Applied Linguistics combines research topics in the linguistics sciences and education to pursue principled approaches to language-related concerns. The Applied Linguistics PhD program at ASU is focused on simultaneous and developmental bilingualism in children and adolescents. Faculty participate in the program from within multiple curricular units across the institution’s four campuses. The program encourages interdisciplinary study, and its flexible requirements enable students to pursue those aspects of the disciplines that interest them the most. The program prepares students for entrance into the field as teachers, scholars and professionals.
