About me
I am currently a senior researcher in Interactive Geometry Lab, ETH Zurich, advised by Prof. Olga Sorkine-Hornung. I obtained my Ph.D degree in 2021 from VCC, KAUST, supervised by Prof. Peter Wonka and Prof. Maks Ovsjanikov. Before that, I obtained the MSc. degree from Oxford University, UK, and the BSc. degree from Zhejiang University, China. My research is mainly related to shape analysis, geometry processing and digital fabrication. I am also interested in computer graphics and computer vision in general.
You can find my full CV here.
