I am a Ph.D. student in AiSLab at SNU, supervised by Prof. Hyun Jong Yang. I earned my B.S. and M.S. degrees from POSTECH in 2022, 2025, repectively.
My research focuses on addressing the societal implications within the field of machine learning. Particularly, I am deeply engaged in exploring practical algorithms that provide robust assurances or compelling services to foster trustworthy machine learning and facilitate AI-mediated communication.
