Helen Zhao is a Lecturer in Applied Linguistics in the School of Languages and Linguistics. She completed her PhD in Second Language Acquisition at Carnegie Mellon University. Her primary research focus is second language pedagogy on English grammatical structures. She has worked with several major grammatical systems including articles, prepositions, tense-aspect, and modality. Coming from a usage-based approach to language, she has done empirical research that explores the intricacy of acquiring these complex grammatical structures. She aims at making innovative use of educational technology to enhance students’ second language learning experiences.
