Optimising the search for the next discovery in particle physics. This project aims to uncover the new theory of particle physics that can simultaneously explain the Higgs mechanism, the presence of dark matter and the current abundance of matter over antimatter in our universe. This is not possible with current theories. This project aims to find viable theories using a wide range of data from particle astrophysics and collider experiments. With the resulting knowledge, this project aims to des ....Optimising the search for the next discovery in particle physics. This project aims to uncover the new theory of particle physics that can simultaneously explain the Higgs mechanism, the presence of dark matter and the current abundance of matter over antimatter in our universe. This is not possible with current theories. This project aims to find viable theories using a wide range of data from particle astrophysics and collider experiments. With the resulting knowledge, this project aims to design, optimise and implement better searches for new physics at the Large Hadron Collider (LHC). The new LHC results will be used to either determine the correct explanation for any new discoveries or alternatively to provide definitive limits on new theories. The results will be used to make high impact statements on the design of future facilities.Read moreRead less
Nanodiamond in glass: a new approach to nanosensing. This work will develop optical materials enriched with diamond nanoparticles. This will enable the magnetic field sensitivity of diamond nanoparticles to be combined with the capacity of micro/nanostructured optical fibres to enhance the interaction of light with matter. The outcome will be tools for probing biological processes on the nanoscale.
Investigating the evolution of innate and adaptive cellular immunity. This proposal aims to assess the impact of geographical and genetic isolation of the Australian Indigenous population on adaptive and innate immune systems. The project will use novel DNA sequencing approaches to generate the high resolution sequences of two genetic loci that regulate innate and adaptive immune responses, the major histocompatibility complex locus and the killer cell immunoglobulin-like receptor locus. In an i ....Investigating the evolution of innate and adaptive cellular immunity. This proposal aims to assess the impact of geographical and genetic isolation of the Australian Indigenous population on adaptive and innate immune systems. The project will use novel DNA sequencing approaches to generate the high resolution sequences of two genetic loci that regulate innate and adaptive immune responses, the major histocompatibility complex locus and the killer cell immunoglobulin-like receptor locus. In an initial screen, distinct variants and combinations of these genes were identified. This project aims to interrogate how variation in these critical genes impacts on the function of cytotoxic lymphocytes, providing insights into the evolutionary drivers of immune recognition mechanisms.Read moreRead less
Gas Phase Reactivity of Charged Peptide and DNA Radicals: Fundamentals and Applications. Radicals derived from the "molecules of life", proteins and DNA, play both beneficial (e.g. enzyme catalysis) and deleterious roles (e.g. protein and DNA damage associated with disease). Two electrospray ionisation mass spectrometry approaches have been discovered to generate charged radicals of related models systems (e.g. peptides and nucleobases). The gas phase chemistry of these species is a largely unch ....Gas Phase Reactivity of Charged Peptide and DNA Radicals: Fundamentals and Applications. Radicals derived from the "molecules of life", proteins and DNA, play both beneficial (e.g. enzyme catalysis) and deleterious roles (e.g. protein and DNA damage associated with disease). Two electrospray ionisation mass spectrometry approaches have been discovered to generate charged radicals of related models systems (e.g. peptides and nucleobases). The gas phase chemistry of these species is a largely unchartered area! We will examine the fundamental chemistry (unimolecular and bimolecular reactions) of these systems and build upon some exciting preliminary results which suggest potential applications (e.g. as a proteomics tool to sequence and distinguish between leucine and isoleucine residues in peptides).Read moreRead less
Structure and activity of host-defence peptides from Australian anurans: anticancer agents, neuropeptides and nNOS inhibitors. We have discovered peptides that may have clinical applications. This is significant as these molecules may have one or more of the following properties. They may have anti-cancer effects; they may increase the effectiveness of the immune system by enhancing lymphocyte formation; and, they may act to reduce inflammation, stroke or cardiac conditions by controlling nitri ....Structure and activity of host-defence peptides from Australian anurans: anticancer agents, neuropeptides and nNOS inhibitors. We have discovered peptides that may have clinical applications. This is significant as these molecules may have one or more of the following properties. They may have anti-cancer effects; they may increase the effectiveness of the immune system by enhancing lymphocyte formation; and, they may act to reduce inflammation, stroke or cardiac conditions by controlling nitric oxide formation. Another national benefit is that personnel involved in this project are trained to the highest international standards in peptide chemistry/mass spectrometry/nuclear magnetic resonance: currently, there are not enough trained scientists in this area to meet demand.Read moreRead less
