Dr. Di Liu received his doctoral degree in Developmental Studies from Boston University with a concentration on Language and Literacy. His current research interests include the cross-linguistic comparison of prosody (commonly referred to as the music of language), the cognitive influence of L1 and L2 prosody, as well as technology-enhanced language learning. Dr. Liu’s most recent works explore teachers’ intonational pattern in Massive Open Online Course (MOOC), the cognitive load imposed by processing native and non-native speech, and the role of metalinguistic awareness and L1 in learners’ L2 prosody learning. Additionally, Dr. Liu has been working with Dr. Jonathan Barnes on an NSF funded research project investigating how tonal inventories of Mandarin and Cantonese affect intonation characteristics of the two languages.

Before joining Temple, Dr. Liu taught at Boston University Wheelock College of Education and Human Development. He has published widely and presented his works at both national and international conferences including TESOL, AAAL, PSLLT, and ALANZ. Dr. Liu has been serving on the board of the Washington Area Teaching English to Speakers of Other Languages (WATESOL) NNEST Caucus and has been invited to give webinars, talks, and workshops for pre-service and in-service teachers, and teacher trainers at various universities and organizations including Boston University, Virginia International University, and Howard Community College.
