I am a Research Officer at the Agency for Defense Development, Korea's national defense R&D agency (akin to DARPA) and a First Lieutenant in the Republic of Korea Army. I received my B.S. from DGIST's Interdisciplinary Program, concentrating in Computer Science & Engineering.

Dynamics-Aware Policy Learning
We learn policies that model the underlying dynamics of an environment to forecast short-horizon. This look-ahead enables anticipatory behavior such as intercepting moving targets.
