My research brings together second language writing, Dynamic Assessment, and human–AI interaction to examine how learners move from mediated performance toward independent control.

How does mediated interaction make second language development visible?
I study second language writing development through mediated interaction, drawing on discourse, classroom, and computational data.
My research agenda started with discourse and interaction, then moved toward AI-mediated approaches grounded in developmental theory.
Agency, identity, peer interaction, and online or hybrid participation
Dynamic Assessment, syntactic complexity, and generative tools as mediators
Customized AI, genre-sensitive mediation, and L1 transfer
Collaborative coding, embeddings, and interpretable computational analysis
Genre-sensitive assessment, mediation, and L2 rhetorical growth
This work examines how mediated interaction can support and reveal developing rhetorical and linguistic abilities in L2 writing. It brings together Dynamic Assessment, genre, instructed development, and cross-linguistic influence.

This line of research asks how pedagogical goals, learning theory, and technical design can be aligned so that AI supports writers’ reasoning rather than simply improving the immediate text.

Selected roles show the research work behind my agenda, from classroom-interaction analysis and technology mapping to independently led human–AI inquiry.
Designed and validated a grant-funded human–AI collaborative workflow for coding EFL writing dialogues, then presented the findings and prepared the resulting manuscript.
Led data analysis, manuscript preparation, and revision for a first-authored study on AI-assisted approaches to making L1 transfer visible in EFL writing.
Catalogued technology-assisted language-learning tools and coordinated pedagogy workshops connecting international scholars in applied linguistics and generative AI.
Transcribed classroom interaction and conducted interviews, then carried out qualitative coding, thematic analysis, and complementary quantitative analysis of longitudinal data.

How can instruction support learners without doing the thinking for them?
Through dialogue and graduated mediation, I help students move from supported to independent work.
