Dr. James Mahshie is a Professor in the Department of Speech and Hearing Sciences at the George Washington University. His expertise lies in the areas of deafness, aerodynamic studies of voice and speech production, and acoustic analysis of speech. Dr. Mahshie has had a number of funded projects aimed at examining the speech production and perception skills of children who are deaf or hard of hearing. His current work is focusing on addressing hearing healthcare inequities in children with hearing loss. Among the aims of his previous research are:

Improved understanding of the physiological underpinnings of speech production by those with hearing loss,
Development and assessment of various computer-mediated approaches to improving speech production by deaf individuals,
Study of the relation between perceptual capacity for certain speech features and the ability to use these features in speech production, and
Exploration of factors contributing to speech sound production deficits in children with cochlear implants.
