Research

  • Topological data analysis (TDA), applied algebraic topology, computational topology, computational geometry, from GPS trajectory data.

My research primarily focuses on and . More specifically, I am interested in solving real-world problems using tools from and . In order to analyze large, complex, and noisy data, I develop provable and efficient techniques to find and classify significant geometric and topological features.
