Aaron M. Johnson, MM, PhD, CCC-SLP, is a researcher and speech–language pathologist specializing in voice habilitation and rehabilitation and is currently an Associate Professor in the Department of Otolaryngology at New York University School of Medicine. His research laboratory, funded by the National Institutes of Health, uses novel translational research methods to examine the effects of vocal training on laryngeal neuromuscular mechanisms in the aging larynx. As a clinician at the NYU Voice Center, he works with his physician colleagues to diagnose and treat voice disorders in performing artists. Both his research and clinical interests stem from his previous decade-long career as a professional classical singer and teacher of singing. Dr. Johnson holds degrees in vocal performance from Northwestern University, a certificate in vocology from the National Center for Voice and Speech, and a research doctorate from the University of Wisconsin-Madison. He is actively involved in the American Speech-Language-Hearing Association and the National Association of Teachers of Singing, and is President of the Pan American Vocology Association.
