Selectivity enhancement in separation science using responsive materials. Increasing public demand for quality products from the chemical, pharmaceutical, biotechnology and food industries requires access to innovative methods of chemical analysis. This project will establish a new class of separation materials of enhanced selectivity and resolving power for the fast, sensitive and reliable analysis of these products.
Carbonaceous adsorbents for ultra-high performance liquid chromatography. This project aims to develop a new generation of mechanically and thermally stable carbon-nanocarbon composite adsorbents for ultra-high-performance liquid chromatography. The structure of adsorbents will be constructed according to advanced core-shell design with non-porous carbon central core and porous shell formed by highly ordered uniform nanocarbon particles.

This project aims to develop a new generation of mechanically and thermally stable carbon-nanocarbon composite adsorbents for ultra-high-performance liquid chromatography. The structure of adsorbents will be constructed according to advanced core-shell design with non-porous carbon central core and porous shell formed by highly ordered uniform nanocarbon particles. The unique properties of carbon-nanocarbon composite adsorbents will put liquid chromatography to qualitatively new levels of the separation performance that may open new possibilities for medicine and biodiagnostics. The resulting technology also has a strong potential to be used in other priority areas such as preparation of electrodes and supercapacitors for energy storage devices.Read moreRead less
Algebraically informed models of biological sequence evolution. To make sense of the patterns they see in the natural world, biologists across fields as diverse as genetics, epidemiology and biogeography need an accurate picture of evolutionary history. DNA sequences provide an exciting means to establish this picture of the past, but to decode it successfully requires mathematical models of how DNA evolves. Mathematical inconsistencies have been identified with current approaches. In particular ....Algebraically informed models of biological sequence evolution. To make sense of the patterns they see in the natural world, biologists across fields as diverse as genetics, epidemiology and biogeography need an accurate picture of evolutionary history. DNA sequences provide an exciting means to establish this picture of the past, but to decode it successfully requires mathematical models of how DNA evolves. Mathematical inconsistencies have been identified with current approaches. In particular, understanding the effect of natural selection in different parts of the tree of life requires models that behave robustly in the face of shifting evolutionary processes. This project aims to use insights from algebraic methods to construct mathematically consistent models of wide biological utility.Read moreRead less
Does mother know best? Unifying proximate causation and ultimate explanation in mammalian sex allocation. The study of parental effects is a fundamental area in evolutionary ecology, but is characterised by poor integration of theory (ultimate causation) and physiology (proximate causation). This is true in sex allocation research that focuses almost exclusively on ultimate causation without integrating the physiological mechanisms for sex ratio adjustment. Using a combination of experiments and ....Does mother know best? Unifying proximate causation and ultimate explanation in mammalian sex allocation. The study of parental effects is a fundamental area in evolutionary ecology, but is characterised by poor integration of theory (ultimate causation) and physiology (proximate causation). This is true in sex allocation research that focuses almost exclusively on ultimate causation without integrating the physiological mechanisms for sex ratio adjustment. Using a combination of experiments and modelling, the project addresses this gap in understanding mammalian sex allocation, specifically: the lack of known mechanism; the connection between proximate mechanistic explanation and adaptive fitness explanations; and, knowledge on constraints. This project argues that one mechanism, pre-implantation glucose levels, links adaptive hypotheses with proximate causation. Read moreRead less
Increasing Behavioural Flexibility in Children with Autism. Autism is a developmental disorder associated with social and language deficits and an abnormal resistance to change. The number of children diagnosed with autism is increasing, as are the social and economic costs to Australia. While programs exist for teaching social and language skills, effective strategies for teaching the child how to cope with change are lacking. This project aims to discover educational procedures for increasing ....Increasing Behavioural Flexibility in Children with Autism. Autism is a developmental disorder associated with social and language deficits and an abnormal resistance to change. The number of children diagnosed with autism is increasing, as are the social and economic costs to Australia. While programs exist for teaching social and language skills, effective strategies for teaching the child how to cope with change are lacking. This project aims to discover educational procedures for increasing the child's tolerance for and ability to cope with change. By doing so, the project will benefit Australian families and teachers who need effective, research-based procedures for managing this core feature of autism. Read moreRead less
Resolving dissolved organic matter: new multi-dimensional separation approaches. To fully understand and model global carbon cycles the source, nature and fate of oceanic dissolved organic carbon is an essential element. This project will develop, model and apply new orthogonol and complementary separation science based technologies to further the comprehensive characterisation and understanding of these complex systems.
An efficient approach to the computation of bacterial evolutionary distance. This project aims to apply advanced mathematical tools to improve our understanding of bacterial evolution. Bacteria account for as much total Earth biomass as all plant species put together, and have an unparalleled ability to evolve quickly and adapt to changing environments. Unfortunately, the existing mathematical models used to model bacterial evolution are generally computationally intractable. This project will r ....An efficient approach to the computation of bacterial evolutionary distance. This project aims to apply advanced mathematical tools to improve our understanding of bacterial evolution. Bacteria account for as much total Earth biomass as all plant species put together, and have an unparalleled ability to evolve quickly and adapt to changing environments. Unfortunately, the existing mathematical models used to model bacterial evolution are generally computationally intractable. This project will rectify this situation by using representation theory to transform combinatorial group theory into linear algebra, allowing for the application of advanced methods of numeric approximation. This will provide a better understanding of how bacteria evolve and improve our ability to manage their impact.Read moreRead less
Lags and legacies: antecedent effects on grassland biomass response to carbon dioxide. This project aims to assess how past conditions influence grassland responses to the rising atmospheric concentration of carbon dioxide. High CO2 concentrations should stimulate productivity but in grasslands this is rarely realised because other, mostly unknown, factors constrain the response. By synthesising data from past experiments, this project aims to determine exactly why grasslands fail to realise the ....Lags and legacies: antecedent effects on grassland biomass response to carbon dioxide. This project aims to assess how past conditions influence grassland responses to the rising atmospheric concentration of carbon dioxide. High CO2 concentrations should stimulate productivity but in grasslands this is rarely realised because other, mostly unknown, factors constrain the response. By synthesising data from past experiments, this project aims to determine exactly why grasslands fail to realise the full productivity benefits of increased CO2 and when this will happen. This should improve predictions of carbon exchange and indicating the best direction for climate change adaptation measures.Read moreRead less
