Hello! 👋 I am a Ph.D. student at KAIST advised by Prof. Tae-Kyun (T-K) Kim and Prof. Minhyuk Sung. I am currently visiting Meta Reality Labs as a research scientist intern, hosted by Dr. Jason Saragih. The goal of my research is to enable artificial intelligence to visually understand and simulate ourselves – humans – and our interactions with the environment. Lately, my focus has been on reconstructing and generating hand interactions, but my research interests are not limited to that. 🙂
