Research Description
We study the mammalian inner ear by answering fundamental questions of development and regeneration and performing translational research using disease models of hearing loss. Our research aims to transform the understanding of hearing loss and identify the mechanisms that can be targeted for diagnosis and treatment of patients suffering from hearing and balance impairment.
Clinical Description
Dr. Taha Jan is an Assistant Professor of Otolaryngology - Head and Neck Surgery and is a fellowship-trained and board-certified Otologist, Neurotologist, and Skull Base Surgeon. He graduated summa cum laude with a bachelor's in Molecular and Cellular Biology with Honors from Vanderbilt University prior to attending medical school at Stanford University. During medical school, he completed a one year Howard Hughes Medical Institute (HHMI) research fellowship in cochlear development, stem cell biology, and regenerative medicine. Dr. Jan then went onto his internship in General Surgery at the Massachusetts General Hospital (MGH) followed by residency in Otolaryngology - Head and Neck Surgery at the Massachusetts Eye and Ear Infirmary / Harvard Medical School Program in Boston. He then completed the Stanford University Clinician Scientist Training Program, a T32 postdoctoral research fellowship followed by Otology, Neurotology, and Skull Base Surgery clinical fellowship. He was an Assistant Professor at UCSF for 2 years prior to joining VUMC in July 2022.

Dr. Jan is a surgeon-scientist with a research interest in developmental and regenerative biology of the inner ear with the ultimate goal of translating discoveries in the laboratory to therapies in the clinic and operating room.

Otology, Neurotology, and Skull Base Surgery

Treatment of diseases and tumors of the temporal bone and lateral skull base, including the external ear canal, middle ear, and inner ear. These include hearing loss, otosclerosis, stapes surgery, cholesteatoma, cochlear implantation, tympanic membrane perforation, sudden sensorineural hearing loss, acoustic neuroma (vestibular schwannoma), meningioma, paraganglioma, and other skull base tumors.
