Professor; Department Chair

Communicative Sciences and Disorders


Maria Grigos is a Professor and Chair in the Department of Communicative Sciences and Disorders at New York University. Dr. Grigos also directs the Motor Speech Lab at NYU. Her scholarly work combines the use of perceptual, acoustic and kinematic methods to pursue two lines of research. The first centers on the study of speech motor control and motor learning across the lifespan. The second focuses on translational research where she studies the efficacy of motor-based intervention in childhood apraxia of speech (CAS). Research in the Motor Speech Lab is funded by the NIH National Institute on Deafness and Other Communication Disorders and the Once Upon a Time Foundation. Dr. Grigos holds clinical certification from the American Speech, Language and Hearing Association, and is licensed in speech-language pathology in New York State.
