Yan Yu

Associate Professor
Ph.D., City University of New York, Graduate CenterM.A.,St. John’s UniversityB.A., Hubei Normal University, China

Yan Yu uses an interdisciplinary approach to examine brain plasticity for auditory and cognitive (language and music) processing in both neurotypical and neurologically impaired populations. In particular, Yu focuses on how experience (language and music) interact with brain development, and what’s the brain’s malleability in response to neurointervention. Yu’s research incorporates approaches from several disciplines spanning from communication sciences and disorders, psycholinguistics, neurolinguistics and neurointervention.  

Dr. Yu is an American-Speech and Language Association certified speech-language pathologist. Dr. Yu’s clinical expertise lies in the area of typical and atypical language development in both monolingual and bilingual children including children with autism spectrum disorders and other developmental disorders.
