I am a Ph.D. candidate in the Algorithms, Combinatorics, and Optimization program at Georgia Institute of Technology. I am fortunate to be advised by Santosh Vempala. I received my B.Sc. in Computer Science and Mathematics at Hong Kong University of Science and Technology in 2018. You can find my CV here.
My research focuses on robust statistics, machine learning theory and high-dimensional learning.
