playable.

We do not leave AI research on paper.
We build systems and games that can be run, played, and tested in the real world.

Education and Career

I completed a B.S. (2011.02) and M.S. (2013.02) in Mathematical Sciences at KAIST, and a Ph.D. (2017.08) in Electrical Engineering at KAIST. From September 2017 to April 2025, I worked as a Postdoctoral Researcher at KAIST Institute for Information Electronics Research (IIER). From May 2025 to February 28, 2026, I worked on game development at Sayberry Games. Since March 1, 2026, I serve as Assistant Professor at Daejeon University. I am co-developing Beasts of Ephesus, Floppy Survivors, and Hexagon Soup with Beff Inc. (SayBerry Games).

Current Focus

Core tracks are AI x Games Systems, trustworthy AI, and optimization-based decision making. Papers and implementation outputs are managed together to keep results reproducible and transferable.
