Euijin Jeong

I'm an AI researcher at RLLAB Yonsei, advised by Professor Youngwoon Lee. My goal is to build highly intelligent agents that, like humans, perceive raw signals, act in the world, and keep learning throughout their lifetime. My research centers on foundational action models, meta-RL, and continual learning.
