About

I am a first-year Ph.D. student in computer science (CS) at the University of Illinois Urbana–Champaign (UIUC), fortunately advised by Professor Hanghang Tong. Prior to this, I received an M.S. degree in CS at UIUC and a B.E. degree in operations research and a minor in statistics at Tsinghua University. My research interests lie broadly in machine learning (ML), with a current emphasis on the following topics:

  • Optimization: zeroth-order optimization, combinatorial optimization;
  • Graph ML: graph diffusion, graph optimal transport;
  • Trustworthy ML: robustness, fairness, imbalance;
  • Applications: time series analysis, recommender systems.
