Welcome to the Laryngeal Function Lab – the primary research and teaching lab of Dr. Christopher R. Watts. The purpose of the Laryngeal Function Lab is to create new knowledge and expand existing knowledge related to our understanding of laryngeal function in voice and swallowing with the goal of improving diagnostic and treatment approaches for individuals with laryngeal impairments.  Along with my team of collaborators and students, we investigate laryngeal function in normal and dysphonic (voice impairment) populations and also those with normal swallowing and dysphagia (swallowing impairment).  Recently we have developed an innovative line of research investigating how clinical subtypes of Parkinson’s disease differently impact laryngeal function in voice and swallowing.

The lab is housed within the Miller Speech and Hearing Clinic on the campus of Texas Christian University.

In my program of research I use acoustic, aerodynamic, and electrophysiological technologies to measure laryngeal function during voice production and swallowing. The laryngeal function lab utilizes state-of-the-art technology including:

  • Laryngeal Videostroboscopy
  • Acoustic & Aerodynamic Voice Analysis systems
  • Electromyography and Manometry
