Lena V. Kremin

PhD Candidate

Concordia University


I am currently a PhD candidate in Psychology at Concordia University in Montreal, Canada.

My main research interest is language acquisition in bilingual children, particularly how bilingual infants separate their languages. I’m currently involved in projects investigating parental language mixing, word learning, and the potential effects of mispronunciation on comprehension.

Outside of my research, I enjoy practicing and teaching yoga, travelling, spending time with my dog, and occassionally knitting.

Please do not hesitate to contact me if you have any questions relating to my research.
