Zhimin Fan
(pronounced as Chih-Min Fan; 范之闽 in Chinese)I'm a second-year master's student at Nanjing University, working with Prof. Jie Guo. I also work remotely with Prof. Ling-Qi Yan on various research projects. Prior to that, I received my bachelor's degree in Computer Science & Technology from Southeast University in 2023. I work on advanced path sampling techniques for light transport simulation. I'm always open to related collaborations.
I will graduate in June 2026 and am actively seeking a Ph.D. position for Fall 2026. Please contact me if interested!
