Development of Novel Two-dimensional Techniques for Magnetic Resonance In-vivo Spectroscopy. Body chemistry alters with functionality, pain, ageing and disease. These changes can be recorded by magnetic resonance (MR) spectroscopy (MRS) in vivo in a whole body MR scanner. When changes in chemistry can be recorded rapidly, and the individual species assigned, it will be possible to make a definitive diagnosis and in some cases allow the tailoring of treatment on an individual basis. This is curre ....Development of Novel Two-dimensional Techniques for Magnetic Resonance In-vivo Spectroscopy. Body chemistry alters with functionality, pain, ageing and disease. These changes can be recorded by magnetic resonance (MR) spectroscopy (MRS) in vivo in a whole body MR scanner. When changes in chemistry can be recorded rapidly, and the individual species assigned, it will be possible to make a definitive diagnosis and in some cases allow the tailoring of treatment on an individual basis. This is currently hampered by our inability to separate the composite resonances in a one dimensional MR spectrum. Research will allow two dimensional MRS to be implemented and provide detailed chemical information on human organs in vivo. Read moreRead less

The aim of this project is to determine the mechanisms of protein-mediated potassium ion transport across cell membranes. It will combine advanced simulations, structural biology and electrophysiology to describe the detailed molecular processes underscoring calcium-activated potassium channel conduction, gating and inactivation. The expected outcome is an improved description of how ion channels recognise and respond to physiological stimuli to control electrical signalling the body. Our results will provide benefits in the form of basic understanding relevant to ion transport phenomena in biological systems, and atomic-level views of nervous system function to guide future directions in pharmacology.Read moreRead less
Electromechanical controls of membrane transport phenomena. This joint computational-experimental project will explain transport processes carried out by biological membranes under different physiological and pharmacological conditions, to understand the actions of viruses, toxins, antimicrobial peptides and membrane proteins, for novel therapeutics, drug delivery and bio-sensing applications.
The “New” Biochemistry of Polyamines: When Metabolic Pathways Collide. Basic biochemistry and the metabolic regulation of proliferation remain as the fundamental building blocks of knowledge in cell biology that have enabled breakthrough advances in biology and medicine. Polyamines are unique and ubiquitous low-Mr amines that play vital roles in many biological processes, including proliferation, DNA/RNA synthesis, etc. This proposal will mechanistically dissect the "new" biochemistry of polyami ....The “New” Biochemistry of Polyamines: When Metabolic Pathways Collide. Basic biochemistry and the metabolic regulation of proliferation remain as the fundamental building blocks of knowledge in cell biology that have enabled breakthrough advances in biology and medicine. Polyamines are unique and ubiquitous low-Mr amines that play vital roles in many biological processes, including proliferation, DNA/RNA synthesis, etc. This proposal will mechanistically dissect the "new" biochemistry of polyamines, as we have discovered that polyamines are regulated by iron at 2-major levels, involving >10-key polyamine pathway proteins. This proposal represents first-in-field studies specifically designed to dissect mechanisms involved in this relationship. Our Central Hypothesis is that iron regulates polyamine metabolism.Read moreRead less

Crossing quantum-classical boundaries in a single particle. This project is aimed at constructing and observing an individual quantum system that can exhibit chaotic behaviour under controllable conditions. It is a long-sought goal of modern physics that can become reality for the first time in the world, thanks to the unique availability in Australia of the most quantum-coherent single spin ever made and a long history of theoretical advances in the field.

This project is aimed at constructing and observing an individual quantum system that can exhibit chaotic behaviour under controllable conditions. It is a long-sought goal of modern physics that can become reality for the first time in the world, thanks to the unique availability in Australia of the most quantum-coherent single spin ever made and a long history of theoretical advances in the field. Turning a spin into a chaotic system will uncover the true nature of the quantum-classical boundary, and verify whether an underlying classical chaotic dynamics ultimately influences the behaviour of quantum systems. It is expected that the discoveries made will illuminate the path towards the technological exploitation of increasingly complex quantum devices.Read moreRead less
