Professor Colette McKay has conducted world-leading interdisciplinary research that vitally contributed to the efficacy of Australia’s most successful medical device, the cochlear implant. Her work, which combines behavioural studies with mathematical modelling, electrophysiology, and brain imaging, has derived important information about how the brain’s auditory pathways process electrical stimulation. She has applied this knowledge to the improvement of cochlear implants and to the development of an auditory midbrain implant for those who cannot benefit from a cochlear implant. Six patent families have flowed from Professor McKay’s work which is utilised by researchers and companies worldwide to benefit deaf individuals.
