I was a postdoctoral fellow (mentored by Norman Y. Yao) at Department of Physics, Harvard University from 2022 to 2024. I was a postdoctoral associate (mentored by Aram W. Harrow) at the Center for Theoretical Physics, Massachusetts Institute of Technology from 2019 to 2022. I was a Resident at Microsoft Research AI from 2018 to 2019. I was a postdoctoral scholar (mentored by Xie Chen) at the Institute for Quantum Information and Matter, California Institute of Technology from 2015 to 2018. I received the Ph.D. degree (advised by Joel E. Moore) in physics from the University of California, Berkeley in 2015 and the B.Sc. degree in mathematics and physics from Tsinghua University in 2010. My research interests include quantum information theory, condensed matter theory, and machine learning.
