I have won a number of research grants and led various funded projects on test development, revision and validation around the world. My current projects include dyslexia and time extension in an online English test (Duolingo Competitive Research Grants), investigating the current accommodations available in IELTS (IELTS Joint-Funded Research Programme), and the CEFR-linking of the National English Adaptive Test in Uruguay.

My research can be found in the monograph, Task Equivalence in Speaking Tests (Peter Lang), and in chapters on validating dialogic speaking tests using function analysis (Task-Based Language Teaching and Assessment, 2021, Springer) and on examiner training of speaking tests delivered via video-conferencing (SiLT, forthcoming, CUP). I have published in international peer-reviewed journals such as Language Assessment Quarterly, Language Learning Journal and Assessing Writing.

I have co-authored encyclopaedic chapters on assessing speaking in the Routledge Handbook of Language Testing (2nd ed.) (pp.209-222) and the Routledge Handbook of Second Language Acquisition and Language Testing (pp.285-294).

Since 2014, I have published a popular, fortnightly column in the best-selling bilingual newspaper in Japan, The Japan Times Alpha, answering questions about the usage and history of English language posted from readers.

One of my main research interests lie in the assessment of L2 speaking and listening. I am particularly interested in the criterial features of learner language, the effects of task-related variables on learner language, and the roles of listening and note-taking skills in integrated speaking tasks. Other areas of my interest include test-taker characteristics and the effects of test accommodations on test-taker performance.

I have taught a number of undergraduate and postgraduate modules on language assessment, second language acquisition, research methods, statistical analyses, as well as on ESP (medicine and mechanical engineering) and pre- and in-sessional EAP. I also deliver workshops and short courses on language testing and statistical analyses for conferences and professionals.

I welcome proposals from prospective MA and PhD students who are interested in the assessment of L2 speaking and listening, as well as in other areas of language assessment. The topics of my past and current students include: assessing young learners at CEFR B2 level, the effects of task manipulation in an oral proficiency exam, orientations of native and non-native raters in a speaking test, and the effect of using different scoring methods for two versions of a reading test.

I have presented my research widely in conferences in the fields of applied linguistics and language testing, including the LTRC, EALTA, ALTE, LTF, TBLT, BC New Directions, BAAL TEA SIG and BAAL Annual Conferences. My future presentations are to appear in LTRC 2023 and BAAL TEA SIG Annual Conference 2023.
