Her research interest is language in interaction and multimodal analysis. She uses the methodology of Conversation Analysis, Interactional Linguistics and multimodal analysis in the study of everyday Mandarin talk-in-interaction. Her research explores how multimodal resources such as lexico-syntax, prosody and embodied actions are used by interactants in organizing turns, sequences and courses of actions in Mandarin conversation. The topic of multimodal organization of turns in Mandarin conversation is examined in her book Multimodality, Interaction, and Turn-taking in Mandarin Conversation (John Benjamins, 2014). Her recent work on multimodality in Chinese interaction is published in her co-edited book volume "Multimodality in Chinese Interaction" (Mouton, 2019).
