Spoken Language Processing Lab

Brittan A. Barker, Ph.D., Director

About Dr. Brittan A. Barker

Dr. Barker is a developmental cognitive hearing scientist with an emphasis on talker-specific spoken language processing in listeners with and without hearing loss. Prior to her faculty position at Louisiana State University (LSU), Dr. Barker spent nearly 10 years as a clinical researcher at University of Iowa’s Hospitals and Clinics on the Children’s Cochlear Implant (CI) Program where she independently established one of the world’s first Infant CI Speech Perception Labs. Dr. Barker’s research has continued along similar lines in her faculty position at LSU where she explores the development of spoken language processing across listeners with a variety of hearing levels—from listeners with normal hearing to listeners with Auditory Processing Disorders to listeners with bilateral CIs.

While at LSU, Dr. Barker has served as a grant reviewer for multiple national and international directorates including The Netherlands Organisation for Scientific Research (the Dutch Research Council). Dr. Barker has secured over a quarter million in grant dollars as Principle Investigator from state and federal agencies including the National Institutes of Health and has published her research in journals across multiple disciplines including psychology, audiology, speech language pathology, and otolaryngology.
