Communication Sciences & Disorders

The research interests in the Department of Communication Sciences and Disorders (COMD) are quite varied and include all facets of the communication sciences. Our research contributes to the body of knowledge related to communication sciences and disorders, helps educate the future clinical-scientists and researchers, and is used to inform the latest intervention and treatment in school, private practice, hospitals, rehabilitation centers, nursing homes, etc., including our own USC Speech and Hearing Research Center.

Laboratories, Centers and Research Groups 

Aphasia Laboratory (Julius Fridriksson)

Work in the Aphasia Laboratory seeks to clarify the relationships between brain damage resulting from stroke and language impairment. Both advanced neuroimaging and behavioral techniques are employed.

Child Language Research Group

The Child Language Research Group represents the collaborative efforts of various departmental faculty whose diverse research interests share a common thread:  the commitment to better understand and improve the lives of preschool and school-age children who exhibit developmental problems in the areas of speaking, listening, reading, writing, and spelling.

KOOL2 | Knowledge of Orthographic Learning Laboratory (Kenn Apel)

The Knowledge of Orthographic Learning Lab (KOOL2) investigates factors that potentially affect the development of reading and writing. One major focus is on how children develop orthographic knowledge (i.e., knowledge regarding the systematic manner in which we represent spoken language in writing).

Language Processing Laboratory (Hiram McDade, Allen Montgomery)

The Language Processing Laboratory seeks to examine the mechanisms involved in the human response to the communication signal (auditory or visual). 

Neurolinguistics Laboratory (Dirk den Ouden)

The Neurolinguistics Lab studies the neural correlates of language processing and production. We are interested in the nature of language and linguistic representations, the extent to which language functions interact with other cognitive domains, the nature of language disorders and the role of neural plasticity in recovery from aphasia.

SCROLL: SC Research on Language and Literacy Laboratory (Suzanne Adlof)

The South Carolina Research on Language & Literacy Lab (SCROLL) conducts research that improves the early identification of language and reading difficulties in children and aids in the development of effective interventions for language and reading difficulties.

Speech Neuroscience Lab (Roozbeh Behroozmand)

The mission of our lab is to provide an integrated approach to the understanding of speech production and motor control mechanisms in the human brain. The ultimate goal of our research is to promote knowledge that can lead to the development of novel methods for diagnosis and treatment of speech motor disorders in patients with neurological deficits.

Speech Perception Laboratory (Dan Fogerty)

The Speech Perception Laboratory is directed by Dan Fogerty, Ph.D. Research projects in the laboratory seek to define how basic properties of speech contribute to speech understanding under a variety of complex and adverse listening conditions. We are particularly interested in how age, hearing loss, and cognitive function influence a listener’s ability to use these speech properties.

USC Speech and Hearing Research Center (Danielle Varnedoe)

The center provides a variety of diagnostic and treatment programs for individuals of all ages with communication disorders. We train future speech-language pathologists and researchers while providing our patients with the highest quality evaluation and treatment to improve social, educational and vocational participation. 

Written Language Laboratory (Krystal Werfel)

This mission of the Written Language Lab at the University of South Carolina is to increase educational and occupational opportunities for all individuals, particularly those with communication disorders.
