About me

I am a Postdoctoral Researcher at the VGG, University of Oxford, working with Professor Andrew Zisserman. I completed my Ph.D. at KAIST under the supervision of Professor Joon Son Chung. I also earned my M.S. at KAIST, supervised by Professor In So Kweon. My research focuses on effectively training deep neural networks across multiple modalities (vision, audio, and text), and I am further interested in techniques related to sign language to support deaf communities.
