About

Hi! I am a M.S./Ph.D integrated student advised by Professor Jaegul Choo at KAIST Graduate School of AI.
My research focuses on generative models, with particular interests in Image/Video Generation and Vision-Language-Action (VLA) models.

On going Project

I am a researcher at Davian Robotics, working on Vision-Language-Action (VLA). My research interests include video object insertion (VOI), with an emphasis on lighting consistency and dynamic object behavior.
