Ph.D. student in Quantum Science and Engineering at Princeton University, working on quantum information theory, quantum many-body dynamics, quantum algorithms, open quantum systems, and physics-inspired machine learning theory.

I am a Ph.D. student in Quantum Science and Engineering at Princeton University. My research is centered on quantum information theory and quantum many-body dynamics, with additional interests in quantum algorithms, open quantum systems, and physics-inspired machine learning theory.

Research

I work on problems at the interface of quantum information, condensed matter theory, and nonequilibrium many-body physics. Recent projects have focused on non-Hermitian quantum systems, non-Bloch band theory, parity-time symmetry breaking, and the role of geometry in open-system dynamics. More broadly, I am interested in entanglement and complexity in many-body systems, randomized quantum evolution, and theoretical questions that connect quantum science to modern machine learning.

My recent research experience includes non-Hermitian quantum systems and topology, especially the skin effect in two and higher dimensions, the interplay between parity-time symmetry and exceptional points, and related experimental collaborations. I have also worked on many-body dynamics and entanglement phenomena, including randomized quantum evolution, operator growth, and quantum-information perspectives on quantum gravity.

Spare time

I enjoy photography, calligraphy, Japanese rock music, and various sports.
