Taha Jan, M.D.

Resident Taha Jan in lab coat

Originally from Slemani, Kurdistan, Dr. Taha Jan graduated summa cum laude with a bachelor's in molecular and cellular biology with honors from Vanderbilt University. As an undergraduate, he worked in the laboratory of Dr. Larry Zwiebel on the olfactory system and in the laboratory of Dr. Robert Waters investigating the somatosensory cortex and gustatory system. He then attended medical school at Stanford University School of Medicine, where he studied the role of the Wnt pathway in murine cochlear development under the tutelage of Dr. Alan Cheng. He spent an extra year as a Howard Hughes Medical Institutes research fellow while at Stanford to further pursue his research interests on cochlear development, stem cell biology, and regenerative medicine.

Dr. Jan completed his internship in general surgery at Mass General Hospital and is currently a Chief Resident in the Mass. Eye and Ear/Harvard Medical School Otolaryngology Residency Program. His work during residency has focused on the effects of secreted factors from human vestibular schwannomas on hearing loss in the Eaton-Peabody Laboratories as part of Dr. Tina Stankovic’s group. Dr. Jan’s research interests continue to include development of the inner ear and stem cell biology with the goal of ultimately translating discoveries in these areas into therapeutics for patients suffering from hearing and vestibular disorders.

Upon completion of his residency, Dr. Jan will be starting a fellowship at Stanford University in the Clinician Scientist Training Program in Otolaryngology.
