Ryan C. Branski, PhD

Ryan C. Branski, PhD

Ryan Branski is the Howard A. Rusk Professor of Rehabilitation Research, Vice Chair for Research in Rehabilitation Medicine, and Professor of Otolaryngology-Head and Neck Surgery at the NYU Grossman School of Medicine. His laboratory seeks to develop and refine therapeutic approaches for diseases of the upper aerodigestive tract that manifest as speech, voice, and swallowing disorders. His collaborative team takes a regenerative medicine approach to these issues with a particular interest in localized delivery of gene therapy to the larynx as well as tissue engineering constructs to address deficits in communication and deglutition. Dr. Branski's laboratory is funded by the National Institutes of Health and he has published over 130 peer-reviewed manuscripts. He is a frequent speaker at national and international scientific meetings and is one of only a few investigators to be named Fellow of the American Speech Language Hearing Association, the American Laryngological Association, and the Academy of Otolaryngology-Head and Neck Surgery. 

Aaron M. Johnson, MM, PhD, CCC-SLP

Aaron M. Johnson, MM, PhD, CCC-SLP

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 the former president of the Pan American Vocology Association.
