Welcome to the Gray Matter Lab at San Francisco State University!

The goal of our work is to improve the quality of life for people with aphasia and their family and friends.                                                                                                                                          


  • Our mission is to lead the way in developing evidence based therapy methods for bilingual and multilingual populations with aphasia.
  • Our vision is that bilingual and multilingual populations with aphasia will receive the highest quality of therapy in order to increase communicative effectiveness and quality of life experiences.


Teresa Gray, Ph.D., CCC-SLP is the director of the Gray Matter Lab. Her research interests are focused on exploring the relationship between deficits in lexical access and control mechanisms, the effects of linguistic and non-linguistic treatments on control mechanisms, and improving the effectiveness of language intervention for bilingual populations with aphasia. Her clinical expertise includes assessing and providing language and executive function treatments for monolingual and bilingual populations with aphasia and traumatic brain injury.
