​Research program

My research broadly addresses the pressing social-educational challenge of reducing language barriers and improving the oral communication skills of nonnative English speakers to foster their success in workplace and academic settings and promote their social integration. My research program centres on profiling the linguistic difficulties that most impede the production of comprehensible (clearly understandable) speech in adult second language learners of English so that these can be targeted in instruction and assessment. During my time at the University of Bristol, I founded the Second Language Speech Lab through EU funding (2012-16). I have also led consultancy projects, including a state-of-the-art review on automatic speech recognition and scoring for the British Council with concrete recommendations for test development. I have growing research interests in examining oral communication between carers and patients in healthcare settings and optimizing the recruitment of ethnic minority patients to health intervention studies.

Since completing my PhD in 2011, I have delivered conference plenaries and invited talks or workshops in different countries around the world, including Belgium, Canada, Denmark, Finland, France, Holland, Israel, and Thailand, and the UK. In 2014, I delivered a conference plenary at the Language Testing Research Colloquium in Amsterdam on the role of learner first language background in pronunciation assessment in relation to the theme, "towards a universal framework." The abstract synthesizes my research program on the comprehensibility construct.

Esteem indicators and professional service
I currently serve on the Editorial Board of Language Testing having previously served on the Editorial Boards of The Journal of Second Language Pronunciation and Language Assessment Quarterly.

​I also frequently serve as an ad-hoc reviewer. In addition to reviewing book proposals (e.g., Cambridge University Press, Bloomsbury), I have provided refereed reports for journals in the following research areas:
Second language acquisition - Language Learning, Studies in Second Language Acquisition, Canadian Modern Language Review 
Language teaching - ​Language Teaching, System, TESOL Quarterly, TESL Canada Journal 
Psycholinguistics - Applied Psycholinguistics, Bilingualism: Language and Cognition
Sociolinguistics - Applied Linguistics
Educational assessment - Assessment in Education: Principles, Policy & Practice
Speech sciences - Journal of Phonetics
Medicine - Trials

I am currently an elected Member-at-Large on the International Language Testing Association (ILTA) executive board and recently chaired the ILTA Best Article Award Committee (award citation). I am also an Expert Member of the European Association for Language Testing and Assessment (EALTA), a founding member of the Canadian Association of Language Assessment (CALA), and a member of the Medical Research Council Hubs for Trials Methodology Research (HTMR) Recruitment Working Group. I have acted as a peer-reviewer and rapporteur for Economic and Social Research Council (ESRC) grants, as an expert evaluator for Horizon 2020 European Commission fellowships (MSCA-IF-2017), and regularly serve on committees or panels for academic prizes in the fields of language testing (e.g., ILTA Robert Lado Memorial Award) and pronunciation (e.g., JSLP Best Paper Award). I recently reviewed the report and descriptors of phonology drafted by a working committee for the Council of Europe with likely policy and stakeholder implications. I have also conducted small-scale consultancy work with the British Council on automated assessment of speech and with a local National Health Service (NHS) Trust on analyzing simulated consultations in a pilot project for senior doctor training in hospital. I have been involved in capacity- and community-building as co-coordinator of the Bristol Centre for Assessment and Evaluation Research (2012-15) through organizing seminars, supporting research bids, seeking new funding sources, and stakeholder outreach and regularly serve in an assessment advisory role both locally and internationally.
