Bio

👋 I am a senior software engineer at Oracle Corp @ Redwood. I work on Linux core kernel, develop kernel diagnosis tools, and write Linux blogs.

I got my ECE Ph.D. from University of Southern California, advised by Ramesh Govindan and Barath Raghavan in Networked System Lab. My Ph.D. dissertation is about designing OS-level supports to achieve high-performance, scalable, and efficient cloud services. Prior to that, I spent four wonderful years at Peking University, graduating with B.S. degree in EECS and B.A. degree in Economics.
