Your Name

Liangwang Ruan (阮良旺)

or just call me Lian

Simulation Tech Lead at X Square Robot

I obtained my Ph.D. from the school of Computer Science, Peking University, supervised by Prof. Baoquan Chen, and was also a member of the VCL (Visual Computing and Learning) Lab. I obtained my Bachelor's degree in Computer Science from the Turing Class in Peking University. During my past research career, I focused on computer graphics with a specialization in physical simulation and optimization, and was honored to be advised by Dr. Bin Wang, Dr. Tiantian Liu, Prof. Bo Zhu, and Prof. Shinjiro Sueda. Currently I lead the simulation team at X Square Robot.

I have a blog in Chinese if you are interested.
