Seminar - Biomechanical Measurement and Modeling of Sound Transmission in Normal, Diseased, Implanted Ears by Dr. Rong Zhu GAN

Date:   23 July 2013 (Tuesday)

Time:   2:30 pm – 3:30 pm

Venue:  EF305, The Hong Kong Polytechnic University

Abstract:

Hearing impairment is one of the most common physical disabilities in the world. Conductive hearing loss results from dysfunction of the middle ear, and sensorineural hearing loss results from abnormalities within the cochlea or central nervous system. We have used bioengineering ethodology, a combined physiological, anatomical and engineering approach through both experimental easurement and computational modeling, to describe ear biomechanics for sound transmission through the external ear canal, middle ear and inner ear, and to develop middle ear implantable hearing devices, a new emerging technology for sound amplification. This talk will report our research accomplishments in those areas.

Biosketch:

Dr. Gan received her Ph.D. in Biomedical Engineering from the University of Memphis, and is the Charles E. Foster Chair and Professor in Biomedical and Mechanical Engineering in the School of Aerospace and Mechanical Engineering at the University of Oklahoma (1999-present). Her previous appointments include the Director of Engineering at Hough Ear Institute in Oklahoma City (1995-1999); Research Associated Scientist at the Lovelace Research Institute in Albuquerque, New Mexico (1994-1995); and Postdoctoral Research Associate at the University of Memphis (1992-1994). Dr. Gan’s NIH funded research programs focus on middle ear and cochlea mechanics and implantable hearing devices. Her current research activities cover the following areas: measurement of sound transmission in normal, diseased and reconstructed ears with laser Doppler vibrometry and physiology/audiology measuring tools, characterization of mechanical properties of the ear tissues; 3D reconstruction and computational modeling of the human and animal ears; and implantable hearing devices – design, testing, and modeling. Dr. Gan holds two patents: “Totally Implantable Hearing System” and “3-Dimensional Finite Element Computational Model of Human Ear”, and has published over 250 research articles in peer-reviewed journals, conference proceedings, and book chapters in the fields of hearing research, tissue and organ biomechanics, and theoretical modeling of physiological systems.
