Summary of current research

Research Interests

  • Immune-mediated inner-ear disease and hearing loss
  • Intratympanic delivery of steroids for improved recovery of hearing loss
  • Development of novel treatments for hearing loss
  • Ion and water transport dysfunction in different forms of hearing loss
  • Control of inflammatory processes of the middle ear
  • Impact on middle-ear inflammation on the inner ear

Major Milestones and Significant Discoveries

  • New treatment for sudden and immune-mediated hearing loss
  • Demonstration that inflammatory processes occur in the inner ear with middle-ear infections
  • Identification of fluid-clearing mechanisms in the middle-ear compromised during infections, leading to the painful effusions found in otitis media
  • Identification of potential gene defects that cause middle-ear infections
