The mechanochemical basis of cell polarity. This project aims to study how epithelial cells initiate polarisation, a major question in biology that conventional biochemical, cell biological and genetic approaches have not answered. This project will investigate the mechanochemical basis of symmetry breaking in the cellular cortex, a thin layer of actomyosin filaments underneath the plasma membrane, and how this forms signalling zones.

This project aims to study how epithelial cells initiate polarisation, a major question in biology that conventional biochemical, cell biological and genetic approaches have not answered. This project will investigate the mechanochemical basis of symmetry breaking in the cellular cortex, a thin layer of actomyosin filaments underneath the plasma membrane, and how this forms signalling zones. Understanding polarity is expected to improve epithelia manipulation in disciplines from tissue engineering to regenerative biology and reveal how epithelial architecture and physiology are generated.Read moreRead less
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 aims to develop novel technology for non-contact imaging of micro-mechanical properties in cells and tissues to answer fundamental questions of cell mechnanobiology. Based on principles of Brillouin light scattering, the project takes advantage of a radio-frequency lock-in detection scheme. The project will result in a real-time, high-sensitivity, non-contact 3D imaging solution for spatial characterisation of cell's local stiffness and compressibility. This will underpin the advancement of knowledge in the area of cell mechanobiology and the investigation of diseases, where microscale changes in cell mechanical properties lead to cell dysfunction and apoptosis.Read moreRead less
Artificial photosynthesis: developing a simple, functional light harvesting porphyrin-protein ensemble. Inspired by photosynthesis, in this project we will fabricate a light driven reaction centre using an array of artificial chlorophylls or porphyrins integrated into a synthetic protein. This centre has the potential to be used as a photocatalyst to, for example, split water into hydrogen and oxygen or be the active component of a solar cell.

Summary
Molecular-Scale Interaction of Nanomaterials with Biomembranes. This project aims to develop a holistic understanding of how nanoparticles, and nanomaterials in general, interact with cellular materials, via the cell membrane on a molecular level. To date, the precise mechanism by which nanomaterials, such as particles, colloids, and sheets, interact with cellular material is poorly understood.

To date, the precise mechanism by which nanomaterials, such as particles, colloids, and sheets, interact with cellular material is poorly understood.
This project expects to generate new, fundamental knowledge in the field, and establish a platform for high-resolution, in situ, molecular-scale imaging of nanoscale events at the biomembrane. This will develop a fundamental understanding of the dynamics of nanomaterial-cell interactions, and provide benefit in the development of next-generation nanomaterial-based therapeutics and diagnostic technologies.

The Protein Corona: Imaging the nanoparticle biological identity card. The project will determine how the intrinsic physico-chemical properties of nanoparticles translate into extrinsic biological properties through their interaction with physiological proteins in the body. This process is complex and poorly understood due to our inability to visualise it through standard imaging techniques.

The project will determine how the intrinsic physico-chemical properties of nanoparticles translate into extrinsic biological properties through their interaction with physiological proteins in the body. This process is complex and poorly understood due to our inability to visualise it through standard imaging techniques. The project aims to develop a new tool to visualise, study, quantify and design the protein ‘corona’. These are the adsorbed protein layers that are rapidly formed in contact with biological liquids which allow cells to recognise and process nanoparticles. The proteins are dependent on factors such as size, shape, surface chemistry and biological history of the particles. Being able to ‘read’ and ‘write’ the protein corona would enable efficient cellular targeting of pharmaceutical drugs.Read moreRead less
