Her research interests include the processes of learning to read, early literacy, and dyslexia. She has worked extensively on the Knowledge Sources theory of reading acquisition, which is unique insofar as it includes the teaching context, and the concept of lexicalised phonological recoding. She was the recipient of a Japanese Society for the Promotion of Science (JSPS) Invitation Fellowship, and is currently extending the Knowledge Sources theory with research on hiragana, a non-alphabetic orthography.
