Research Interest Summary

Central Auditory Plasticity/Neuron-glia Interaction

Research Interests

Conductive hearing loss impacts social integration- people who are affected by it often become socially isolated. In contrast to complete deafness, the effects of partial hearing loss on the auditory brain are poorly understood. Since hearing impairment is much more prevalent in humans than complete deafness, there is an urgent need to investigate the cellular changes that occur in the central auditory pathway of the hearing impaired. Research in Dr. Rubio's laboratory focuses on elucidating the molecular, anatomical electrophysiological and behavioral changes in central auditory structures in response to conductive hearing loss.
