  • Title:Professor
  • Degree:Ph.D. & Habilitation in Language Sciences (University of Toulouse II)
  • Directed Research:Second Language Education
  • Research Field:Applied Linguistics (SLA, socio-psycholinguistics, corpus phonology, L2 French)


I hold a Habilitation (HDR) in Language Sciences from the University of Toulouse (France). After a Baccalauréat in Science, I studied Mathematics, Physics and Engineering before obtaining a BA in English studies, an MA in French Applied Linguistics and a PhD in Language Sciences with a focus on L2 speech education, psycholinguistics and phonology among Japanese learners of French. A full-time Lector at Salford University (UK), then an Adjunct Lecturer at Tokyo University of Foreign Studies (Japan), I got a tenured position as an Associate Professor (Maître de Conférences) in the Linguistics Department at the national University of Rouen (France), before joining Waseda University in 2009. In 2016, I received the Waseda Reseach Award for my High Impact Publication research activity. I specialize in Applied Linguistics (L2 speech education, corpus phonology, variation and corpus sociolinguistics), with a focus on French, Japanese and English. Co-director of the international research project (Inter)Phonology of Contemporary French (63 researchers, 41 universities, 26 countries), I co-edited several volumes (Paris, Oxford, Tokyo) on the varieties of spoken French in the world with the support of the French national agency for linguistic social and educational policies (DGLFLF), of which I have been appointed as a scientific expert member. Positioning myself at the interdisciplinary interface between cognitive and social sciences, I work with phonologists, phoneticians, psycholinguists, sociolinguists and computer scientists interested in linguistic policies, research methodologies and educational tools. My current research interests are: 1) Input and L2 speech learning; 2) Norms and variation in L2 speech learning; 3) French linguistic educational policies; 4) Plurilingualism and internationalization in higher education; 5) French-Japanese contrastive pragmatics; 6) Communicative handicap.
