About
Hi there! I am a founding engineer of RadixArk, a CS PhD student on leave, a proud member of lmsys.org, and a modest learner of RL systems. I live near Los Angeles with my girlfriend and two cats.
I feel honored to be part of SGLang team and coordinating our RL Group to facilitate large-scale RL. We are always welcoming self-motivated engineers and researchers to join us, and try our best to refer new opportunities.
I spent one year at UCLA, fortunately advised by Prof. Quanquan Gu, Dr. Ying Sheng and Dr. Lianmin Zheng.
I obtained my Bachelor's degree at Tsinghua University. At that time, I was supervised by Prof. Graham Neubig and Prof. Tongshuang Wu and mentored by Vijay Viswanathan at CMU. Their research guidance and tastes are invaluable to me.
