Biography

I am a senior undergraduate in Tsinghua, ranking top 5% in EE department and I am applying for graduate school this year. My research interests lie in topics in systems and networking such as cloud computing, software-defined network and crowd-sourcing. I enjoy working with brilliant people and contributing my intelligence and efforts to solving practical problems.

Currently I am a full time research intern at Microsoft Research with the legendary mentor Thomas Moscibroda, working on service scheduling algorithms in data centres. Last summer, I have spent a great time in US. First leading a crowdsourcing project in University of Notre Dame and then involved in a system project in CMU.
