I am an undergraduate student majoring in Biomedical Engineering and double majoring in Mathematics at Korea University. I previously conducted research as an intern at the Multimodal Interactive Intelligence Laboratory (MIIL), under the supervision of Prof. Paul Hongsuck Seo. My research interests lie in multimodal generative models, especially diffusion-based approaches for cross-modal alignment, synthesis, and understanding. I am currently focused on generative modeling in the video domain, exploring how temporal dynamics and multimodal signals can be jointly modeled within modern deep learning frameworks. Publications
