This project aims to discover how a biologically inspired auditory model can be tightly integrated into a state-of-the-art deep learning speech processing framework, to model, design and verify a deep learning based auditory model. Voice-based technologies, ranging from cochlear implants to smart homes, are growing at a rapid pace and speech interfaces are being integrated with all aspects of our lives. However, there is a growing demand to improve these voice-enabled services, making them more secure and less open to cyber-crime attack by unauthorised users. The project is expected to improve techniques for modelling and automatic processing of speech and audio signals, which should provide significant benefits, including improved voice biometrics and cochlear implants.Read moreRead less

High efficiency thin-film gallium arsenide solar cells. Recent developments in GaAs-based solar cells have led to efficiencies above 30%. Widespread adoption of GaAs-based solar cells for space applications has also brought about large reductions in material costs. However, GaAs cells are still much more expensive than silicon cells.

Widespread adoption of GaAs-based solar cells for space applications has also brought about large reductions in material costs. However, GaAs cells are still much more expensive than silicon cells. This application addresses the development of a manufacturable technique for lifting off thin films of GaAs. This approach allows a significantly reduced cost due to reduced materials usage, while maintaining high efficiency. Light-trapping for lifted-off cells will also be developed, which will allow the theoretical limit to performance to be approached, and fundamental processes in GaAs to be investigated.

This project aims to determine the role of common glass constituents on desired optical properties. More than 50 major research groups and numerous commercial start-ups worldwide are pursuing ultrafast laser inscription, an enabling manufacturing platform used to create complex three-dimensional optical circuits inside transparent blocks of glass. However, although successfully used, we still don’t understand why similar glass types react differently, and we are limited to using generic glasses tailor-made for other purposes. This project will guide future choice of glasses and reveal how to engineer materials that complement this fabrication platform.Read moreRead less
