About

I am a 1st-year M.S./Ph.D. student at Efficient Learning Lab (EffL), advised by Prof. Jaeho Lee at Pohang University of Science and Technology (POSTECH). I received my B.S. in Electrical Engineering from POSTECH in 2025.

My research focuses on identifying and addressing fundamental bottlenecks in robot foundation models (e.g., VLA and WAM) through principled algorithm design. My long-term goal is to bridge mathematical optimization and electrical engineering principles to enable ultra-efficient Physical AI.
