Patient Care

Dr. Michael has been a singer all her life and a singing teacher for 30 years, and therefore has an expertise in treating voice problems in professional voice users such as singers, actors, and teachers.  A common part of her practice is to return injured singers to the stage.  She also has an expertise in functional breathing problems, particularly in athletes, and she draws on her experience as a runner in treating these disorders.

Research

Dr. Michael currently has a number of research projects regarding the objective measurement of speaking and singing voice quality, most especially acoustic and perceptual evaluation of singing.  Results of her studies are presented regularly at national and international conferences, most especially the Voice Foundation’s Annual Symposia on the Care of the Professional Voice, and the International Conferences on the Physiology and Acoustics of Singing.  Other research activities include research on various treatments for voice disorders, most especially for unilateral vocal fold paralysis.
