bushfire authorities concerning fire blow-up.Read moreRead less
The genomic history of Indigenous Australia. The aim of the project is to analyse genomic DNA from historic hair samples collected by anthropological expeditions in the early 20th century to generate a detailed genetic map of Aboriginal Australia and to reconstruct Australia’s pre-European genetic history. The genomic data and detailed contextual and genealogical information from museum archives will be used to work with Aboriginal individuals to trace past population movements and augment oral ....The genomic history of Indigenous Australia. The aim of the project is to analyse genomic DNA from historic hair samples collected by anthropological expeditions in the early 20th century to generate a detailed genetic map of Aboriginal Australia and to reconstruct Australia’s pre-European genetic history. The genomic data and detailed contextual and genealogical information from museum archives will be used to work with Aboriginal individuals to trace past population movements and augment oral historical records. The project aims to reconstruct the first detailed genomic history of indigenous Australia, including adaptation to the challenging Australian environment, and to generate important information for indigenous communities and the Australian public more widely.Read moreRead less
Babera dariadya yewing (Echoes of a flawed truth): investigating theory and practice on the interplay between bullying and racism. The negative impact of bullying and racism is being increasingly documented for Aboriginal youth, yet little attempt has been made to understand the differential impact of these stressors on the wellbeing and identity of Aboriginal Australian youth. This project will seek to address this issue, to guide future action-based research.
Understanding the role of deep flaming in violent pyroconvective events. This project aims to improve the prediction of firestorms by combining state-of-the-art knowledge of dynamic bushfire behaviour with atmospheric models to provide a comprehensive understanding of how the heat and moisture released by a bushfire interacts with ambient atmospheric instability to produce extreme fire events. Firestorms represent the most extreme and catastrophic phase of development of a bushfire. They often c ....Understanding the role of deep flaming in violent pyroconvective events. This project aims to improve the prediction of firestorms by combining state-of-the-art knowledge of dynamic bushfire behaviour with atmospheric models to provide a comprehensive understanding of how the heat and moisture released by a bushfire interacts with ambient atmospheric instability to produce extreme fire events. Firestorms represent the most extreme and catastrophic phase of development of a bushfire. They often cause broad-scale loss of property, environmental damage and human fatalities. Firestorms cannot be suppressed, and so accurate and timely warnings of their occurrence, combined with appropriate community responses, are the only way of mitigating their effects. Better understanding of extreme fire processes may improve mitigation planning, community safety, environmental outcomes and emergency response measures.Read moreRead less
Investigation of atypical bushfire spread driven by the interaction of wind, terrain and fire. Large bushfires continue to pose a significant risk to communities in south-eastern Australia. Despite this, there is still very little known about the processes driving the development of large bushfires. This project aims to improve understanding of extreme fire processes and thus improve mitigation planning, community safety and environmental outcomes.
Indigenous mathematical transforms. A class of mathematical transforms, or systematic conversions between related spaces or objects, was practised by some Aboriginal and Torres Strait Islander groups. Such transforms from ground to night sky were used in long-distance route-recording and wayfinding techniques. This project aims to elucidate these transforms, and to use this knowledge to extend the mathematical framework and applications of Fourier analysis. There is significant potential for new ....Indigenous mathematical transforms. A class of mathematical transforms, or systematic conversions between related spaces or objects, was practised by some Aboriginal and Torres Strait Islander groups. Such transforms from ground to night sky were used in long-distance route-recording and wayfinding techniques. This project aims to elucidate these transforms, and to use this knowledge to extend the mathematical framework and applications of Fourier analysis. There is significant potential for new mathematics to emerge at this exciting interface of Indigenous/non-Indigenous knowledge. Expected outcomes are interdisciplinary research training for Indigenous students and new understanding of Indigenous sciences. Emerging big data technologies such as holography may benefit.

Deficit Discourse and Indigenous Education. This project investigates the prevalence of ‘deficit discourse’ and its influence on Indigenous education. Deficit discourse frames Indigenous identity in a narrative of negativity and deficiency. Recent work indicates that deficit discourse is active in policy, public debate, pedagogy and practice, and its prevalence in Indigenous education influences student performance. By mapping the discursive environment and analysing education programs that reje ....Deficit Discourse and Indigenous Education. This project investigates the prevalence of ‘deficit discourse’ and its influence on Indigenous education. Deficit discourse frames Indigenous identity in a narrative of negativity and deficiency. Recent work indicates that deficit discourse is active in policy, public debate, pedagogy and practice, and its prevalence in Indigenous education influences student performance. By mapping the discursive environment and analysing education programs that reject the deficit model, this project assesses whether its removal improves outcomes for Indigenous students. This project provides an original approach to challenge entrenched perceptions, resulting in tangible benefits for the Australian education system and the communities that it serves.Read moreRead less