Biologically active peptides and proteins from anurans: the relationship between structure and activity. We have identified peptides (from glands of frogs and toads), some of which are amongst the most powerful biologically active compounds in the animal kingdom. The aims of this project are to investigate the relationship between the structure and bioactivity of chosen groups of peptides including pheromones, anticancer and antibiotic peptides, and peptides which inhibit neuronal nitric oxide ....Biologically active peptides and proteins from anurans: the relationship between structure and activity. We have identified peptides (from glands of frogs and toads), some of which are amongst the most powerful biologically active compounds in the animal kingdom. The aims of this project are to investigate the relationship between the structure and bioactivity of chosen groups of peptides including pheromones, anticancer and antibiotic peptides, and peptides which inhibit neuronal nitric oxide synthase. It would be of national benefit if any of these peptides have applied application, e.g. if we can use the sex pheromone of the cane toad to reduce its population, or if we can produce an anticancer active peptide of clinical applicability.Read moreRead less
A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each ....A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each other or adhere to surfaces. The knowledge gained in this project will enable improvements to be made in the efficiency of processes such as those listed above.Read moreRead less
Advanced algorithms for statistical mechanical models. Polymer science, percolation theory and models of magnetism are at the forefront of lattice statistical mechanics and condensed matter theory. Numerical techniques to determine the behaviour of model systems in these areas are predominantly Monte Carlo methods, series generation and analysis, or based on partition function zeroes. New algorithms have been developed for all three methods that are vastly more efficient than their predecessors. ....Advanced algorithms for statistical mechanical models.

Numerical techniques to determine the behaviour of model systems in these areas are predominantly Monte Carlo methods, series generation and analysis, or based on partition function zeroes. New algorithms have been developed for all three methods that are vastly more efficient than their predecessors. Coupled with the availability of dramatically increased computer power, this project takes advantage of a unique position to make dramatic advances in the afore-mentioned research areas. Furthermore, the methods have wider applicability than those mentioned.Read moreRead less
Pushing the Boundaries of Multi-modal Biospectroscopic Microscopies. In order to understand the fundamentals of life processes, diseases, and their treatments, it is essential to probe fundamental changes in molecular processes in cells, tissues and whole organisms. Much of our understanding of these processes has involved the introduction of chemical probes for biospectroscopy, but these have inherent problems because the probe can often change the biochemistry that is being probed. This projec ....Pushing the Boundaries of Multi-modal Biospectroscopic Microscopies. In order to understand the fundamentals of life processes, diseases, and their treatments, it is essential to probe fundamental changes in molecular processes in cells, tissues and whole organisms. Much of our understanding of these processes has involved the introduction of chemical probes for biospectroscopy, but these have inherent problems because the probe can often change the biochemistry that is being probed. This project will push the boundaries of a variety of micro and nano "probe-free" microscopies to provide fundamental insights into these life processes, which could ultimately lead to improvements in the diagnosis, prevention and treatment of diseases.Read moreRead less
Molecular insights into bacterial metal ion homeostasis and toxicity. This project aims to measure bacterial cellular metal concentrations, elucidate mechanisms cells use to adapt to changing extracellular metal concentrations, and reveal the molecular targets of metal toxicity. Metal ions are essential to all forms of life, and half of all proteins use metal ions for cellular chemical processes. However, how cells precisely balance sufficient metal ions for essential cellular chemistry without ....Molecular insights into bacterial metal ion homeostasis and toxicity. This project aims to measure bacterial cellular metal concentrations, elucidate mechanisms cells use to adapt to changing extracellular metal concentrations, and reveal the molecular targets of metal toxicity. Metal ions are essential to all forms of life, and half of all proteins use metal ions for cellular chemical processes. However, how cells precisely balance sufficient metal ions for essential cellular chemistry without accumulating a toxic excess (metal homeostasis) is poorly understood. Discovering the roles of metal ions in bacterial cells will be key to defining the chemical biology of living systems and will provide information essential to understanding how microbes adapt to changing environments.Read moreRead less
