As a member of the Tillotson Cell Biology Unit, Dr. Dunia Abdul-Aziz studies basic biology of sensory hair cell development and regeneration. These hair cells reside in the hearing organ (the cochlea) and are crucial for converting wavelength of sound into electrical signal. Their loss is the most common cause of sensorineural hearing loss. Dr. Abdul-Aziz seeks to understand the basic mechanisms underlying their development and regeneration with the purpose of translating this knowledge to restore hearing.
