Prof Colette McKay

Professor Colette McKay completed her undergraduate degree and PhD at the University of Melbourne in Physics and Mathematics and following this undertook clinical training in Audiology at the same institution. From 1989 to 2004 she held full time research fellow positions in the Department of Otolaryngology at the University of Melbourne. During this time, her research focussed on psychophysics, speech perception, and signal processing in cochlear implants, although she contributed more widely to other areas such as auditory processing in patients with schizophrenia.
In 1998 she was awarded a Senior/Principal Research Fellowship from the Garnett Passe and Rodney Williams Memorial Foundation and in 2003 an NH&MRC Principal Research Fellowship. In 2002 she was elected a Fellow of the Acoustical Society of America for her research to improve speech understanding in cochlear implant users.

In 2005 Colette took up a position as Chair in Auditory Sciences at Aston University in the UK, where she launched the auditory research program as well as developing and implementing an undergraduate degree in Audiology. From 2007 she was appointed Chair in Applied Hearing Research at the University of Manchester, UK, where she led the Audiology and Deafness Research Group, and was Director of Research for the School of Psychophysical Sciences. In 2009 she was awarded the Thomas Simm Littler prize for contributions to auditory research by the British Society of Audiology.

In 2013, Colette returned to Melbourne with the assistance of a Victorian State Government Senior veski Innovation Fellowship, to take up the role of Leader in Translational Hearing Research at the Bionics Institute. Colette currently holds honorary professorial fellowships at the University of Manchester and the University of Melbourne Departments of Otolaryngology and Medical Bionics.

Research fields of interest

  • Cochlear Implants – psychophysics, speech understanding, and signal processing
  • Modelling of temporal processing in the auditory system – application to signal processing
  • Deep Brain Stimulation – optimisation of stimulation parameters and fitting techniques

Research projects

  • Understanding the effect of brain plasticity on cochlear implant outcomes in adults using a novel brain imaging technique called functional near infra-red spectroscopy (fNIRS).

  • Understanding the effects of deafness and hearing device use on language development in infants and children using fNIRS.

  • Novel methods using EEG and fNIRS to fit hearing devices to infants, and verify their effectiveness.

  • Novel signal processing techniques to improve speech understanding with cochlear implants.

  • Improved outcomes for auditory brainstem implant (ABI) patients. This project aims to optimise outcomes of patients with an ABI by understanding how the auditory system processes stimuli applied to the brainstem. Patients are undergoing a series of psychophysical and speech perception studies. This project is in collaboration with MRC-CBU in Cambridge, UK.

  • Development of Auditory Midbrain Implants. This project aims to evaluate a new type of auditory implant that stimulates the Inferior Colliculus in the midbrain. It is a collaboration between team members in University Hospital Hannover (Germany), University of Minnesota (USA), Cochlear Ltd, and Professor McKay at the Bionics Institute.

  • Deep brain stimulation: Optimising patient outcomes.
