I am a Postdoctoral Fellow at Ulsan National Institute of Science and Technology (UNIST) and in the Center for Flat Optics and Metaphotonics at Pohang University of Science and Technology (POSTECH), where I earned my Ph.D. in Mechanical Engineering in February 2026.

My research expertise lies in Electro-Mechano-Acoustic Transducers, Multiphysics Systems, Linear/Nonlinear Acoustics, and Acoustic Metamaterials.

I specialize in bridging the gap between theoretical models and practical applications, utilizing a workflow that integrates analytical modeling, finite element analysis, and rigorous experimental validation.
