tl;dr: I wrote Mooncake Transfer Engine.

I’m focusing on the research of in-memory distributed storage systems. Currently, I am working at the Mooncake team. I received my Ph.D degree from Tsinghua University in 2023 (supervised by Prof. Zuoning Chen and Yongwei Wu), and Bachelor degree from Xidian University in 2017.
