Our Staff

The NCRAR is cultivating a community of clinicians, research scientists, and scholars who can address the communicative, economic, psychosocial, and vocational issues associated with auditory disorders. The Center is unique because of the broad range of professionals who work together with a focus on delivering rehabilitative therapeutics within the lifetime of the Veteran, with the greatest effectiveness and in a way that promotes efficiency.

Currently, more than 40 professionals are engaged in a variety of research and development activities of the NCRAR. Working alongside auditory research scientists and audiologists, it is commonplace to find such other professionals as healthcare educators, immunologists, otolaryngologists, neurologists, neuropsychologists, oncologists, and speech-language pathologists.
