I am a PhD student in Quantum Science and Engineering at Harvard University, where I am fortunate to be advised by Anurag Anshu, Sitan Chen, and Jordan Cotler. My doctoral research is also supported by the Kwanjeong Fellowship.

At Harvard, I am affiliated with the Harvard Quantum Initiative and the Theory of Computation Group. I am also a Junior Investigator at the NSF AI Institute for Artificial Intelligence and Fundamental Interactions (IAIFI).

I study the computational foundations of quantum many-body systems through the lens of theoretical computer science and mathematical physics. My work draws on techniques from computational complexity theory, statistical learning theory, random matrix theory, and low-dimensional topology to address fundamental problems in quantum information science.

Previously, I conducted research at Seoul National University through the Institute of Computer Technology and the Research Institute of Mathematics. I completed my undergraduate studies in Electrical and Electronic Engineering at Yonsei University with support from the Hyundai Motor CMK Scholarship.
