I’m an incoming M.S. student at KAIST's AMI (Advanced Machine Intelligence) Lab advised by Prof. Tae-Hyun Oh, and a recent KAIST graduate with a B.S. in Electrical Engineering and Computer Science (double major).

My current focus is grounding multimodal perception (vision/3D) and natural-language instructions into reliable long-horizon behavior for embodied agents.

  • B.S., Electrical Engineering & Computer Science (Double major)

• Hansung Science High School, Seoul, South Korea [Mar 2016 – Feb 2019]

• Research Intern, AMI lab @ KAIST SoC [Apr 2025 – Feb 2026] Advised by Prof. Tae-Hyun Oh

  • Built DarkEQA, a controlled benchmark that disentangles low-light exposure loss and sensor noise, enabling evaluation of VLMs on EQA-relevant perceptual primitives
  • Developing a depth-aware perception module for embodied agents (ongoing; planned submission in 2026)

• Research Intern, RIRO lab @ KAIST SoC [Dec 2023 – Feb 2025] Advised Prof. Daehyung Park

  • Fine-tuned a semantic segmentation model for KAIST campus navigation
  • Designed and implemented a scalable, multimodal ROS navigation planning architecture for Boston Dynamics' Spot, integrating Behavior Trees to improve reliability and robustness
  • Built an RViz plugin for waypoint navigation, streamlining the saving, visualization, and transmission of waypoints and routes to Behavior Trees, improving usability for robotic path planning
  • Analyzed move_base’s local navigation plugin by investigating the ROS navigation stack and optimizing parameters for the global_planner and dwa_local_planner; replaced the latter with a 3rd-party local trajectory generation module
