Activation of invasion in Toxoplasma. Host cell invasion is critical for the establishment and maintenance of infection by the single-celled parasite Toxoplasma gondii, the causative agent of Toxoplasmosis. This project will use the latest molecular techniques to understand how invasion is activated and will define a new set of drug targets to treat Toxoplasmosis and related diseases.
Dynamic regulation of cell signalling scaffolds. This project aims to determine how cells utilise scaffold-type signalling proteins to orchestrate, over time, diverse cellular responses critical for normal development and physiology. The project expects to generate fundamental new knowledge in cell and synthetic biology with broad relevance that will foster establishment of new international linkages and networks. This research should benefit the biotechnology sector by identifying strategies fo ....Dynamic regulation of cell signalling scaffolds. This project aims to determine how cells utilise scaffold-type signalling proteins to orchestrate, over time, diverse cellular responses critical for normal development and physiology. The project expects to generate fundamental new knowledge in cell and synthetic biology with broad relevance that will foster establishment of new international linkages and networks. This research should benefit the biotechnology sector by identifying strategies for engineering scaffolds with desired biological outputs, with applications in areas such as large-scale cell production, immunotherapy, wound healing and regenerative medicine.Read moreRead less

Summary
The molecular basis of endothelial mechanotransduction through TRPV4. This project aims to understand how blood flow dynamics coordinate the plasma membrane localisation and interaction of the transient receptor potential vanilloid 4 (TRPV4), a candidate mechanosensitive ion channel broadly expressed in endothelium with physiological and pathological roles in the cardiovascular system, with other mechanoreceptors and the physiological relevance of these events. Blood flow haemodynamics affect ca ....The molecular basis of endothelial mechanotransduction through TRPV4. This project aims to understand how blood flow dynamics coordinate the plasma membrane localisation and interaction of the transient receptor potential vanilloid 4 (TRPV4), a candidate mechanosensitive ion channel broadly expressed in endothelium with physiological and pathological roles in the cardiovascular system, with other mechanoreceptors and the physiological relevance of these events. Blood flow haemodynamics affect cardiovascular health and morphogenesis. This project will highlight the role of TRPV4 channels in the short- and long-term adaptive responses to shear stress and will also have significant potential for application in future drug discovery.Read moreRead less
How cell shape regulators control cell competition in tissue development. This project aims to determine how cell shape (polarity) regulators affect cell survival in an epithelial tissue. When mutation or wounding perturb cell shape regulators in a tissue cell, signalling pathways are altered that kill the aberrant cells. A surveillance mechanism termed "cell competition" is important to remove the damaged cells. This project will investigate a potential regulator of cell competition, the tyrosi ....How cell shape regulators control cell competition in tissue development. This project aims to determine how cell shape (polarity) regulators affect cell survival in an epithelial tissue. When mutation or wounding perturb cell shape regulators in a tissue cell, signalling pathways are altered that kill the aberrant cells. A surveillance mechanism termed "cell competition" is important to remove the damaged cells. This project will investigate a potential regulator of cell competition, the tyrosine phosphatase PTP61F, in response to perturbation of cell shape regulators, using the vinegar fly, Drosophila, and mammalian systems. This study is expected to reveal biomarkers that can be used to improve organismal fitness to increase productivity or to decrease it for pest control.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.

Single molecule imaging laboratory. Single molecule imaging laboratory: The goal of the project is to establish a single molecule imaging laboratory to close the gap between structural imaging and cellular imaging.

Single molecule imaging laboratory: The goal of the project is to establish a single molecule imaging laboratory to close the gap between structural imaging and cellular imaging. Utilising the expertise of the ARC Centre of Excellence in Advanced Molecular Imaging, the aim of the project is to design, build and apply three microscopes that go beyond the current commercial solutions for single molecule localisation microscopy such as Photo-Activation Localisation Microscopy (PALM) and Stochastic Optical Reconstruction Microscopy (STORM) and perform single molecule imaging: deep inside cells and tissue.The facility will have a fast acquisition rate to monitor highly dynamic molecular events, and improved precision to image molecules and complexes in intact cells with less than or equal to one nanometre resolution. There is currently no comparable imaging facility in the world.Read moreRead less
The importance of exosomal membrane composition in intercellular signaling. Exosomes, microvesicles secreted by cells, are powerful signaling organelles. This project will explore the similarities and differences between the exosomal and host cell membrane. Membrane molecules exclusively present in exosomes may have important signaling implications and can aid in the uptake/fusion of exosomes by/with target cells.
The combined use of proteomics and small molecules for target identification and pathway analysis. This project intends to investigate how a series of new small molecules identified from our research to improve the metabolic effects of insulin. This project will integrate medicinal chemistry with proteomics and metabolic biology to identify the cellular targets and their mechanism of action.
