I consider myself as an investigator of human conduct in one's co-presence with others, the orderliness as well as the creativity of it, in real time, in its own terms. To conduct research of this sort, I am devoted to the perspectives/methods of two major sociology subfields, ethnomethodology and conversation analysis. One specific project I have been working on for long is the study of successive repairs in conversational interaction; that is, how people come to modify their own or another's talk more than once, how they do so, and what interactional import a series of repairs can bring out. A bunch of other projects I have in progress/mind include analyzing a set of telephone calls that occurred during the Shanghai lockdown due to Covid-19 in 2022, and how users of languages without gendered pronouns (e.g. Mandarin) recognize gender and deploy such pronouns in comparison with those with gendered pronouns (e.g. English).
