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

Dr. Grillo's research interests and clinical specialization involve voice production. Currently, her research agenda 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) development and application of her Global Voice Therapy Model; and 3) the influence of auditory and kinesthetic feedback in the production of different voice patterns.

She is currently investigating the ability of aerodynamic and acoustic measures to distinguish different phonation patterns in the adult non-voice disordered population. Future investigation of specific aerodynamic and acoustic measures will involve their ability to distinguish voice changes from pre-voice therapy to post-voice therapy in patients with voice disorders. In addition, she is investigating the voice characteristics of student teachers with the ultimate goal of developing a voice disorders prevention paradigm. The voice characteristics are being captured by acoustic, aerodynamic, and perceptual measures.

Secondly, she is also developing her Global Voice Therapy Model (GVMT)which contains four major components dedicated to improving generalization and maintenance of newly learned voice patterns. The GVTM will be investigated for its preliminary effectiveness during the fall 2008 semester by Dr. Grillo at an area healthcare facility. Pre- and post-treatment clinical data will be recorded. This project will serve as Phase I and Phase II of the five-phase model of clinical-outcome research suggested by Robey (2004). This project is being supported by a Faculty Professional Development Council Grant at West Chester University.

Finally, Dr. Grillo is interested in studying the influence of auditory and kinesthetic feedback on the production of extreme voice patterns. Her dissertation work focused on the population of vocally trained female singers. She is interested in expanding the population to untrained subjects and even patients with voice disorders.

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.
