Dr. Jin Xu has been working in cochlear implant research as a Research Fellow in the Department of Otolaryngology, The University of Melbourne, The Bionic Ear Institute, CRC for Cochlear Implant and Hearing Aid Innovation and HEARing CRC since 1987.

She received her Bachelor Degree of Medicine and Surgery, Mater Degree of Medicine, Diploma of Radiology in Shanghai, China. She was a radiologist in Eye and ENT Hospital affiliated with Shanghai Medical University (now Fu dan University) before she came to Australia in 1985. In 1995, she received Statement of Accreditation in Diagnostic Radiography from Professional Accreditation and Education Board, Australian Institute of Radiography. She received Certificate of registration to practise as a Medical Imaging Technologist in Australia.

Research Fields of Interest

  • Chronic electrical stimulation of the auditory nerve - physiological and histological study.
  • Development of the “Cochlear View”, a post-operative radiological method for demonstration of the position of intra-cochlear electrodes and evaluation of the depth of the insertion for cochlear implantees.
  • Development of pre-curved scala tympani electrode array
  • Designing custom-made scala tympani electrode assemblies for acute and chronic electrical stimulation of the auditory nerve in animal models
  • Development of surgical methods for cochlear implantation in small animal models.
  • Utilizing the latest technology in x-ray imaging to establish a Micro-focus X-ray Imaging Lab, working closely with Cochlear Ltd. to assist the development of intra-cochlear electrode arrays with optimal designs by providing real-time fluoroscopic image and high resolution still image.
  • Micro-focus x-ray for cochlear implantation on small animals.
