The proposal seeks to establish an integrated microscopy facility and thus to expand the high-resolution imaging capabilities at Swinburne University of Technology, Peter MacCallum Cancer Institute and the University of Melbourne. The provision of the equipment requested will establish an innovative real-time multi-dimensional multi-photon imaging facility of world class. This facility will be accessed on a cooperative basis by the participants and will be available for collaborative projects with other Australian institutions and industry. The requested equipment will be used in conjunction with existing femtosecond laser and lifetime imaging systems installed in the research laboratories of the participating institutions. The facility will enable real-time investigations of biomolecular processes and the development of novel biomedical imaging techniques as well as the state-of-the-art nanophotonic devices such as nano-tweezers and nano compact disks.Read moreRead less
Molecular Mechanisms of Biochemical Regulation: Neutron and X-ray Scattering Studies. 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.

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
Molecular mechanisms of two-component signal transduction in bacteria. The focus of this research is on the protein complexes that transmit signals in bacteria to elicit the desired responses to environmental stimuli. Like many dynamic processes in cells, signaling requires proteins that are flexible and hence resistant to high-resolution structural analysis using crystallography. We will make use of new research infrastructure at the Australian synchrotron and OPAL research reactor to overcom ....Molecular mechanisms of two-component signal transduction in bacteria. The focus of this research is on the protein complexes that transmit signals in bacteria to elicit the desired responses to environmental stimuli. Like many dynamic processes in cells, signaling requires proteins that are flexible and hence resistant to high-resolution structural analysis using crystallography. We will make use of new research infrastructure at the Australian synchrotron and OPAL research reactor to overcome the challenges of flexibility in these systems. The proteins we will study are not found in humans, and hence our research will provide important structural data on potential targets for the design of novel antibiotics to fight bacterial infection.Read moreRead less

Summary
High-resolution imaging of live cells and tissue. Understanding the machinery of life and developing technologies that support life's processes requires biological and physical scientists and engineers to monitor molecular events in living systems. The aim is to take advantage of very recent developments in light microscopy to enable the non-invasive imaging of live cells and tissue at a previously unreachable level of detail. The instruments will form the nucleus of a new imaging facility. Sign ....High-resolution imaging of live cells and tissue. Understanding the machinery of life and developing technologies that support life's processes requires biological and physical scientists and engineers to monitor molecular events in living systems. The aim is to take advantage of very recent developments in light microscopy to enable the non-invasive imaging of live cells and tissue at a previously unreachable level of detail. The instruments will form the nucleus of a new imaging facility. Significant advances in research areas including vascular research, cancer, immunology, cell and molecular biology, functional genomics, biotechnology, nanotechnology and material engineering will be of major benefit both nationally and globally.Read moreRead less
Hierarchical modeling of protein interactions. Protein interactions play a central role in function and structural organization of cells. Their elucidation is essential for a better understanding of many cellular processes from signal transduction to enzyme inhibition. The aim of this project is to utilize the unprecedented powers of current supercomputers in developing a hierarchical model of protein interactions.

Protein interactions play a central role in function and structural organization of cells. Their elucidation is essential for a better understanding of many cellular processes from signal transduction to enzyme inhibition. The aim of this project is to utilize the unprecedented powers of current supercomputers in developing a hierarchical model of protein interactions. The method combines Brownian dynamics at large distances and long time scales with molecular dynamics at small distances and shorter times. Applications to both membrane proteins (blocking of ion channels by toxins and drugs) and globular proteins (ligand binding to receptors and protein association) will be considered.Read moreRead less
A hierarchical quantum mechanical and classical simulation of biological ion channels. I aim to develop a methodology incorporating molecular quantum

applied practically to large macromolecular systems, thus relating

properties. Specifically, I will apply this methodology to study ion
channels in which the challenge is to relate electronic and atomic
structure to the conductance properties of the channel. Accurately
determining these relationships provides a pathway to developing cures
for many neurological, cardiac, and muscular diseases.

Surface Forces in Aqueous Electrolytes. This project studies the force between two nearby colloidal particles or macromolecules in aqueous electrolyte solutions. Although such forces control the approach and binding of particles in electrolytes and hence have large practical significance they are poorly known. In recent work I established a rigorous scheme for calculation of the electrostatic contribution to the force and proved its feasibility. In order to realise practical applications, such a ....Surface Forces in Aqueous Electrolytes. This project studies the force between two nearby colloidal particles or macromolecules in aqueous electrolyte solutions. Although such forces control the approach and binding of particles in electrolytes and hence have large practical significance they are poorly known. In recent work I established a rigorous scheme for calculation of the electrostatic contribution to the force and proved its feasibility. In order to realise practical applications, such as in drug design, we must know the mean force between an ion and a surface or functional surface group. Here I propose to perform the required simulations and explore the analytical simplifications.Read moreRead less
