About
Hi!I'm Hyeonbin.
I’m a Master’s student at KAIST AI, advised by Minjoon Seo. I’m also currently a research intern at KAIST STAI Lab, advised by Seongjoon Oh. I received my B.S. in CS from KAIST.
My research is motivated by a simple observation: language models often fail to generalize because they fit superficial patterns rather than learning how to reason. I design novel learning signals and strategies that push models toward more robust, transferable reasoning.
I’m always open to collaborations—feel free to reach out!
