Our Research

Nancy E. Hall is recognized for her expertise in fluency disorders and undergraduate research. Her areas of research include the relationship between language and fluency in early language acquisition in both typically developing children and those with communication disorders. Dr. Hall served on the ASHA Joint Coordinating Committee on Evidence Based Practice, and is a past editor of Perspectives in Fluency and Fluency Disorders, the peer-reviewed publication of ASHA’s Special Interest Division in Fluency and Fluency Disorders.


In-sop Kim’s research is in motor speech disorders, specifically in speech characteristics and treatment efficacy of people with apraxia of speech and Parkinson’s disease. Dr. Kim’s other interests focus on neurocognition, attention and language, and speech impairment in people with neurogenic disorders such as dementia, and cognitive processing in bilingual populations.

Associate Professor Allan B. Smith is interested in the acoustic measurement of speech in children, particularly children with speech, language, and reading disorders. Examples of his recent work are, “Durational characteristics of the first productions of trochaic and iambic novel words in children with speech delays,” in Clinical Linguistics & Phonetics, “Reduced speaking rate as an early indicator of reading disability” in American Journal of Speech-Language Pathology, and “A longitudinal study of speech timing in young children later found to have reading disability” in the Journal of Speech, Language, and Hearing Research.

Associate Professor Judy Perkins Walker’sresearch program explores prosodic deficits in adult subjects with right and left hemisphere damage. Dr. Walker is interested in the abilities of brain-damaged subjects to process and produce prosodic features that influence lexical access, syntactic parsing and the categorical assignment of questions and statements. Her research encompasses response time methodology and acoustic measurements of prosodic features. Her most recent publication, “The production of linguistic prosody by subjects with aphasia,” can be found in the Journal of Clinical Linguistics and Phonetics.
