About Me

I am a Ph.D. student of Computer Science at MIT with a PhD minor in Mathematics, where I am a member of the Geometric Data Processing (GDP) Group, advised by Prof. Justin Solomon.

Research Interests

I am broadly interested in applying computing, mathematics, learning, and optimization to solving real-world problems. My previous works bridge visual/geometric computing and mathematics, specializing in designing algorithms to process, learn, and analyze manifolds, shapes, and surfaces.

Research Areas

Visual & Geometric Computing, Computer Vision, Graphics & Imaging, Applied Mathematics, Computational Physics, Partial Differential Equations (PDEs), Discrete & Computational Geometry, Inverse Problems & Optimal Control, Machine Learning, 3D Vision & Shape Analysis, Geometric Deep Learning, AI for Science & Data-driven PDE, Differentiable Programming, Physical Simulation, Robotics and Character Animation, Convex Optimization & Numerical Algorithms.
