About Me

I am currently a second-year PhD student at Dartmouth College. I am honored to be advised by Prof. Yaoqing Yang. Prior to this, I earned my Bachelor’s degree in Mathematics and Applied Mathematics from South China University of Technology in 2024. My primary research interests lie in learning theory 📊 and optimization 📈.


✨ Research Interests

I am interested in both classical learning theory problems (Rademacher Complexity, Covering Number, PAC-Bayesian, etc.) and recently emerging theory problems (primarily focusing on the statistical and optimization properties of large-scale deep neural networks). If you have any interesting related problems, feel free to discuss with me anytime! I am very open to cooperation.

My current research primarily focuses on:

  • Analyze the optimization properties (Non-Smoothness, Hessian, River-Valley, etc.) of large-scale neural networks, the behavior of optimization algorithms under specific loss landscapes, and develop scalable optimization algorithms based on these optimization properties and algorithms’ behavior.
  • Investigate non-vacuous and theoretically interpretable metrics for data/model statistical complexity in neural networks training, and determine how the interplay between data complexity and model complexity can lead to improved generalization and robustness performance.
