Revealing molecular detail of DNA triplexes to underpin antigene technology. Variations from the classic DNA double helix structure are proposed to play key roles in a range of cellular processes, particularly gene regulation. However, the biological function and therapeutic potential of these unusual DNA structures are poorly explored, since the fundamental molecular details which govern their formation and interactions with cellular machinery are not well described.

Variations from the classic DNA double helix structure are proposed to play key roles in a range of cellular processes, particularly gene regulation. However, the biological function and therapeutic potential of these unusual DNA structures are poorly explored, since the fundamental molecular details which govern their formation and interactions with cellular machinery are not well described. This project aims to develop innovative methods to investigate, and importantly modulate, DNA and RNA triple helix assembly, specificity and molecular interactions. Resulting insights will underpin novel approaches to gene regulation, principally in the context of designing new antibacterial agents to address the antibacterial resistance problem.Read moreRead less
Pluses and minuses of lipid mass spectrometry. This project aims to investigate the structural diversity of lipids. Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of cer ....Pluses and minuses of lipid mass spectrometry. This project aims to investigate the structural diversity of lipids. Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of certain lipids to ionise with a polarity that affords sensitive detection but does not permit detailed structure elucidation. This project will develop advanced instrumentation capable of on-demand polarity switching of ionised lipids such that the detection and interrogation of molecular structure can take place in the optimal charge state.Read moreRead less

Building insights of our largest terrestrial carbon sink: rangelands soils. Rangelands soils represent Australia’s largest carbon sink. Yet, little is known about their potential for carbon sequestration or their vulnerability to climate and environmental change.

Rangelands soils represent Australia’s largest carbon sink. Yet, little is known about their potential for carbon sequestration or their vulnerability to climate and environmental change. This project leverages investments in national terrestrial observation platforms and integrates previous research outputs to develop new methods to measure and build understanding of soil carbon composition and dynamics in rangeland ecosystems. Under a framework that connects detailed measurements and small-scale processes, with machine-learning, data-model assimilation and large-scale next-generation biogeochemical modelling, it’ll allow more accurate predictions of soil carbon change and better decision-making to guide sustainable rangelands management.Read moreRead less

This project aims to develop and apply novel bioanalytical mass spectrometry-based methods and workflows to illuminate the otherwise hidden structural diversity and molecular complexity of the lipidome. The structure of individual lipids define their specific biological functions. A major requirement of analytical methods employed for lipid analysis on a lipidome-wide scale, therefore, is to enable the detailed structural characterisation of the, potentially, tens of thousands of individual molecular lipid species that may be present within a sample of interest. This project will develop and optimise novel, ultraviolet photodissociation-tandem mass spectrometry methods which will be integrated within an automated lipidome analysis workflow, to enable comprehensive global lipidome profiling and to reveal the structural diversity of lipids involved in fundamental cellular signalling processes.Read moreRead less

This project aims to significantly improve the analysis of single cells by mass spectrometry with ultrahigh sensitivity. Molecular differences between cells in large populations can be important in many processes, including cell differentiation and signalling. However, most measurements result in the chemical heterogeneity between cells being masked by the bulk population. Recent discoveries now make it feasible to measure thousands of proteins and small molecules from single cells. This project aims to leverage these breakthroughs to allow heterogeneity to be characterised in single cells with unprecedented molecular detail. This is expected to be important for future biological discovery, as well as disease prediction and drug discovery.Read moreRead less
