Laboratory for Brainstem

and Inner Ear Neurobiology

We study how Sensory cells and neurons are specified and differentiate to better understand Nervous system development and pathogenesis of disease.

The Duncan lab utilizes transgenic mice to model biological processes related to human development and disease. Our work focuses on understanding:

  • The gene regulatory networks necessary for inner ear development and hearing restoration in patients with Age Related Hearing Loss

  • Prevention of hearing loss

  • Development of cranial motor neurons and disorders in axonal guidance.

  • Specification and connectivity of hindbrain neurons involved in sudden infant death syndrome (SIDS).
