John S. Oghalai, MD

Dr. Oghalai is a Professor and Department Chair of Otolaryngology–Head and Neck Surgery at USC. He has followed a clinician-scientist pathway, both caring for patients and performing research in the lab. His clinical areas of focus are acoustic neuroma (vestibular schwannoma) surgery, chronic ear disease, and cochlear implantation. His NIH-funded lab seeks to better understand the fundamental changes within the inner ear that underlie progressive hearing loss and to develop novel techniques to treat this problem before it worsens.

Prior to joining USC, he was an Instructor at UCSF from 2001-2003 where he did fellowship training in Neurotology and Skull Base Surgery. He joined the faculty at Baylor College of Medicine in 2003 as an Assistant Professor and was promoted to Associate Professor in 2009. In 2010, he moved to Stanford University as an Associate Professor, and was promoted to Professor in 2015. In 2017, he took his current position at USC.
