Dallas Cochlear Implant Program Laboratory

The Dallas Cochlear Implant Program (DCIP) Laboratory housed at the Callier Advanced Hearing Research Center is one of several research arms associated with the DCIP, a joint endeavor of The University of Texas at Dallas, The University of Texas Southwestern Medical Center and Children’s Medical Center to provide quality care for individuals using cochlear implants.

Research activities in the UT Dallas Callier-based laboratory focus on early communication development in children using cochlear implants, cortical plasticity and neural responsiveness to electrical hearing, literacy development and speech intelligibility. In addition, the laboratory is engaged in clinical trials associated with new products designed to assist individuals with hearing impairments.
