Central Representation of Electroacoustic Stimuli. Cochlear implantation, initially only provided to profoundly deaf individuals, is now routine in people with substantial residual hearing. Although stimulation via a cochlear implant and hearing aid in the same ear has been shown to improve speech understanding, particularly in noise, and to increase the aesthetic quality of sound, almost nothing is known about the physiological mechanisms underlying these benefits. The broad aim of our project ....Central Representation of Electroacoustic Stimuli. Cochlear implantation, initially only provided to profoundly deaf individuals, is now routine in people with substantial residual hearing. Although stimulation via a cochlear implant and hearing aid in the same ear has been shown to improve speech understanding, particularly in noise, and to increase the aesthetic quality of sound, almost nothing is known about the physiological mechanisms underlying these benefits. The broad aim of our project is to address this deficiency by measuring the patterns of neural activity evoked by speech sounds across the tonotopic axis in the inferior colliculus and auditory cortex and assess the extent to which the pattern of neural activity allows discrimination between the different speech sounds.Read moreRead less
Ultra-low fouling active surfaces. This project aims to develop chemistries and fabrication approaches through innovative materials evaluation to develop ultra-low fouling active electrode surfaces. Development of ultra-low fouling surfaces will have significant impact in a range of applications where system or device failure is attributed to fouling. The growing field of bionics, where implantable electronic devices interface directly with the nervous system, is one such device. The expected ou ....Ultra-low fouling active surfaces. This project aims to develop chemistries and fabrication approaches through innovative materials evaluation to develop ultra-low fouling active electrode surfaces. Development of ultra-low fouling surfaces will have significant impact in a range of applications where system or device failure is attributed to fouling. The growing field of bionics, where implantable electronic devices interface directly with the nervous system, is one such device. The expected outcomes will be an understanding of the material requirements that lead to the elimination of protein and cell accumulation at surfaces that degrades the performance and lifetime of these implants. The findings will benefit any application where fouling is a problem.Read moreRead less
Supercritical-microfluidics technology for targeted delivery to the colon. This research will develop nanosystems to target delivery of drugs to the colon. Our nanosystems will permit the combination of clinically used chemotherapy drugs within a single dosage form. This will improve the efficiency of delivery to the colon while reducing unwanted side-effects. A novel supercritical microfluidics system will be developed to produce therapeutic nano-carriers in a continuous mode with lower labour ....Supercritical-microfluidics technology for targeted delivery to the colon. This research will develop nanosystems to target delivery of drugs to the colon. Our nanosystems will permit the combination of clinically used chemotherapy drugs within a single dosage form. This will improve the efficiency of delivery to the colon while reducing unwanted side-effects. A novel supercritical microfluidics system will be developed to produce therapeutic nano-carriers in a continuous mode with lower labour requirement, higher production rate and better quality control than conventional production methods. The new process will combine benefits from both supercritical fluid technology (green process) and microfluidics (high mass & heat transfer).Read moreRead less
