I am a postdoctoral researcher in the Institute for Data, Economics, Algorithms and Learning (IDEAL) at Northwestern University, hosted by Aravindan Vijayaraghavan. Before that, I obtained my Ph.D. in the Algorithms, Combinatorics, and Optimization program at Georgia Institute of Technology. I was 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.
