About

I am a researcher at the Korea AI Safety Institute (AISI) within ETRI, working on explainable and robust deepfake detection. I received my Ph.D. in Electrical Engineering from KAIST in 2026, where I was advised by Prof. Junmo Kim (SIIT Lab), my M.S. in Artificial Intelligence from SKKU in 2021, where I was advised by Prof. Jae-Pil Heo (VC Lab), and my B.S. in Electrical Engineering from State University of New York (Buffalo) in 2019. During graduate studies, my research focused on dataset condensation, domain adaptation/generalization, and generative models.
