Research

Research interests 

My research focuses on hearing loss related to middle ear disease, and on ototoxicity, or damage to the ear by drugs, chemicals and noise. Our laboratory also develops animal and computer models of known ear diseases in order to increase our understanding of the pathophysiological processes involved and suggest new therapeutic modalities. This includes diseases caused by middle ear abnormalities and ototoxic medication.

Hearing loss is particularly important in children, as it affects the development of their language and social skills. At the McGill Auditory Sciences Laboratory, my research team develops models to further the diagnosis and treatment of drug-induced hearing loss. We are exploring ways to prevent platinum otoxicity, the form of hearing loss experienced by cancer patients. The loss is caused by toxic compounds released after exposure to the chemotherapeutic agent. 

This research will not only improve the quality of life for cancer survivors; it will also reduce restrictions on some of the most powerful agents used to fight cancer. Controlling the adverse side effect of ototoxicity may allow higher treatment doses of chemotherapy, and consequently better patient survival. 

Research foci 
  • Diagnosis and treatment of hearing disorders;
  • Middle-ear mechanics;
  • Ototoxicity;
  • Hearing development and diagnostics.
