Gregory J. Spray, Ph.D., CCC-SLP, was recently appointed as the Interim Graduate Program Director for the Department of Communicative Sciences & Disorders. Dr. Spray was previously a Postdoctoral Research Associate in the Spartan Stuttering Laboratory, which he joined after he completed his Doctor of Philosophy in Communicative Sciences & Disorders. Clinically, Dr. Spray has worked in a number of clinical settings to assess and treat individuals across the lifespan (ages 2-103): acute care, outpatient rehab, private practice (peds/adult), home care, and skilled nursing facilities. His therapeutic expertise lies in the areas of dysphagia, motor speech disorders, and cognition. 

Doctor of Philosophy: Michigan State University

Dr. Spray is currently the Past-President of the Michigan Speech-Language-Hearing Association (MSHA) where he served two-terms as President. He previously served as the MSHA Vice President for Membership, Member-at-Large for Students, and the Student Affairs Chairperson. He is an active member of the International Fluency Association (IFA) and serves on the Membership committee.

In spring 2017, he participated in the Erasmus+ Program where he studied at South West University in Blagoevgrad, Bulgaria, and also helped develop a medical speech-language pathology program with Prof. Dobrinka Georgieva, Ph.D. While completing his PhD program, Dr. Spray served on the MSU Presidential Search Committee, which led to the hiring of Michigan State University's 21st President, Dr. Samuel L. Stanley.

Research and Teaching

Key Research Interests:

Dr. Spray’s research interests include the neural basis of developmental stuttering that may help diagnose and predict persistent forms of stuttering. He is also interested in the neural basis of language development and disorders. He has published articles and presented posters in the areas of dyslexia, stuttering, and bilingualism.
