Hi, I'm Ju Seong (主聖). Every day, I reflect on these questions and love discussing them with others:

• In our rapidly changing world, does my research address the real needs and challenges of those around me and the broader community?
• Does my work improve lives in a way that's locally appropriate and sustainable?
• Can my research inspire educators, industry leaders, non-profits, and governments to develop innovative pedagogies, products, services, and policies that benefit society, especially the vulnerable and disadvantaged?

I created the Informal Digital Learning of English (IDLE) model, an innovative alternative to traditional classroom methods. My passion for IDLE was ignited during my volunteer work in 10+ countries over the past 25 years, shaping my commitment to informal and lifelong learning and educational equity. Our research community continually demonstrates IDLE's positive impact on students and teachers, expanding it to integrate AI and diverse contexts. Our team helps educators, schools, and industries integrate the IDLE model into their curriculums, practices, and services across 10+ regions. Since joining EdUHK in 2018, our research team has promoted global English learning through university-school-industry-government collaborations. Our main goal is to help learners enhance their English skills and access global opportunities. We believe that without genuine care, research loses its significance and becomes mere noise. Driven by this belief, we mentor students, work with like-minded individuals, and lead international and interdisciplinary projects in ways that are human-centric, locally appropriate, innovative, and sustainable.
