Lee Hyun

I am an AI researcher at Samsung Advanced Institute of Technology (SAIT). I received an M.S. in EE from POSTECH advised by Prof. Tae-Hyun Oh.

My primary research focuses on generative models with multimodal LLM, spanning areas such as music generation, video reasoning, and speech-to-3D talking head generation.
Recently, I have been expanding my expertise toward LLM agents for materials discovery, focusing on LLM post-training and on how to build a reasoning trace from the materials design space to the target property space—and vice versa.
