About Me

I am Yiran Lei, a second-year Master student at Department of Computer Science and Technology, Tsinghua University, advised by Prof. Mingwei Xu. I received my B.Eng. degree in School of Software, Tsinghua University in 2020.

I am motivated to develop new mechanisms and algorithms in real network systems for finer measuring, controlling, and better network performance. My research interests include Network Telemetry and Programmable Data Planes. I worked closely with professor Vincent Liu.
