Yvonne Tse Crepaldi is an Assistant Professor in the Department of Applied Linguistics at Xi’an Jiaotong-Liverpool University.  Her research explores language in interaction and multimodal communication, with a focus on family discourse and healthcare settings. Using Conversation Analysis, she investigates how young children develop language(s), cognition, and social competence through interactions with peers, siblings, and caregivers. She also conducts ethnographic research on family language policy (FLP) and its effects on multilingual development.

In healthcare communication, she has contributed to projects in urology and ophthalmology clinics in Singapore, as well as communication training for medical students. Her work examines doctor-patient interactions and family involvement in care. Currently, she is a member of the interdisciplinary Health Humanities Research Group at XJTLU.

Driven by a commitment to improving interpersonal relationships in familial and medical contexts, her research examines how interactional practices shape communication—and, in turn, relationships.

Beyond academia, she has industry experience in enterprise software and entrepreneurship, having founded startups in language and education services. She welcomes collaborations with health institutions and industry partners to advance communication research or disseminate evidence-based practices
