Meet our faculty researchers and see what they are up to

Our faculty and students are actively involved in several areas of research. View each researcher's page or lab website to learn more about their work and how you can get involved!

Researchers and their Labs

Dr. Ramesh Kaipa

Dr. Ramesh Kaipa

Dr. Kaipa is the head of the Motor Speech lab and his 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.

Dr. Valerie Freeman

Dr. Valerie Freeman

Dr. Freeman directs the Sociophonetics lab. She studies how acoustic-phonetic aspects of speech production and sociolinguistic perception vary with social factors like regional dialect and hearing status. Her largest projects investigate the lived experiences of d/Deaf and hard-of-hearing people and how their speech is perceived. Other projects examine remote data collection methods, regional vowel mergers, vocal gender perception, and ways to train abled native speakers to better understand accented and pathologized speech.

Dr. Roha Kaipa

Dr. Roha Kaipa

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

Dr. Peter Richtsmeier

Dr. Peter Richtsmeier

Dr. Richtsmeier is the head of the Phon Farm Lab and 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. Sabiha Parveen

Dr. Parveen is the head of the Adult Neuro and SOTL Research Lab and she investigates the effects of speech and cognitive treatment programs in adult neurogenic disorders including Parkinson disease, quality of life issues of people with neurogenic disorders and their families, and scholarship of teaching and learning (SOTL) in the field of Communication Sciences and Disorders.

John Tetnowski headshot

Dr. John Tetnowski

Dr. John Tetnowski is the Jeanette Sias Endowed Chair in Speech Pathology and director of the OSU Stuttering Research and Treatment Lab at Oklahoma State University. He has published over 90 manuscripts and has over 1000 citations in the professional literature. He is the only Board Certified Fluency Specialist in Oklahoma and is a Fellow of the American Speech-Language-Hearing Association. He directs the Cowboy Stuttering Camp, the Oklahoma State Chapter of the National Stuttering Association and is a co-founder of the Oklahoma Affiliates for the Knowledge of Stuttering.

Dr. Yu Zhang

Dr. Yu Zhang

Dr. Zhang's work revolves around speech perception and spoken word recognition in monolingual listeners and bilingual population in the face of common stimuli variability such as speaker variability and different levels of noise. His lab seeks to understand how people with different native listening backgrounds handle these common sources of variability in their processing of speech and recognition of spoken words at a more fundamental level, despite the seemingly negligible challenges.
