Dr. Kokkinakis earned a Ph.D. in Electrical Engineering from the University of Liverpool. As director of the Electrical Hearing Laboratory at KU, Kokkinakis and his students are working on signal processing strategies for use in cochlear implant devices.

Education

Ph.D., Electrical Engineering, University of Liverpool

M.S., Electrical Engineering, University of Liverpool

B.S., Electrical Engineering, University of Sheffield

Teaching Interests

  • Physics of speech
  • Principles of hearing science
  • Psychoacoustics

Research

Dr. Kokkinakis' research focuses on signal processing, binaural hearing mechanisms and psychoacoustics. His research aims to enhance speech perception in noise by cochlear implant listeners.

Research Interests

  • Noise reduction for bilateral cochlear implants
