Controlling Defects in 2D Materials for Advanced Optoelectronics. Control over defect densities in 2D transition metal chalcogenide films permit controlled fabrication of van der Waals heterostructures and other ultra-thin electronic devices. This is crucial for controlling the optoelectronic properties of devices, yet, unlike bulk semiconductors, defect and dopant control in 2D transition metal chalcogenides is not presently possible.

Control over defect densities in 2D transition metal chalcogenide films permit controlled fabrication of van der Waals heterostructures and other ultra-thin electronic devices. This is crucial for controlling the optoelectronic properties of devices, yet, unlike bulk semiconductors, defect and dopant control in 2D transition metal chalcogenides is not presently possible. This project aims to investigate the optical properties of single-defects, and how to control them using sensitive microscopy and controlled ligand deposition. Simultaneous electronic characterisation and single-defect microscopy in fabricated thin-film transistors will be investigated to correlate optical and electronic properties of thin-film devices.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

The nanotechnology sector is experiencing an exponential growth period with over 100 products containing manufactured nanoparticles entering the market every year. Ensuring growth of the sector needs to be balanced against the imperative of protecting both human and environmental safety. This project aims to develop new methodological and conceptual avenues to close the gap between innovation in nanotechnology and risk assessment. This is intended to be achieved by developing and validating high-throughput in vitro toxicity screening platforms for manufactured nanoparticles. The approach is based on advanced lab-on-a-chip microfluidic technologies. The predictive power of the platform will be refined and optimised via ex-vivo and in-vivo models.Read moreRead less
