Biography


I am a first-year PhD student in Stanford. Before that I was an undergraduate in Tsinghua, ranking top 5% in EE department. I used to intern at Microsoft Research Asia working on cluster service scheduling with high fault-tolerance. 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.

I enjoy working with brilliant people and contributing my intelligence and efforts to solving practical problems with impacts.

Research


Microsoft Research Asia
11/2012 - Present
Full time intern
Project: Data Center Service Management
  • Explored and developed highly efficient and fault-tolerant algorithms for intra-cluster service scheduling as well as an event-driven simulator for testing
  • New algorithm achieved 10% average utilization increase and was adopted by Microsoft Azure
  • SCION Group, CyLab, Carnegie Mellon University
    8/2012 - 9/2012
    Summer intern
    Project: Path Joining Problem in SCION Network
  • Worked on SCION prototyping system and gateway implementation
  • Proposed and implemented an algorithm for SCION intra-TD path joining where a new data structure was designed to support shortest-path search in low computation complexity
  • Dept. of Computer Science and Engineering, University of Notre Dame
    6/2012 - 8/2012
    Summer intern
    Project: Crowd-sourcing for Urgent Human Computing
  • Independently built an automatic crowd-sourcing system on Amazon Mechanical Turk
  • On-line experiments successfully attracted 271 participators from more than 10 countries. Results showed the feasibility of sourcing engineering tasks to on-line workers
