I'm a research scientist in the Center for Computational Mathematics at the Flatiron Institute. I received my Ph.D. in statistics from the Department of Statistics at Stanford University in 2024, and my Bachelor's degree in mathematics from Tsinghua University in 2019. I will be joining the Department of Statistical Science at Duke University in July 2025. Here is my CV. |
