About Me

I am a systems engineer at VolcanoArk （火山方舟） building large language model inference systems, with a focus on heterogeneous AI accelerators and efficient model serving.

Previously, I received my Ph.D. in Computer Science from Peking University. I was a member of the Center for Energy-efficient Computing and Applications (CECA), under the supervision of Prof. Chenren Xu. My doctoral research focused on transport-layer networking and interactive video streaming.
