Byun Kang-Suk (변강석) is a pioneering South Korean Deaf scholar and linguist, recognized as the first Deaf individual in Korea to earn a PhD. in linguistics. His doctoral research focused on how signers of different sign languages establish mutual understanding, particularly through the process of cross-signing. He has also contributed significantly to the study of Korean Sign Language (KSL) corpus development and cross-linguistic interaction among sign language users.
Early Life and Education
Byun graduated from Seoul AeHwa School (a school serving Deaf students) in 2000. He then earned a Master's degree in Linguistics from Chungnam National University in 2012. In 2014, he moved to the Netherlands to pursue a Ph.D., deliberately choosing this path over more common destinations such as Gallaudet University in the United States, driven by his interest in pragmatics, conversation analysis, and cognitive science[1].
Doctoral Degree and Significance
On 22 June 2023, Byun Kang-Suk successfully defended his Ph.D. thesis at Radboud University, in association with the Max Planck Institute for Psycholinguistics. According to AbleNews, Byun became the first Deaf person to earn a Ph.D. in the field of sign language linguistics, both domestically and reportedly in the Netherlands[1][2]. The achievement is expected to catalyze major shifts in Deaf-led sign language research in Korea.
Academic and Research Contributions
Byun is currently a Visiting Professor at the Department of Sign Language Interpretation and Translation at Kangnam University, where he teaches and conducts research on Korean Sign Language (KSL), with a focus on corpus development and lexicographic resources, including KSL dictionary projects[1][3].
His doctoral research focused on intersubjectivity and cross-signing. He was affiliated with the Language and Cognition Department at the Max Planck Institute for Psycholinguistics, within Stephen Levinson’s lab, where he further developed his research in these areas[3].
Research Areas and Impact
Byun's research emphasizes how deaf individuals communicate successfully even without a shared sign language, focusing on the emergence of cross-signing as an improvised, ad hoc contact language, and examining conversational repair strategies[4]. His work integrates conversation analysis, cognitive linguistics, and sign language corpus development to shed light on intersubjectivity and communicative adaptation among Deaf communities.
Leadership
He founded the Deaf Academy (DeafKSLab) to support the nationwide Deaf academic community in Korea. As a notable example of this growth, at Kangnam University alone, there are 52 Master's and 9 Ph.D. scholars/graduates as of 2025. He leads this national network to foster academic excellence among Deaf researchers.
As the founder of 'SL-Dandelion' (수어민들레), he pioneered Korean Sign Language (KSL) literature, focusing on creative content production and mentoring aspiring sign language artists and creators.
