Laryngeal Physiology Laboratory

Laryngeal Physiology Laboratory

The Laryngeal Physiology Laboratory has been active in research for over 20 years and is designed to conduct in vivo experiments in laryngeal physiology. The laboratory is a fully equipped surgical suite designed to study how the larynx controls voice production.  The goal is to expand our understanding of voice disorders in a laboratory setting and to translate the findings into clinical care of people with voice disorders.

Current Research Projects

  • Neuromuscular control of the larynx
  • Ex vivo living larynx
  • Laryngeal transplantation
