Research Interests

At the IDLE Lab, we empower learners to become confident, autonomous language users—across their lives, communities, and professions—in the post-AI era. In a landscape increasingly shaped by automation, we view learning as a continuous, human-centered journey—one that reaffirms curiosity, care, and creativity as essential to what makes us human. Our research explores how empathy and innovation can coexist to make digital learning more inclusive, equitable, and sustainable.

• Computer Assisted Language Learning (CALL)

  • Our CALL research focuses on co-designing human-centered, lifewide learning ecosystems with educators and industry partners. For example, we develop classroom frameworks that integrate Generative AI (GenAI) as a collaborative tool for storytelling, and create digital platforms that connect learners’ game-based experiences with reflective language tasks. We engage critically and creatively with GenAI to design environments where technology amplifies—not replaces—human connection. These ecosystems foster authentic communication, reflection, and growth, grounded in a deep understanding of learners’ needs, values, and lived realities. 

• Informal Digital Learning of English (IDLE)

  • Through IDLE, we examine how learners’ everyday digital practices—such as gaming, social media, and collaboration with humans or GenAI—enhance both language development and personal growth. We study how informal digital learning nurtures autonomy, motivation, and joy, bridging the gap between formal instruction and learners' lived digital worlds. These insights inform teacher education, curriculum design, and socially responsive pedagogy.

• Social Impact

  • Our work aims to create equitable and lasting impact through open-access tools and evidence-based frameworks that serve under-resourced, under-studied, and marginalized communities. We collaborate with schools, universities, NGOs, and governments to expand opportunities for learners to grow as lifelong and lifewide language users. Ultimately, we are prototyping a future where care, research, and technology converge—demonstrating how education can cultivate a more human, connected world within a rapidly evolving, post-AI landscape.
