Liangsheng Yin 「尹良升」

Hello, my name is Liangsheng Yin, and I got my bachelor degree at Shanghai Jiao Tong University, majoring in Computer Science, in ACM Honor Class. I am also a incoming Ph.D. student at UC Berkeley,

Currently, I am fortunate to work with Lianmin Zheng and Ying Sheng from LMSYS.ORG, working as a core developer of SGLang, and avised by Ion Stoica and Joseph E. Gonzalez in Sky Computing. We are committed to developing more efficient and powerful system for Artificial Intelligence. I am also an applicant for the 2025 Fall Ph.D. program in Computer Science.

Feel free to check out my CV and drop me an e-mail if you want to chat with me!
