About

I am a fifth-year Ph.D. candidate at the Embedded Systems and Computer Architecture Lab (eSCaL), School of Electrical and Electronic Engineering, Yonsei University, advised by Prof. Won Woo Ro.

My research interests and experience span the quantum software stack, including but not limited to:

• Quantum circuit simulation — accelerating state-vector and tensor-network simulation.
• Quantum chemistry algorithms — ADAPT-VQE and sample-based quantum diagonalization (SQD).
• Quantum error correction — code switching techniques and FTQC resource estimation.

Beyond Research

I street dance — popping since 2016, breaking since 2025. Day to day it feels like nothing moves, however much you drill. Then you watch footage of yourself from a year ago and it’s not even close. Research has felt much the same.
