Research

My research interests focus on the discrete theories, computational algorithms, and practical applications of Geometric Analysis, with further interest in 3D Computer Vision:

1. Theories: Computational conformal geometry, quasiconformal Teichmüller theory, and Ricci flow

2. Algorithms: Shape analysis, mapping, registration, tracking, classification, and recognition

3. Applications: Computer vision, graphics, visualization, medical imaging, network, and geometric modeling
