Her major research interests are in language development and natural language processing. Her research involves cross-linguistic comparison between Japanese and English. She is currently involved in collaborative research with the Research Institute of Logopedics and Phoniatrics, Faculty of Medicine at the University of Tokyo. She is interested in investigating the interaction between the factors children bring into the task of language development and the factors brought in by the specific structures of different languages and culture. She hopes to contribute a cross-cultural perspective to the Consortium.
