The faculty members in the Department of Communication Sciences and Disorders are active in researching different areas of the field.

Dr. Cheryl Giddens

Dr. Giddens is interested in exploring the effects of neuropathologies and their behavioral therapies on voice and velopharyngeal function. Some of her other projects look into the effects of stress, gastric reflux, and the menstrual cycle on normal voice production.

Dr. Ramesh Kaipa

Dr. Kaipa’s research focuses on the motor aspects of speech production. He investigates the outcomes of different treatments designed to improve speech production. His outcome measures include electrophysiological (electromyography and electroencephalography) and behavioral (acoustic) measures.
Motor Speech Lab

Dr. Peter Richtsmeier

Dr. Richtsmeier conducts research on phonological learning in children and adults. With children, his current studies examine 1) factors that contribute to the development and persistence of phonological errors, especially in children with speech sound disorder, and 2) factors that allow children to be more accurate speakers. With adults, current studies examine 1) factors that allow adults to learn phonological patterns, and 2) the basic cognitive skills required for phonological learning.

Dr. Sabiha Parveen

Dr. Parveen’s investigates the relationships between speech performance, motor performance, executive functioning, and quality of life with different motor speech disorders.

Dr. Valerie Freeman

Dr. Freeman studies how acoustic-phonetic aspects of speech production and sociolinguistic perception vary with social factors like regional dialect, stance-taking, and hearing status. Her current work investigates the speech intelligibility of deaf people who use cochlear implants (CIs) and how people with hearing loss are perceived socially when others hear their speech.
Sociophonetics Lab

Dr. Yu Zhang

Dr. Zhang's work concerns speech perception.  [details coming soon]

Dr. Roha Kaipa

Dr. Kaipa examines the effect of bilingualism/multilingualism on language learning, language processing and language production. Her outcome measures include electrophysiological (electromyography & electroencephalography) and behavioral measures.
