I am a Ph.D. student in H. Milton Stewart School of Industrial and Systems Engineering at Georgia Tech, advised by Rachel Cummings and Yajun Mei. Prior to Georgia Tech, I received my B.S. in Statistics at Peking University.

My research interests lie primarily at the intersection of differential privacy and statistical machine learning. My current focuses are on the the design of privacy-preserving algorithms for statistical machine learning models in the following three things: differentially private change-point detection, private online testing and false discovery rate control, and private modern collaborative learning.
