Summary
Conferring life-like functions to protocells. For life to have arisen, simple self-assembled chemicals must have performed key life-like functions. This project aims to generate new knowledge in the fields of soft condensed matter physics and astrobiology by understanding how primitive life could have obtained nutrients and completed “cell” division without proteins. This ambitious goal is expected to not only contribute towards understanding the origins of life, one of the grand challenges in s ....Conferring life-like functions to protocells. For life to have arisen, simple self-assembled chemicals must have performed key life-like functions. This project aims to generate new knowledge in the fields of soft condensed matter physics and astrobiology by understanding how primitive life could have obtained nutrients and completed “cell” division without proteins. This ambitious goal is expected to not only contribute towards understanding the origins of life, one of the grand challenges in science, but also to elucidate principles in membrane biophysics and self-assembly. The fundamental scientific findings will be applied to making responsive capsules that can confer advanced functionalities to soft materials. Several international collaborations are anticipated.Read moreRead less

This project aims to develop a foundation for understanding how microscopic topology and intermolecular interactions control the flow behaviour of supramolecular polymer networks. Brownian dynamics algorithms will be developed to unravel the complex dynamics of the network and calibrated by comparison with carefully designed experiments. The expected outcome of the project is a quantitative framework for connecting the molecular structure and energy landscape with resulting macroscopic properties. This project should yield significant benefit in the rational design of supramolecular systems in which the thermorheological properties can be tuned over a wide range of force/time scales with applications spanning from enhanced oil recovery to injectable hydrogels.Read moreRead less
The geometry of genome access: lessons from HIV. Access to the cell’s nucleus, and hence its genome, is of deep scientific and commercial significance. It is controlled by a phase-separated diffusion barrier within the nuclear pore complex. Recent evidence, however, has shown that HIV can cross this barrier with its protective capsid intact, despite it being over one thousand times larger than the limit for passive transport. Combining concepts from soft-matter physics with recombinant assays, t ....The geometry of genome access: lessons from HIV. Access to the cell’s nucleus, and hence its genome, is of deep scientific and commercial significance. It is controlled by a phase-separated diffusion barrier within the nuclear pore complex. Recent evidence, however, has shown that HIV can cross this barrier with its protective capsid intact, despite it being over one thousand times larger than the limit for passive transport. Combining concepts from soft-matter physics with recombinant assays, this project aims to uncover the link between the unique geometry of HIV capsids and their ability to subvert the nucleus’ defenses. The expected outcome is a step-change in the understanding of nuclear access control, with downstream benefits to virology, bio-engineering and bio-technology.Read moreRead less
Rational design of new synthetic antifreeze molecules for cryopreservation. This project aims to synthesise new carbohydrate-based surfactants optimised for use as cryoprotectants, and to accurately measure, model and optimise their performance. The project will use state-of-the-art experimental methods and advanced phase-field modelling techniques to optimise the cryoprotectants so that they reduce osmotic stress in cells and inhibit ice crystal growth during freezing and thawing.

This project aims to synthesise new carbohydrate-based surfactants optimised for use as cryoprotectants, and to accurately measure, model and optimise their performance. The project will use state-of-the-art experimental methods and advanced phase-field modelling techniques to optimise the cryoprotectants so that they reduce osmotic stress in cells and inhibit ice crystal growth during freezing and thawing. The expected outcomes will be novel cryoprotectants that are easy to synthesise, non-toxic and effective, opening up new possibilities for the cryopreservation of cells, organs and possibly even whole organisms. This will have broad impact in critical applications such as long-term blood storage, reproductive technology and stem cell therapy, as well as preservation of endangered species.Read moreRead less
Meta-microscopy of insect tissue: How nature grows bicontinuous nanosolids. Several butterfly species grow a complex nano-sculptured matrix whose chiral network structure confers remarkable optical properties, including jewel-like reflections. The formation process remains mysterious and a spectacular case of bottom-up self-assembly at far larger scales than accessible in the lab. The project aims to decipher this process, by (a) tomography of a species where arrested growth sites represent time ....Meta-microscopy of insect tissue: How nature grows bicontinuous nanosolids. Several butterfly species grow a complex nano-sculptured matrix whose chiral network structure confers remarkable optical properties, including jewel-like reflections. The formation process remains mysterious and a spectacular case of bottom-up self-assembly at far larger scales than accessible in the lab. The project aims to decipher this process, by (a) tomography of a species where arrested growth sites represent time-frozen snapshots of the development, and (b) by a combination of micron-resolved in-vivo microscopy of a developing butterfly wing with a growth model to infer nanometer-scale information. This insight will lead to blueprints for self-assembly strategies and shed light on function and form of inner-cellular membranes. Read moreRead less
