About me

I am a second-year Ph.D. student at KAIST Multimodal AI Lab, advised by Professor Joon Son Chung. My research focuses on multimodal AI, with a core emphasis on audio-visual speech and source separation. I investigate how cross-modal cues can be leveraged to isolate target signals and enhance auditory clarity in complex acoustic environments.
