Cracking post-translational modification codes in high molecular definition. This project aims to markedly improve the analysis of post-translational modifications (PTM) via intact protein mass spectrometry. Differences in the PTM forms of a protein (modforms) can be crucial in many physiological and metabolic processes. However, current conventional methods cannot accurately separate nor fully assign most protein modforms. A recent discovery has resulted in the ability to separate whole protein ....Cracking post-translational modification codes in high molecular definition. This project aims to markedly improve the analysis of post-translational modifications (PTM) via intact protein mass spectrometry. Differences in the PTM forms of a protein (modforms) can be crucial in many physiological and metabolic processes. However, current conventional methods cannot accurately separate nor fully assign most protein modforms. A recent discovery has resulted in the ability to separate whole protein ions that have the same mass, charge, and collision cross section, but subtly different charge sites. This project aims to leverage this breakthrough by developing novel approaches for separating intact protein modforms and mapping PTM sites. This is expected to be important for future biological discovery.Read moreRead less
Imaging metal homeostasis in the ageing brain. This fellowship aims to deliver new tools to visualise how changes to blood vessels during ageing effect the amount and distribution of metal ions in brain cells in animal models. This will be a significant advance as current methods cannot image these parameters. Metal ions are essential for brain function, but the effects of ageing on metal ions within brain cells is largely unknown. The results are expected to associate brain-blood vessel permeab ....Imaging metal homeostasis in the ageing brain. This fellowship aims to deliver new tools to visualise how changes to blood vessels during ageing effect the amount and distribution of metal ions in brain cells in animal models. This will be a significant advance as current methods cannot image these parameters. Metal ions are essential for brain function, but the effects of ageing on metal ions within brain cells is largely unknown. The results are expected to associate brain-blood vessel permeability with changes to metal ion content during ageing. The methods developed, and the fundamental new knowledge they reveal will benefit national and international neuroscientists seeking to elucidate the fundamental neurobiology of metal ions with respect to maintaining healthy brain function.Read moreRead less
Mapping dynamic lipid biochemistry with high spatial and molecular detail. Lipids are a complex and underappreciated family of molecules playing important roles in all of our tissues and cells. Yet, our fundamental knowledge of lipids is limited by current technology. This project aims to develop an innovative mass spectrometry imaging platform allowing lipid biochemistry to be visualised at a level of detail not before possible.

Lipids are a complex and underappreciated family of molecules playing important roles in all of our tissues and cells. Yet, our fundamental knowledge of lipids is limited by current technology. This project aims to develop an innovative mass spectrometry imaging platform allowing lipid biochemistry to be visualised at a level of detail not before possible. This will push boundaries in molecular imaging technology and is expected to provide new fundamental knowledge about the structure, function and distributions of lipids in tissues and cells. Significant benefits should include providing new tools to unravel the functions and modifications of lipids in biology, that can be extended to many other research and industrial applications.

Natural iron fertilisation of oceans around Australia: linking terrestrial dust, marine biogeochemistry and climate. Oceans play a vital role in Earth’s climate through the control of atmospheric carbon dioxide. An important component of this system is the iron cycle, in which iron-rich dust is transported from the land via atmosphere to ocean; iron is a key micronutrient for marine phytoplankton, the scarcity of which limits essential biogeochemical processes and ocean fertility. This project w ....Natural iron fertilisation of oceans around Australia: linking terrestrial dust, marine biogeochemistry and climate. Oceans play a vital role in Earth’s climate through the control of atmospheric carbon dioxide. An important component of this system is the iron cycle, in which iron-rich dust is transported from the land via atmosphere to ocean; iron is a key micronutrient for marine phytoplankton, the scarcity of which limits essential biogeochemical processes and ocean fertility. This project will conduct an integrated oceanographic and atmospheric observational program for trace elements in the oceans around Australia. This will provide the critical information on iron supplied from atmospheric dust for ocean productivity and marine ecosystem health, providing the science for predicting a key factor in the future impact of the oceans on climate.Read moreRead less
Solid-state light sources for bio-imaging and microfluidics. Solid state light sources are the light sources of the 21st century. This project will allow us to find new ways of bioimaging in living organisms applicable to diagnosing disease, and for microfluidic chip based portable instruments for on-site and point-of-care analysis in medical diagnostics, environmental monitoring, and manufacturing processes.
New strategies for highly sensitive chemical detection based on luminescent ruthenium and iridium complexes. Chemical reactions that emit tiny quantities of light, not even visible to the naked eye, can be used to detect the biomarkers of disease or traces of chemical or biological weapons in a terrorist attack. This project creates a new generation of reagents for this remarkably sensitive mode of detection for these and other important applications.

Identifying novel salinity tolerance mechanisms by spatial and temporal analysis of lipids in barley. Agrifood production faces the dual challenges of an increasing world population and the threats of abiotic stresses arising from climate change and the erosion of arable land. Cereals, the major food crops, are poorly adapted to tolerate most abiotic stresses, including salinity.

Agrifood production faces the dual challenges of an increasing world population and the threats of abiotic stresses arising from climate change and the erosion of arable land. Cereals, the major food crops, are poorly adapted to tolerate most abiotic stresses, including salinity. This project applies new technologies investigating spatial and temporal biochemical mechanisms a model cereal, Hordeum vulgare (barley), utilises to adapt and tolerate salinity. The aims are to investigate the role of specifically plasma membrane lipids modulating either signalling pathways or membrane fluidity that impacts on adaptation during salinity. The results will provide new leads for the development of cereal germplasm with increased salt tolerance.Read moreRead less
