Ph.D. Student in Computer Science · School of Interactive Computing, Georgia Institute of Technology
Advised by Prof. HyunJoo Oh & Prof. Sehoon Ha
I study motion as a computational medium across HCI and computer graphics. My research builds systems for designing, generating, and fabricating motion. I aim to make motion programmable and tangible across animated characters, mechanical artifacts, robotic systems, and AI-assisted creative tools.
Before starting my Ph.D., I spent eight years building software systems across AI systems, games, cloud platforms, and social robots.
