Prof. Guo’s primary research interest is grammatical development in English monolingual, Mandarin monollingual, and Mandarin-English bilingual children. Currently, he is evaluating longitudinal lexical and grammatical outcomes in Mandarin-speaking children with unilateral or bilateral cochlear implants. The goal is to identify malleable predictors of language development in children with hearing loss. Outside of the academic world, Prof. Guo stays active by running, swimming and trying to master the culinary arts.
