James Mahshie is a professor in the Department of Speech, Language and Hearing Science. He has served on a number of committees within GW and has served the profession in various leadership roles including president of the American Association of Phonetic Sciences and president of the Council of Academic Programs in Communication Sciences and Disorders, coordinator of the Special Interest Group on Pediatric Hearing and Hearing Loss for the American Speech, Language and Hearing Association (ASHA). He was elected a fellow of ASHA in 2003. Mahshie’s research program examines speech production and perception by children with cochlear implants and he recently initiated a collaboration with researchers from China on a range of projects focusing on deaf children. Dr. Mahshie teaches undergraduate and graduate courses in SLHS and mentors both undergraduate and graduate research.

Dr. Mahshie’s research involves exploration of various aspects of speech production and perception by deaf and hard of hearing individuals. His research includes studies aimed at:
- Characterizing prosody production and perception in children with cochlear implants
- Examination of factors predictive of speech sound production accuracy
- Exploration of sensory factors contributing to literacy development in children with hearing loss
- Study of the relation between perceptual capacity for certain speech features, and the ability to use these features in speech production
- Recently he has been involved in collaborative work aimed at addressing disparities in hearing healthcare among underserved populations
