I am a research engineer at Suresoft Technologies. I received my M.S. in Artificial Intelligence from KAIST, where I was advised by Edward Choi.

My research focuses on benchmarking and evaluating large language models — including their robustness to linguistic variation, alignment with cultural and social values, and perception-level agreement with humans. I am broadly interested in how we measure and improve the trustworthiness of AI systems.
