About

Hyeonbin Hwang

Ph.D. Student · KAIST STAI Lab

I’m a 1st-year Ph.D. student at KAIST STAI Lab, advised by Seongjoon Oh. I previously completed my Master’s at KAIST AI, where I was advised by Minjoon Seo. I received my B.S. in CS from KAIST.

My long-term goal is to build models that can learn beyond what human data can teach. I’m currently working on an agentic system for post-training, leveraging autonomous research agents and iterative harness optimization.

I’m always open to collaborations—feel free to reach out!
