I was born and grew up in Osaka, Japan, and since then have lived in Chicago (1999-2002), Tokyo (2003-2009, 2017, 2018), Cambridge (2010-2013, 2015-2017), Tübingen (2017-2018), and Birmingham (2013-2015, 2018-present). In my undergraduate study, I majored in English and studied second language acquisition (SLA), TEFL, and bilingualism, among other things. During my MA, I put a special emphasis on the use of corpora in TEFL research, and my master's dissertation was a corpus-based study on the comparison of English textbooks used in Asian countries. In my PhD research, I combined my interests in SLA and corpus linguistics. More specifically, I investigated the second language (L2) acquisition of English grammatical morphemes based on large-scale learner corpora and identified both systematicity and individuality in their accuracy development.

Prior to joining Birmingham in August 2018, I worked as a post-doctoral researcher at the Universities Â鶹¾«Ñ¡, Cambridge, and Tübingen. In Birmingham, I worked for the ESRC-funded project, ‘Interdisciplinary Research Discourse: the case of Global Environmental Change’, and was primarily responsible for the management, processing, and quantitative analysis of corpus data. In Cambridge, I was in the and investigated L2 development of linguistic complexity and accuracy. During my brief stay in Tübingen, I was in and the ICALL research group, where I deepened my knowledge in computational linguistic approaches to the analysis of learner language.

I have taught courses on statistics, R, corpus linguistics, and second language acquisition.

I am keen to supervise PhD research on topics at the interface between corpus linguistics (particularly learner corpus research) and second language acquisition. Please get in touch if you are interested in working with me.

My main research interests are in second language acquisition, corpus linguistics, and quantitative data analysis. I am particularly interested in systematicity and individuality in second language development. To characterize language development at the level of individual learners, it is essential to target a large number of learners, and for this reason, my work has exclusively drawn on large-scale learner corpora. To gain insights from such corpora, I have employed a variety of statistical and computational techniques.
