I am currently a PhD candidate in linguistics at Nanyang Technological University, Singapore. A linguist with a professional background in data science, I study talk with a focus on understanding the interplay between social action and linguistic structure. I am also developing new tools for conversational (nontask-oriented) dialog systems. I have worked on annotations of non-lexical utterances, disfluency and laughter for the application in spoken language understanding (SLU). I have also worked on the development of cognitive grammars for conversational systems, i.e. framenets and constructicons.
My main research interest is the study of talk, combining qualitative studies of talk-in-interaction (interactional linguistics, conversation analysis) with the quantitative study of corpora of spoken discourse (grammar induction, distributional modeling). In my early-career research I have conducted linguistic fieldwork in different parts of Asia and built a video corpus of Malaysian Cantonese. Currently, I work on developing corpus-based representations of building blocks of conversation as tensors. Specifically, I explore how speech corpus data can be integrated in natural language understanding modules.
Most of my work has been on Chinese (Mandarin and Cantonese) and English (British Englishes and World Englishes).
