Biography

I am currently a postdoctoral fellow at Concordia Infant Research Laboratory. In August 2019, I graduated from the University of Hong Kong with a PhD in Speech and Hearing Sciences specializing in infant speech perception. My PhD thesis focused on the development of lexical tone perception in tone-learning infants. My main research interests are centered around infant language development and bilingualism. I am particularly interested in studying how differences in bilingual experiences (in terms of language environment) influence early language development.

On a side note, I am also multilingual. Growing up in Hong Kong, I speak Cantonese, English, and Mandarin Chinese; I also learned Japanese since teenage years.

Please feel free to contact me if you have any questions relating to my research.
