About Me

I am a fourth-year Ph.D. student at CSE, Washington University in St. Louis. I research computer graphics and geometric computing under the supervision of Prof. Tao Ju. I am interested in applying mathematics and computation to tackle challenging problems with a geometric flavor, with applications ranging from computer animation, geometric modeling to medical imaging.

I earned my master’s degree from Tsinghua University in 2018. There, I worked on remeshing with Prof. Hui Zhang and Prof. Dong-Ming Yan. I finished my undergraduate study in 2015 from Tsinghua University with a major in Material Science and a minor degree in Computer Science.

I have been collaborating with fantastic researchers at Adobe Research on many exciting problems in graphics and geometry.

In my spare time, I enjoy hiking, cooking Chinese food, reading books, and learning math.
