Dr. Lukic has used functional and structural neuroimaging to identify selective brain regions with remarkably specific functions, including lexical retrieval, grammatical morphology, and word-order syntax. Dr. Lukic’s research also explores linguistic processes in the context of degeneration and development, from which investigating how language shapes cognition and emotions.

Dr. Lien’s research focuses on speech production and language development in children with cleft palates. Dr. Lien also studies early speech-language intervention for children with cleft palate.
