Bio


I'm a PhD student at the Sig Lab, the University of Pennsylvania, advised by Prof. Chenfanfu Jiang. My research interests include physically-based simulation and geometry processing.

I received my M.S. degree from the Department of Computer Science, the State University of New York at Stony Brook in 2020, and my B.S. degree from the Department of Mathematical Sciences, Tsinghua University (China) in 2017. Four undergraduate years of systematic education on mathematics developed my mathematical intuition while I was also attracted to computer science long ago (I taught myself programming at the age of 16). With love for both two subjects, I hope I can introduce mathematics to real life and make an impact on this world.

Projects


Surface Parameterization

It is a Computer Graphics course project. I implemented three kinds of parameterization algorithms: orbifold tutte embeddings, hyperbolic orbifold tutte embeddings, boundary first flattening. The first two solve a parameterization that can tessellate the whole Euclidean space or Hyperbolic space to form an orbifold structure. The third one embeds the boundary isometrically with given cone angles first and then extend to inner conformally.


Simple Ray Tracer

It is a simple CPU ray tracer. I followed the instructions in Ray Tracing in One Weekend to learn rendering. I did implement it in a weekend.


Infinitesimal Rigidity Checker

It is my undergraduate thesis. I turned the theory of infinitesimal rigidity into a program, which uses Hilbert-Einstein functional to decide whether a polyhedron is infinitesimally rigid and can visualize the basis of non-trivial infinitesimal motions of a polyhedron.
