Lawrence D. Shriberg, PhD, is Professor Emeritus of Communicative Sciences and Disorders, University of Wisconsin, Madison. He is Principal Investigator of the Phonology Project, Communicative and Cognitive Sciences Unit, Waisman Center, University of Wisconsin, Madison. Dr. Shriberg's research is centered on genetic and other origins of pediatric speech sound disorders. Goals of the research using a framework termed the Speech Disorders Classification System are to develop behavioral markers that can be used to identify biomarkers and explicate the causal pathways of pediatric speech sound disorders. Recent emphasis has been on children with speech motor delay and children with apraxia of speech.
Raymond D. Kent, PhD, is Professor Emeritus of Communicative Sciences and Disorders at the University of Wisconsin-Madison. He has authored or edited 19 books, including The Acoustic Analysis of Speech (with Charles Read), Reference Manual for Communicative Sciences and Disorders: Handbook of Voice Quality Measurement (with Martin J. Ball), The MIT Encyclopedia of Communication Disorders, and The Speech Sciences. He served as editor of the Journal of Speech and Hearing Research, associate founding editor of Clinical Linguistics and Phonetics, and associate editor of Folia Phoniatrica et Logopaedica. He currently conducts research on typical and atypical speech development with a clinical focus on children who have cerebral palsy or Down syndrome.
Tara McAllister, PhD, is Assistant Professor of Communicative Sciences and Disorders at New York University. She has published more than 30 peer-reviewed articles spanning the disciplines of linguistics and speech-language pathology. Her research aims to understand how articulatory and perceptual factors shape phonological development and disorders. She also directs the Biofeedback Intervention Technology for Speech (BITS) Lab at NYU, which develops and tests tools to provide visual biofeedback for persistent speech sound errors in children.
Jonathan L. Preston, PhD, is Associate Professor of Communication Sciences and Disorders at Syracuse University. He has coauthored more than 35 peer-reviewed publications, primarily focusing on phonetic, phonological, and neurobiological characteristics of children with speech sound disorders.
