I am a Master's student in Artificial Intelligence at Sogang University, advised by Prof. Changjoo Nam. My research interests include multi-robot systems, path planning, and autonomous exploration. I did my Bachelor's degree in Software Convergence (Robot Vision track) at Kyung Hee University.

A schedule-guided framework that translates routing and scheduling solutions into task deadlines, robot task-type restrictions, and initial departure guidance for temporal search, without fixing complete robot tours.

This formulation provides a common geometric representation of safety across heterogeneous robots whileretaining their model-specific dynamics and admissible control constraints.

A decentralized budget-aware exploration framework for communication-free teams with directional sensing. Rather than exchanging maps, goals, or messages, each robot coordinates through its incidental observations.

Two-level approach in which the low-level is a sampling-based single-robot path planner, Safe Interval RRT* (SI-RRT*), that finds a collision-free spatio-temporal trajectory for an individual robot.
