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.

I have delivered conference plenaries/keynotes and invited talks or workshops in different countries around the world, with previous or forthcoming events in Belgium, Canada, Denmark, Finland, France, Holland, Ireland, Israel, Japan, Thailand, UK, and US. In 2014, I delivered a 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.
