Christian Sumner

Lecturer/Senior Lecturer

School of Social Sciences

Role

Chris Sumner is an auditory neuroscientist and a Senior Lecturer in the Division of Psychology. He has a background in engineering and has studied various aspects of how we hear.

Career overview

Chris has a PhD in Computer Science from Imperial College London, where he first became interested in how the brain processes sound. He conducted his postdoctoral research in The University of Essex and the University of Michigan. In 2004 he joined the MRC Institute of Hearing Research where he led a program of research into the neural correlates of auditory perception and the underlying computations. He joined NTU in 2019.

Research areas

Chris’ research focuses on understanding the neural computation underlying how we hear. He does this with a variety of methods, but often by building computer models (simulations) of neurons, neural systems, and machine learning models, with the aim of relating processing by single neurons to our perception of sound. He believes that this understanding is critical in order to tackle the problems associated with hearing loss.

Recent research interests include:

  • How the neural coding of sound is altered by hearing loss and how this might affect speech recognition in complex environments (e.g. cocktail parties).
  • How low-level sensory processing influences the coding and recognition of complex acoustic signals such as (but not limited to) speech.
  • The mechanisms underlying resolution of sound frequency in the auditory system, from the cochlea to the cortex, and perception.
  • Neural adaptation in the auditory system: mechanisms and perceptual consequences.
  • Audiovisual integration of speech.
  • Neural processing of acoustic cues for sound localisation.
  • Modelling the response of auditory nerve to cochlear implant electrical stimulation.
