Areas of Expertise

Puisan Wong is an Associate Professor in the Academic Unit of Human Communication, Development, and Information Sciences (CDIS) in the Faculty of Education at the University of Hong Kong. She received her doctoral degree from the City University of New York and was an Assistant Professor in the Department of Speech Communication Arts and Sciences at Brooklyn College of the City University of New York. Before joining the University of Hong Kong, she was a Research Scientist in the Department of Otolaryngology—Head and Neck Surgery at the Ohio State University. She holds the Certificate of Clinical Competence from the American Speech-Language-Hearing Association and practiced as a speech-language pathologist in special schools in New York.


Research Interests

Puisan Wong’s research aims at understanding factors that affect speech and language acquisition and developing effective teaching and intervention approaches to promote speech and language acquisition in monolingual and bilingual-speakers with and without communication disorders. 

Her current research projects include (1) Cantonese and Mandarin lexical tone acquisition in children with and without dyslexia, (2) Effective training for second-language speech sound acquisition, (3) prosodic effect on word learning in children with and without austism spectrum disorder, (4) tone and emotion processing in children with and without autism spectrum disorder, and (5) effective cues on word learning in young children with and without austism spectrum disorder.


Research Lab

Puisan Wong is the director of the Multimodal Speech-Language Research Lab, which houses 5 workstations, an Eyelink 1000 plus eyetracker, a sophisticated video recording system, the Observer XT behavior analysis software and a variety of hardware and software in a sound treated booth. The lab supports a range of speech perception and production research, and projects that examine audio- visual processing and integration, processing effort, and verbal and non-verbal communication.
