Dr. Gan’s research activities are developed in 5 areas covering both basic and applied researches. These 5 areas are:

  1. Measurement of sound transmission in human cadaver and animal ears using laser Doppler interferometry;
  2. Biomechanics of tissues, organs and systems such as the ear tissues and auditory system;
  3. 3-dimensional reconstruction and computational modeling of human and animal ears;
  4. Measurement and simulation of blast or high intensity sound transmission through the ear;
  5. Implantable hearing devices – design, testing and modeling of totally implantable hearing system.
The research goals are: to determine how the structure and mechanical properties of the ear affect the sound transmission through the external ear canal and middle ear to inner ear or cochlea, and to improve diagnostic effectiveness for middle ear diseases and rehabilitation techniques for restoration of hearing. Dr. Gan use biomechanics systems methodology, a combined physiological, anatomical and engineering approach through both experimental measurement and computational modeling to reach these goals.
