This project aims to create micro-optics for astronomical and bio medical applications by 3D sculpturing them out of crystals by ultra-short pulse lasers. This project will introduce a new 3D fabrication approach of optical probes which have self-aligned micro-optical elements and optical fibres for a wide spectral range and with high quality optical surfaces. Expected outcomes of this project include building new capabilities in micro-optical probes for industrial environments, establishing new solutions for international astronomy partners, and developing new techniques to image through optical fibres. This should provide significant benefits by improving astronomical instrumentation and also lead to less invasive endoscopy.Read moreRead less
Regulation of lung immune-epithelial networks sensing environmental change. This study aims to uncover how lung epithelial cells engage with immune cells and determine their cellular and molecular wiring to ensure homeostatic maintenance and essential repair processes of lung tissues. Maintenance of lung epithelial-immune networks is essential to maintain normal lung tissue structure and function, and to induce immune responses to protect against microbial challenges or inhaled potentially toxic ....Regulation of lung immune-epithelial networks sensing environmental change. This study aims to uncover how lung epithelial cells engage with immune cells and determine their cellular and molecular wiring to ensure homeostatic maintenance and essential repair processes of lung tissues. Maintenance of lung epithelial-immune networks is essential to maintain normal lung tissue structure and function, and to induce immune responses to protect against microbial challenges or inhaled potentially toxic substances. Understanding this molecular program of epithelial-immune cell-mediated sensing/repair will be essential to understand how tissue-repair processes can be driven in the lung, an organ critical for respiration and thus life.Read moreRead less
Understanding the T cell repertoire in health and disease. Immune recognition of viruses usually involves a large number of different 'killer T cells' that kill cells infected by virus. However, during prolonged infection or in the elderly the number of different killer T cells that recognise the virus is greatly reduced. This reduction in the diversity of the immune response allows the virus to avoid immune recognition, and leads to more severe infection. We aim to understand how diversity is ....Understanding the T cell repertoire in health and disease. Immune recognition of viruses usually involves a large number of different 'killer T cells' that kill cells infected by virus. However, during prolonged infection or in the elderly the number of different killer T cells that recognise the virus is greatly reduced. This reduction in the diversity of the immune response allows the virus to avoid immune recognition, and leads to more severe infection. We aim to understand how diversity is generated in the immune response, and how it becomes narrowed with age or prolonged infection. This information can be used to design vaccines for persistent infections such as HIV, and to improve immune control of infection in the elderly.Read moreRead less
The macrophage nucleus - its form and function during migration in vivo. As cells migrate through tissues, they encounter complex, 3-dimensional environments that provide cues to guide them and present obstacles in their path. This project focuses on macrophages, a large immune cell capable of both amoeboid and mesenchymal modes of migration. The nucleus is the largest organelle and its bulk and stiffness must be managed as migrating cells travel through constrictions. The project uses specialis ....The macrophage nucleus - its form and function during migration in vivo. As cells migrate through tissues, they encounter complex, 3-dimensional environments that provide cues to guide them and present obstacles in their path. This project focuses on macrophages, a large immune cell capable of both amoeboid and mesenchymal modes of migration. The nucleus is the largest organelle and its bulk and stiffness must be managed as migrating cells travel through constrictions. The project uses specialised high-end microscopy and genetic methods to examine how the nucleus of migrating zebrafish macrophages deforms, repositions and is restructured during migration in living tissues, and how this influences macrophage locomotion. The goal is to provide fundamental insights into the cell biology of macrophage migration.Read moreRead less
Nuclear plasticity during neutrophil migration and function. This project aims to discover how nuclear shape affects neutrophil function. Cell migration needs overall cellular plasticity and plasticity of internal structures such as the nucleus. The neutrophil, one of the most peripatetic cell types, has a specialised lobulated nucleus, thought to facilitate its mobility and function. Using zebrafish reporter lines that concurrently display the nucleus and cytoplasm, this project will display th ....Nuclear plasticity during neutrophil migration and function. This project aims to discover how nuclear shape affects neutrophil function. Cell migration needs overall cellular plasticity and plasticity of internal structures such as the nucleus. The neutrophil, one of the most peripatetic cell types, has a specialised lobulated nucleus, thought to facilitate its mobility and function. Using zebrafish reporter lines that concurrently display the nucleus and cytoplasm, this project will display the dynamic plasticity of neutrophil nuclei during neutrophil migration and function in vivo. This project seeks to use the spatiotemporal resolution of a lattice light sheet microscope to examine this further, and explore its effect on neutrophil function. The project seeks to establish morphological and mechanical principles applying not just to neutrophils, but to all migratory cell types.Read moreRead less
In-vivo detection of airway injury and disease using phase contrast X-ray velocimetry. Currently diagnosis of lung disease, a major cause of death in humans, is based on clinical symptoms that do not usually manifest until the disease is well advanced. This project will develop a novel imaging technique, X-ray velocimetry, to detect changes in tissue before symptoms arise, potentially leading to strategies for managing lung diseases.
Elucidating the post-transcriptional regulation of mast cell proteases. Mast cells (MCs) are immune cells that protect against pathogens but may induce deleterious inflammation. MC function is mediated by specific proteases that are pre-formed and stored in granules. These proteases have unique yet poorly understood mechanisms of regulation. The aim of the project is to use a novel suite of molecular tools and genetically modified mice to identify the critical regions of transcripts that post-tr ....Elucidating the post-transcriptional regulation of mast cell proteases. Mast cells (MCs) are immune cells that protect against pathogens but may induce deleterious inflammation. MC function is mediated by specific proteases that are pre-formed and stored in granules. These proteases have unique yet poorly understood mechanisms of regulation. The aim of the project is to use a novel suite of molecular tools and genetically modified mice to identify the critical regions of transcripts that post-transcriptionally regulate the production and storage of these proteins. The project aims to identify the RNA binding proteins, microRNAs and other novel factors that also regulate them. This is expected to elucidate the post-transcriptional mechanisms of regulation of MC proteases.Read moreRead less
The role of the protease inhibitor Serpinb9 in antigen cross-presentation by dendritic cells. This project will provide fundamental new insights into antigen cross-presentation, a crucial facet of the immune system's response to viral infection or neoplastic cells. It will also provide a basis for future studies into mechanisms of immune tolerance and enhance our understanding of autoimmune disease.
Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal coopera ....Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal cooperation paved the way for the origin of parasitism. The second key outcome will be to identify the precise molecular mechanism that allowed parasitism to arise. This will benefit us through understanding the origins of important diseases such as human malaria and related infections of livestock and wildlife.

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.

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
