Summary
Formation of the osteocyte network in bone matrix. The formation of new bone, which occurs throughout life for bone renewal and acutely after fractures, entraps a network of cells that can detect micro-damage and direct repair mechanisms. Mathematical and computational methods will be used to understand how this network can lead to a self-detecting and self-repairing biomaterial.
Keeping forces local for epithelial homeostasis. This project probes how epithelial cells use mechanical forces to communicate with one another in biological life. It tests the novel concept that negative feedback is a critical, hitherto unappreciated dimension in mechanical communication, which acts to ensure proportionate responses for homeostasis. It will generate fundamental new knowledge in biology using an innovative combination of cellular and biophysical experiments and physical theory. ....Keeping forces local for epithelial homeostasis. This project probes how epithelial cells use mechanical forces to communicate with one another in biological life. It tests the novel concept that negative feedback is a critical, hitherto unappreciated dimension in mechanical communication, which acts to ensure proportionate responses for homeostasis. It will generate fundamental new knowledge in biology using an innovative combination of cellular and biophysical experiments and physical theory. The expected outcomes are fundamental new knowledge, interdisciplinary training for young scientists, new national research capacity and growing international collaborations. It will benefit Australia by enhancing its scientific world linkage, status in scientific leadership and research capacity.Read moreRead less
The discovery and characterisation of novel protein regulators of blood cell formation. All of the mature blood cells in the human body are derived from a common ancestor cell type known as a stem cell. Our proposed studies will enhance our knowledge of how functional, mature blood cells are formed from stem cells and how dysregulation of these normally tightly controlled pathways can give rise to severe blood diseases.

Summary
Human cytomegalovirus (HCMV) is a human pathogen that infects over 60% of the adult population, and is a major cause of birth defects causing permanent hearing and vision loss, and mental retardation. To investigate the critical involvement of host epigenetic factors, I will study the roles of sirtuins during HCMV infection. Through proteomic, genomic, microscopy, and bioinformatic techniques, I aim to further our understanding of viral pathogenesis, towards developing novel therapies.
Decision-making modules in protein interaction networks. This project aims to discover how cells use proteins to make decisions. This is important for all living things, which must react to stimuli to grow, adapt, defend themselves and to die. The project’s anticipated outcome is the systems-level identification of decision-making modules in an intracellular network. Its focus is on the smallest possible modules, which contain a decision-making protein with two modifications that control protein ....Decision-making modules in protein interaction networks. This project aims to discover how cells use proteins to make decisions. This is important for all living things, which must react to stimuli to grow, adapt, defend themselves and to die. The project’s anticipated outcome is the systems-level identification of decision-making modules in an intracellular network. Its focus is on the smallest possible modules, which contain a decision-making protein with two modifications that control protein-proteins interactions. It will investigate two recurrent decision-making modules. The expected benefits of the project include new means to decipher biological complexity, and targets to modulate biosystems by genome editing or with drugs.Read moreRead less
The role and regulation of protein methylation: a study using the recently developed methylation network of yeast. Tiny changes to proteins, such as methylation, can alter the way they interact with other proteins. This project will investigate the dynamics of protein methylation during the life of the yeast cell. The project results will be of long term relevance to situations where we may want to stop cells dividing, such as cancer or infectious disease.
The effect of methylation and phosphorylation on ribosome function. This project aims to discover how cells regulate ribosome function and selectivity, by modifying their ribosomal proteins. This affects protein synthesis, a process which is central to the growth of all living things. Expected outcomes include new knowledge on the regulation of protein synthesis, improved techniques for the study of this process and an enhanced capacity for international collaboration.

This affects protein synthesis, a process which is central to the growth of all living things. Expected outcomes include new knowledge on the regulation of protein synthesis, improved techniques for the study of this process and an enhanced capacity for international collaboration. New avenues for the artificial regulation of the ribosome may also emerge, relevant to synthetic biology and the engineering of industrial yeasts. The project should provide significant new findings for the research community, generate research citations and contribute to a highly skilled workforce by the training of staff and students.Read moreRead less
Does phosphorylation regulate the methylation of proteins? . The interaction of proteins is a fundamental requirement of life. Tiny switches on proteins affect how they interact but little is known about how these are controlled. This project will study the complex interplay between two types of switches; one is expected to control the other. This will provide new insights into how the cell functions.

Protein network regulation: A systems-level analysis of methylation. The systems-level analysis of protein-protein interaction networks is a vital new framework for exploring protein complex formation. However key studies into the dynamics of these networks are being precluded by a lack of broad-scale data on interactions mediated by post-translational modifications, which are known regulators of protein-protein interactions. To solve this problem, this project aims to conduct an organism-wide s ....Protein network regulation: A systems-level analysis of methylation. The systems-level analysis of protein-protein interaction networks is a vital new framework for exploring protein complex formation. However key studies into the dynamics of these networks are being precluded by a lack of broad-scale data on interactions mediated by post-translational modifications, which are known regulators of protein-protein interactions. To solve this problem, this project aims to conduct an organism-wide survey of interactions mediated by an important class of post-translational modification, methylation, using an innovative mass spectrometry-based workflow. This project aims to produce fundamental new insights into the mechanisms underlying protein-protein interaction network dynamics, and into how protein complexes are formed.Read moreRead less

Summary
Drug combinations in chemotherapy hold promise for more effective treatments and for overcoming drug resistance, but the search for effective combinations is challenging. The combination therapy R-CHOP is often curative for Diffuse Large B-cell Lymphoma (DLBCL). Both cellular drug interactions and evolutionary drug interactions will be quantified in DLBCL cells, to understand the defining features of effective combinations and guide the future rational design of combinations.
