Fulbright Distinguished Scholar, recipient - Christchurch, New Zealand

CAPCSD Distinguished Service Award, recipient

Fulbright Recipient, Trinity College, Dublin, Ireland

Fellow, American Speech-Language Hearing Association

Distinguished Service Award, CAPCSD

Fulbright Senior Specialist

• Deafness
• Cochlear implants and communication abilities
• Speech perception
• Aerodynamic studies of voice and speech production
• Acoustic analysis of speech

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
