About

I am a Senior Researcher at ETRI (Electronics and Telecommunications Research Institute) and a concurrent Assistant Professor at UST (University of Science and Technology), South Korea. My research interests include LLM/VLM-based task planning, embodied AI, and human-robot interaction.

I received my Ph.D. in Electrical Engineering from KAIST (Korea Advanced Institute of Science and Technology), advised by Prof. Jong-Hwan Kim.
