Intermolecular interactions revisited-Flaws in the fabric and applications to lower-dimensional structures. This project aims to capitalise on recent developments, that have shown that previously accepted theories are deeply flawed, in various applications in fundamental physics and in unsolved problems in biology that involve electromagnetic fields. Interactions driven
by electromagnetic fluctuation forces, and real photon exchange, between molecules will be investigated.

This project aims to capitalise on recent developments, that have shown that previously accepted theories are deeply flawed, in various applications in fundamental physics and in unsolved problems in biology that involve electromagnetic fields. Interactions driven
by electromagnetic fluctuation forces, and real photon exchange, between molecules will be investigated. The project will investigate how dispersion interactions change in mesoscopic pores, in electrolytes, and at finite temperatures. Applications involve
catalysis, molecular formation, and quantum logic. The project also aims to develop a unified theory for energy and charge transfer, relevant for photosynthesis and the way biological molecules transfer information.Read moreRead less
From structures to systems: A hierachical approach to understanding sub-cellular components. This program will dramatically extend the range of biomolecular systems that can be modelled with near atomistic precision. It will provide a better understanding of the structure and function of proteins involved in the regulation of membrane fusion and fission as well as shedding light on the assembly of large-scale protein-protein and protein-membrane complexes in general. The work will help place Au ....From structures to systems: A hierachical approach to understanding sub-cellular components. This program will dramatically extend the range of biomolecular systems that can be modelled with near atomistic precision. It will provide a better understanding of the structure and function of proteins involved in the regulation of membrane fusion and fission as well as shedding light on the assembly of large-scale protein-protein and protein-membrane complexes in general. The work will help place Australia at the forefront of developing simulation techniques in biomolecular systems, which are widely used within the chemical and pharmaceutical industries for modelling processes ranging from protein-drug interactions to the phase behaviour of lipids and surfactants.

A rational approach to a high-resolution structure of the multidrug transporter EmrE. Membrane proteins form only 0.3% of the available protein structures in the protein data bank (PDB), yet 30% of the proteins in the human genome and 50% of human drug targets are membrane proteins. Multidrug transporters are membrane proteins responsible for antibiotic resistance in humans. A high-resolution structure of a multidrug resistance protein, together with comprehensive biochemical characterization, w ....A rational approach to a high-resolution structure of the multidrug transporter EmrE. Membrane proteins form only 0.3% of the available protein structures in the protein data bank (PDB), yet 30% of the proteins in the human genome and 50% of human drug targets are membrane proteins. Multidrug transporters are membrane proteins responsible for antibiotic resistance in humans. A high-resolution structure of a multidrug resistance protein, together with comprehensive biochemical characterization, would enable a detailed understanding of how these protein functions. Potentially it could also aid in the development of specific inhibitors that would prevent EmrE (and perhaps other similar proteins) from carry out its harmful mission. Read moreRead less
Functional Dissection of the Bacterial Replisome. We now have the complete sequences of genes in humans and many other organisms, but we know much less about how the protein products of the genes communicate with each other to create and grow cells. Australia has recently invested heavily in state-of-the-art instruments that can be used to tackle these problems. This project will involve close interaction of four laboratories to use new instruments to determine how a large assembly of proteins i ....Functional Dissection of the Bacterial Replisome. We now have the complete sequences of genes in humans and many other organisms, but we know much less about how the protein products of the genes communicate with each other to create and grow cells. Australia has recently invested heavily in state-of-the-art instruments that can be used to tackle these problems. This project will involve close interaction of four laboratories to use new instruments to determine how a large assembly of proteins interact in a biological machine that makes DNA. This process occurs in similar ways in all organisms, and is essential for life. Understanding how DNA is made will help scientists to develop new antibacterial drugs, and learn how to make practical use of molecular machines that imitate biology.Read moreRead less
Self organization in (bio)molecular systems: Simulating the folding and aggregation of peptides, proteins and lipids. Molecular self-assembly is a basic property of living systems. Most proteins fold spontaneously and then further self-organize into functional complexes, effectively biological machines. Understanding how this occurs is a fundamental theoretical challenge with widespread application. Work will focus on developing methodology to simulate, computationally, the folding and aggrega ....Self organization in (bio)molecular systems: Simulating the folding and aggregation of peptides, proteins and lipids. Molecular self-assembly is a basic property of living systems. Most proteins fold spontaneously and then further self-organize into functional complexes, effectively biological machines. Understanding how this occurs is a fundamental theoretical challenge with widespread application. Work will focus on developing methodology to simulate, computationally, the folding and aggregation of peptides, proteins, and lipids. The aim is to accurately predict the structures of small peptides in solution and to refine crude models of larger molecules (complexes). This will facilitate the development of peptide based therapeutics and is essential in exploiting the growing volume of genetic information in biology and medicine.Read moreRead less
Electro-active and migratory peptides in lipid bilayers: NMR and biophysical studies. All living things are characterized by the separation of inner space from the surrounding medium by a self-assembling membrane. Selective entry and exit of water, ions and solutes is a defining feature of each type of cell. Some proteins sense the voltage difference across the cell membrane and open or close in response to voltage changes. Others, like bacterial toxins assemble in the membrane as pores, while o ....Electro-active and migratory peptides in lipid bilayers: NMR and biophysical studies. All living things are characterized by the separation of inner space from the surrounding medium by a self-assembling membrane. Selective entry and exit of water, ions and solutes is a defining feature of each type of cell. Some proteins sense the voltage difference across the cell membrane and open or close in response to voltage changes. Others, like bacterial toxins assemble in the membrane as pores, while other peptides migrate across the membrane piggy-backing their peptide cargo. The aim is to understand the molecular mechanisms in examples of these membrane-active peptides and proteins with a view to enabling rational intervention into their operation in situ in normal and disease states.Read moreRead less

This project will develop and use novel neutron and x-ray scattering methods to study the molecular mechanisms by which nature regulates biochemical processes. Healthy function requires cells to tightly control and coordinate a myriad of molecular activities. My research focuses on a set of interdependent molecular networks inside cells whose behavior is controlled by the so-called 'second messengers' that translate external signals into the right cellular responses. The proposed experiments will provide a unique structural framework by which we can understand how these signals are transmitted. Such knowledge is an important foundation for advances in biomedical research and biotechnology applications.Read moreRead less
