Su Yon Yim (PhD, University of Leeds) is Professor of English Education at the Chinju National University of Education in South Korea. She has been involved in diverse academic research that links real-world educational issues with theoretical insights. Her research interests are in the psychological aspects of language learning and teaching, focusing on language learning anxiety, motivation, and the emotions teachers experience. She has presented her work at major international conferences such as Asia TEFL and AILA, and contributes actively as a journal reviewer. Her recent projects examine the English learning experiences of North Korean defectors, the sociopragmatic challenges faced by pre-service teachers in situational writing, and how native-speakerism continues to shape teacher identity and self-efficacy. Drawing on both qualitative and mixed-methods approaches, she explores how language ideologies and teacher beliefs shape classroom practices. Her work reflects a sustained commitment to advancing English education through research that is both theoretically grounded and attuned to contextual realities.
