Integrating rifts and swell in the mathematics of ice shelf disintegration. Antarctic ice-shelf disintegrations have the alarming potential to cause rapid sea level rise, through accelerated discharge of the Antarctic Ice Sheet and initiating runaway Ice Sheet destabilisations. The project aims to develop a mathematical model of swell-induced ice-shelf vibrations in a coupled ocean–shelf 3D framework, focusing on interactions between vibrations and the rift networks that characterise outer shelf ....Integrating rifts and swell in the mathematics of ice shelf disintegration. Antarctic ice-shelf disintegrations have the alarming potential to cause rapid sea level rise, through accelerated discharge of the Antarctic Ice Sheet and initiating runaway Ice Sheet destabilisations. The project aims to develop a mathematical model of swell-induced ice-shelf vibrations in a coupled ocean–shelf 3D framework, focusing on interactions between vibrations and the rift networks that characterise outer shelf margins before disintegration. Accurate, efficient solutions will be developed by fusing powerful approximation theories, and validated by numerical solutions. The model will be combined with state-of-the-art data to predict trends in Antarctica’s remaining ice shelves and indicate potential future disintegrations.Read moreRead less

In the macroscopic world, containers are used to hold, provide physical protection, or create a modified environment for their contents. This project will result in the synthesis of novel molecular container materials that provide decorated internal surfaces capable of selectively binding chemical species. In addition to the breakthrough scientific benefits of establishing the fundamentals of these systems, the binding of chemicals, which are environmental contaminants, will provide the grounding for applications that will contribute to the national priority of 'Frontier technologies'. Furthermore, this research will lead to the training of the next generation of Australian scientists by quality international researchers.Read moreRead less
Unconventional antennas from macro- to nano-scales. This research project will develop unconventional radio-frequency antennas for tomorrow's miniaturised multi-function wireless communication systems. It will also extend the principles to resonant nano-structures or 'optical antennas' which offer new perspectives in sensing physics, with the possibility of single molecule detection and identification.
Using natural products to inspire discoveries in synthesis and biosynthesis. This project aims to understand the organic chemistry that occurs in the biosynthesis of unusual antibiotic natural products by marine microorganisms. In an interdisciplinary approach, proposed biosynthetic intermediates will be synthesised and screened against newly isolated enzymes from the microorganisms of interest. This will allow the elucidation of biosynthetic pathways, and aid the discovery of new chemoenzymatic ....Using natural products to inspire discoveries in synthesis and biosynthesis. This project aims to understand the organic chemistry that occurs in the biosynthesis of unusual antibiotic natural products by marine microorganisms. In an interdisciplinary approach, proposed biosynthetic intermediates will be synthesised and screened against newly isolated enzymes from the microorganisms of interest. This will allow the elucidation of biosynthetic pathways, and aid the discovery of new chemoenzymatic reactivity that may be broadly useful in organic synthesis. Non-enzymatic, predisposed organic reactions will also be uncovered during the project. The benefit of this project will be an improvement in our ability to synthesise potential antibiotics using a combined synthetic organic and chemoenzymatic approach. This could lead to useful new antibiotics in the future.Read moreRead less
Artificial photosynthesis for solar fuel production. We aim to realise an artificial system that converts solar energy to hydrogen (artificial photosynthesis). The resulting device will be able to 'split' water into oxygen and hydrogen, whereas hydrogen can be further converted into electricity or heat (combustion).

Deciphering Electron Transfer Pathways in Bacteria. Enzyme catalysed oxidation reactions are key players in the production of naturally occurring biologically active molecules. These processes are tightly regulated by their electron transfer partners. This project aims to characterise new electron transfer ferredoxin proteins from a metabolically diverse bacterium.

Enzyme catalysed oxidation reactions are key players in the production of naturally occurring biologically active molecules. These processes are tightly regulated by their electron transfer partners. This project aims to characterise new electron transfer ferredoxin proteins from a metabolically diverse bacterium. These ferredoxins, important in many bacteria, contain different non-cysteine amino acids in their iron-sulfur cluster binding motifs and are poorly defined. The outcomes will advance understandings of electron transfer, a fundamental process. This will allow strategies to combat human and plant pathogens and unlock the potential of these systems as biocatalysts for the green chemical synthesis of complex and valuable chemicals.Read moreRead less
