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

This project will build hollow-core metamaterial waveguides, where the large dimension (a few millimetres) of current rigid waveguides will be reduced to a few tens of microns. This project will demonstrate tuneable spectral filtering using these novel waveguides, leading to realisation of the world's first hollow-core waveguide-based metamaterial device.

This project will develop novel, state-of-the-art circuits and design strategies that overcome the challenges of current and future Integrated Circuit (IC) fabrication technologies. The extremely small sizes of transistors in these technologies offer advantages in speed, but at the price of a number of drawbacks, which the project will aim to overcome in this work. This research will make a significant contribution to the field of IC design as well as providing training for students to fill the present and future needs of Australia's IC design companies. Some of the most advanced cochlear implants, mobile phone ICs, and Wireless Internet ICs have been designed in Australia, and companies in Australia desperately need graduates skilled in designing in the latest technologies.Read moreRead less

This project aims to develop optimal, efficient and robust signal processing methods for diffusion magnetic resonance imaging (dMRI) with reduced scan times. A child, possibly distressed, can only be motionless long enough to undergo a basic dMRI scan of the brain, but enhanced forms of dMRI need at least 60 minutes.

This project aims to develop optimal, efficient and robust signal processing methods for diffusion magnetic resonance imaging (dMRI) with reduced scan times. A child, possibly distressed, can only be motionless long enough to undergo a basic dMRI scan of the brain, but enhanced forms of dMRI need at least 60 minutes. The project’s processing methods will use spherical geometries, which encode information about white matter fibres in the brain, to collect and reconstruct images. The project is expected to reduce dMRI scan times and ultimately make non-invasive and inexpensive early detection of neurological disorders such as dementia feasible.Read moreRead less
Teaching old dogs new tricks: making ordinary glass both guide and modulate light in photonic chips. The continued revolution of telecoms, and other industries, by photonics demands active integrated photonics: chips that can switch, modulate and modify light. Currently this requires problematic materials. This project will innovatively combine breakthroughs in two areas: poling and laser writing, to produce active devices in standard silicate glass chips.
