    Dylan K. Chan, MD, PhD, is an Associate Professor in Residence and he is the Director of the Children’s Communication Center (CCC) in the Department of Otolaryngology – Head and Neck Surgery (ONHS) at the University of California, San Francisco. He received his PhD in Sensory Neuroscience from the Rockefeller University in New York, and he obtained his medical degree from Weill Medical College of Cornell University, New York. Dr. Chan completed his ONHS residency from Stanford University School of Medicine, California, followed by a Pediatric Otolaryngology fellowship at the Seattle Children’s Hospital, Washington.

    In 2014, Dr. Chan established the UCSF Children’s Communication Center, which is devoted to delivering multidisciplinary care for families of deaf and hard of hearing children, performing community outreach and education, and conducting clinical and translational research projects. By addressing existing shortfalls in care delivery and developing novel treatments, he hopes to significantly impact hearing health in children. His laboratory is interested in investigating the pathophysiology and genetics of hearing loss associated with mutations in Connexin 26, the most commonly affected gene in congenital hearing loss, and the development of gene therapy for hearing restoration.

    Dr. Chan is a scientific reviewer for various scientific journals, frequent invited speaker at local and national conferences, and has published over 15 articles
