Hello, and welcome to The Bilingual Language Laboratory (BLL) at The University of Texas at Dallas (UT Dallas), directed by Dr. Raúl Rojas! Dr. Rojas is an Associate Professor in the School of Behavioral and Brain Sciences and a faculty affiliate at the Callier Center for Communication Disorders, and the Center for Children and Families.

The BLL is involved in several projects. Our main goal is to investigate dual language development in children who are in the process of acquiring a second language, including children who are typically developing as well as those affected by speech and or language impairments. The BLL is particularly interested in how the dual language skills of bilingual children dynamically grow and co-affect each other and related processing skills, as children get older.

Dual language development is not very well understood. Therefore, the more we know about the dynamic process of dual language acquisition, the more precisely we can inform the diagnostic and intervention approaches used with bilingual children that present with speech-language disorders. In addition, an expanded evidence base on dual language acquisition can facilitate valuable information to pertinent stakeholders including parents, teachers, clinicians, related professionals, and administrators.
