Hi, there!

My name is Zixuan (Vicky) Lu. I am a second-year Ph.D. student at The University of Utah, Kahlert School of Computing, supervised by Prof. Yin Yang.

I received my M.Eng. degree from the Institute of Software, Chinese Academy of Sciences (ISCAS) in June 2024, co-advised by Prof. Xiaowei He, Prof. Xuehui Liu and Prof. Xueyang Zhu. Before that, I earned my B.Eng. in Theoretical and Applied Mechanics from the University of Chinese Academy of Sciences in July 2021.

My research interests are Physics-based Animation, High-performance GPU Computing, and numerical methods for Computer Graphics.

I am always open to discussions and collaborations — feel free to reach out anytime!
