About

I am a second-year Master student at Carnegie Mellon University (CMU). I work with Prof. Zhihao Jia and Prof. Rashmi Vinayak on large-scale distributed LLM serving. My research interests span large-scale systems for LLM serving, KV-cache scheduling and ML compilers.

I was a Senior Software Engineer at ByteDance, where I worked on building large-scale scheduling systems for AI infrastructure. I received my Bachelor’s degree at Shanghai Jiao Tong University (SJTU) in 2022, where I worked with Prof. Shengyun Liu on distributed consensus protocols.
