About

I am a Quantum Postdoctoral Fellow at the Simons Institute for the Theory of Computing at UC Berkeley, hosted by Umesh Vazirani. I got my PhD from Caltech in 2025, where I was fortunate to be advised by Thomas Vidick, Urmila Mahadev, and John Preskill. I participated in the 2025 EECS Rising Stars workshop at MIT.

I am broadly interested in quantum algorithms and quantum complexity, especially in understanding potential quantum advantage for solving problems in quantum many-body systems, like estimating ground energy and preparing ground states / Gibbs states. Those problems are central to quantum chemistry and condensed matter physics, with examples including the electronic structure problem. From a computer science perspective, problems on ground states and thermal states are quantum analogues of the energy minimization and classical Gibbs sampling, which play a fundamental role in complexity and algorithm design.

Feel free to contact me if you happen to be interested in similar questions, or just want to say hello :)
