Research Interests

My research interests are in the theoretical and algorithmic foundations of mathematical optimization, data science, and machine learning. More specifically, my current research focuses on six directions:

  • Provably efficient and robust non-convex algorithm for large-scale data analysis problems.
  • Fast and robust signal/image processing with incomplete and/or corrupted data.
  • Query- and computation-efficient methods for structure-aware zeroth-order optimization problems.
  • Efficient black-box adversarial attacks on neural-network-based classifiers.
  • Deep-learning augmented optimization for inverse problems.
  • Theoretical and computational foundations for modeling high-performance deep networks.
