I am a postdoctoral researcher in the AITA InnoCORE program, Department of Aerospace Engineering at KAIST, where I completed my Ph.D. under Prof. Hyochoong Bang — a dissertation honored with the KAIST College of Engineering Best Dissertation Award (2026). My work lives on the seam between data-driven methods and flight control — I design the estimators and controllers that keep aircraft flying when something goes wrong, and I care about taking them from theory all the way onto real flight hardware.

A large part of my research develops data-driven modeling and control. Using sparse identification (SINDy), the Koopman operator, and Gaussian-process methods, I learn vehicle dynamics from data and turn them into disturbance observers, model-predictive controllers, and adaptive laws. I apply these tools to fault detection, diagnosis, and fault-tolerant control for multirotors, eVTOL, and urban air mobility — systems where losing an actuator mid-flight is not an option.

More recently I work on navigation in GNSS-denied environments. When satellite signals are jammed or simply gone, a vehicle still has to answer one question: where am I? I fuse quantum magnetometers and magnetic-anomaly maps through factor graph optimization so aircraft can localize themselves without GPS — work that connects my control background to real quantum-sensing hardware.

Across all of this I try to close the loop between algorithm and airframe: redundant flight-control computers, hardware-in-the-loop testing, and flight campaigns on platforms from quadrotors to hoverbikes. I earned my B.S. at UNIST and my M.S. and Ph.D. at KAIST, with two years in between as a control engineer in industry.

I have authored 21 international journal articles and more than 70 conference papers, hold 5 patents, and have received over ten best-paper awards. You can read more about my work on the research and publications pages, or my full CV. I’m always glad to hear from people working on hard estimation, control, and navigation problems — feel free to reach out.
