The Voice Lab, located in the Department of Communication Sciences and Disorders, is equipped to study aerodynamic, acoustic properties of voice production, and visual inspection of the larynx via rigid laryngoscopy and videostroboscopy.

Dr. Grillo's research interests and clinical specialization involve voice production. Currently, her research agenda related to voice includes three major areas: 1) aerodynamic, acoustic, and perceptual measures of voice in different populations including patients with voice disorders and heavy occupational voice users; 2) application of her Global Voice Prevention and Therapy Model; 3) app technology applied to voice; and 4) telepractice methods for the prevention of voice disorders in student teachers.

She is currently investigating the ability of aerodynamic measures to distinguish different phonation patterns in healthy voice users and in patients with voice disorders. Specifically, a phrase is being compared to repeated /pi/s for capture of airflow and subglottic pressure in healthy voice users and in patients with voice disorders at pre- and post-therapy.   

Secondly, she plans to apply her Global Voice Prevention Model to vocally healthy student teachers at WCU through two methods, 1) traditional in-person and 2) online, telepractice.  A smartphone app will be used to record primary and secondary outcome measures.

Dr. Grillo would welcome the opportunity for collaboration with individuals who share the same interests. Student interest is highly valued to promote the research process in future generations of speech-language pathologists.
