I am a postdoctoral researcher at Georgia Institute of Technology, working in the Bhamla Lab with Prof. M. Saad Bhamla. My research lies at the intersection of bioinspired propulsion, vortex dynamics, fluid–structure interaction (FSI), and machine-learning-based flow diagnostics — aimed at decoding the fluid physics of biological locomotion and translating those principles into next-generation underwater vehicles, soft robots, and physical AI systems.
I earned my Ph.D. in Mechanical Engineering from Seoul National University (SNU) in 2022, advised by Prof. Hyungmin Park, and received the Best Ph.D. Thesis Award. I then joined Ajou University as a postdoctoral fellow with Prof. Daeshik Kang (2022–2023) before moving to Georgia Tech.
This work is supported by DARPA (Young Faculty Award) and the National Research Foundation of Korea (Sejong International Postdoctoral Fellowship).
