About Me

I am a researcher at Lightspeed Studios, Tencent America. I obtained Ph.D. from CSE, Washington University in St. Louis, where I studied computer graphics and geometric modeling under the supervision of Prof. Tao Ju. My PhD thesis focuses on injective mapping of triangular and tetrahedral meshes under constraints such as fixed boundary or positional handles. I also explored modeling shapes with sharp features and complex structures using multiple implicit functions. I am fortunate to collaborate with brilliant researchers at Adobe Research on many exciting problems in graphics and geometry.

I earned my master’s degree from Tsinghua University in 2018. There, I worked on high quality 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 (Physics) and a minor degree in Computer Science.
