Ziwei Zhu (朱子微)

Welcome!

I got my PhD in Computer Science at Columbia University in the city of New York. I am now working at Synopsys Inc. as a R&D Engineer for the development of optical design softwares such as DiffractMOD and FullWAVE .

I studied at Columbia Computer Graphics Group with Professor Changxi Zheng . Before joining Columbia, I did research on first-principle calculation with Professor Lai Wang , and computer animation with Professor Bin Wang at Tsinghua University. I was also fortunate to intern at Meta/Facebook Reality Labs. I am interested in PDE, GPU and AI for Science in general.

Education

Aug., 2018 ~ Feb. 2024, Columbia University, Doctor of Philosophy in Computer Science
Aug., 2014 ~ Jul., 2018, Tsinghua University, Bachelor of Science in Mathematics and Physics
