The control of chromosome division during female meiosis. Mammalian eggs are stored life-long and finally mature in the hours before ovulation. This project examines how the chromosomes in the egg are separated properly so as to produce a mature egg capable of being fertilized by a sperm. Often in eggs chromosome division is imprecisely executed, and this project will help us understand why this occurs.
Single molecule intracellular intravital imaging of actin dynamics. The project intends to develop imaging technology to visualise fundamental processes in cells within a living animal. The focus will be on the actin cytoskeleton, a dynamic macromolecular machine involved in key cellular processes including cell structure, mobility and division. It is exquisitely sensitive to environmental perturbations, requiring it to be studied in cells in living tissue. The project aims to extend the resolut ....Single molecule intracellular intravital imaging of actin dynamics. The project intends to develop imaging technology to visualise fundamental processes in cells within a living animal. The focus will be on the actin cytoskeleton, a dynamic macromolecular machine involved in key cellular processes including cell structure, mobility and division. It is exquisitely sensitive to environmental perturbations, requiring it to be studied in cells in living tissue. The project aims to extend the resolution of live imaging to the single molecule to understand the dynamics of actin assembly with implications for cellular processes that are hijacked in diseases. It also aims to provide a novel assay that may enable testing of the impact of drugs on cellular processes in real time.Read moreRead less
The role of copper in the early ubiquitination pathway. This project aims to explore the role of copper in ageing and protein turnover. The removal of damaged or excess proteins is achieved by ubiquitin-tagging in all kingdoms of life. It has recently been observed that one of the earliest steps of this process appears to be driven by copper. This project aims to elaborate the precise biochemical mechanisms by which copper regulates this important tagging and protein turnover system.

The removal of damaged or excess proteins is achieved by ubiquitin-tagging in all kingdoms of life. It has recently been observed that one of the earliest steps of this process appears to be driven by copper. This project aims to elaborate the precise biochemical mechanisms by which copper regulates this important tagging and protein turnover system. It proposes to characterise the structure and function of a newly identified copper-dependent form of cell enzyme which could be involved in amplifying ubiquitin-tagged protein breakdown. Copper is essential for life in all domains. Identifying copper as a major regulator in protein clearance is important in understanding this fundamental biological machinery.Read moreRead less
A molecular timer for inflammation and cell death. This project aims to improve our understanding of the timely function of the immune system. Most processes fundamental to life rely on the timely execution of cellular functions. One biological system in which timing is paramount is the immune system. Organismal health relies upon this front-line defence system for rapidly detecting invading microbes and inducing an appropriate, and timely, antimicrobial response to clear infection. We do not cu ....A molecular timer for inflammation and cell death. This project aims to improve our understanding of the timely function of the immune system. Most processes fundamental to life rely on the timely execution of cellular functions. One biological system in which timing is paramount is the immune system. Organismal health relies upon this front-line defence system for rapidly detecting invading microbes and inducing an appropriate, and timely, antimicrobial response to clear infection. We do not currently understand how immune responses are temporally coordinated. This proposal aims to address this key knowledge gap by characterising a novel molecular timer that dictates the co-ordinated timing of immune responses and immune cell death. These studies may yield fundamental insight into mammalian anti-microbial mechanisms.Read moreRead less
Understanding how mitochondria divide. This project aims to investigate the molecular mechanism by which mitochondria divide. Mitochondria are the powerhouse within our cells, and they grow and divide in our cells to ensure that they are transferred to daughter cells and also so that older mitochondria can be turned over. The project plans to build on the discovery of mitochondrial membrane proteins that are involved in fission. The results of the project could provide fundamental new knowledge ....Understanding how mitochondria divide. This project aims to investigate the molecular mechanism by which mitochondria divide.

Characterising the lipid droplet-mitochondria proteome. This project aims to determine the mechanisms by which the mitochondria and lipid droplets associate, and how this interaction influences lipid metabolism. Both critical for survival, lipid droplets are the bulk energy store in cells and the mitochondria break down this lipid to generate energy. It is anticipated that this project will identify the proteins that are critical for regulating contact between these organelles and the consequenc ....Characterising the lipid droplet-mitochondria proteome. This project aims to determine the mechanisms by which the mitochondria and lipid droplets associate, and how this interaction influences lipid metabolism. Both critical for survival, lipid droplets are the bulk energy store in cells and the mitochondria break down this lipid to generate energy. It is anticipated that this project will identify the proteins that are critical for regulating contact between these organelles and the consequences if this process becomes dysregulated. The project expects to provide fundamental new knowledge in understanding how organelles interact and how lipid metabolism is regulated. This knowledge has applications for the primary industries and biotechnology sector.Read moreRead less
The rational design and construction of new genetic circuits for applications in synthetic biology. By designing, building and testing new gene control modules, this project will gain an understanding of the design principles required for the construction of biological circuits with predictable and controllable behaviour. The ability to build such circuits will have significant economic benefit in areas such as metabolic engineering and biomedicine.

Summary
Investigation and development of biological anti-adhesive coatings. Lubricin is a biological anti-adhesive protein that is found in mammalian joints. This project will investigate the properties and action of Lubricin and develop novel anti-adhesive coating technologies to eliminate problems associated with non-specific binding of biomolecules in microfluidic and biosensor applications.
Tuning Molecular Translocaton by Close-Field Electroporation. This project aims to determine the underlying mechanisms by which DNA and other molecules are able to migrate across the cell membrane in response to highly localised electric fields. It has recently been shown that focusing of electric fields at the cellular level, using an array of small electrodes, results in unexpectedly high cell transfection efficiencies. It has been termed 'close-field electroporation'. Here it is proposed t ....Tuning Molecular Translocaton by Close-Field Electroporation. This project aims to determine the underlying mechanisms by which DNA and other molecules are able to migrate across the cell membrane in response to highly localised electric fields. It has recently been shown that focusing of electric fields at the cellular level, using an array of small electrodes, results in unexpectedly high cell transfection efficiencies. It has been termed 'close-field electroporation'. Here it is proposed to establish the properties of the electric fields around cells and cell membrane interactions with these fields that enable molecular translocation. This fundamental science could have broad implications in the domains of drug delivery, gene therapy and neural stimulation.Read moreRead less
How filopodia connect macrophages to the outside world. Fundamental to life is the ability of cells to sense their surroundings and respond accordingly. This project aims to generate a biological understanding of how certain immune cells carry out such processes, thus enabling them to combat infections.
