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 of Birmingham, 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 EF Education First Research Lab for Applied Language Learning and investigated L2 development of linguistic complexity and accuracy. During my brief stay in Tübingen, I was in LEAD Graduate School and Research Network and the ICALL research group, where I deepened my knowledge in computational linguistic approaches to the analysis of learner language.
