I am a Robotics Ph.D. student at Cornell CS, advised by Prof. Kuan Fang. My research goal is to enable superhuman robotic abilities through advancements in representation, algorithm, and data collection.

I earned my bachelor’s degree from Seoul National University. During my undergraduate studies, I was fortunate to work with Prof. Jonghyun Choi, Prof. Hyounjin Kim, and Prof. Ayoung Kim.

I am always open to chat, so feel free to reach out!
