I am currently a postdoctoral fellow in the group led by Joonho Lee at Harvard University. Prior to this, I completed my Ph.D. thesis “Response Theory for the Matrix Product States in Frequency Space” under the supervision of Zhigang Shuai at Tsinghua University from 2018 to 2023.
My research focuses on the development of theoretical and computational methods to explore the quantum dynamics and electronic structure of correlated molecular systems. I specialize in tensor network techniques and auxiliary-field quantum Monte Carlo methods.
