Chaofan Lin (林超凡)

I'm a second-year Ph.D. student in Institute for Interdisciplinary Information Sciences (IIIS), Tsinghua University advised by Prof. Mingyu Gao. Previously I received my my B.Eng. in Computer Science from ACM Honors Class, Shanghai Jiao Tong University. advised by Prof. Yong Yu. During my undergraduate years, I had a wonderful time working with Yuqing Yang @ System Group of Microsoft Research Asia, focusing on LLM serving; and Tianqi Chen @ Apache TVM community, doing research on Deep Learning Compilers. Please check out my CV if interested. I go by `SiriusNEO` on most websites. And I usually use `Chaos` as a nickname (a variant of my real name). (Github | Zhihu | Scholar)
