I am a PhD Candidate in Computer and Information Science at University of Pennsylvania. I'm also the real-time scheduler (RTDS scheduler) maintainer for the open source Xen Project.
I received the Master of Science in Engineering in Computer and Information Science at University of Pennsylvania in May 2013 and the Bachelor in Software Engineering at Northwestern Polytechnical University in July 2011.

I'm the core contributor and maintainer for the research projects RT-Xen and CARTS tool
RT-Xen aims to provide real-time performance guarantee for applications in virtualization environment.
CARTS tool is a compositional analysis tool for real-time systems, which can be used to compute the real-time resource requirement for virtual machines in virtualization environment.

Beyond research, I also like to push my research findings to industrial product. As a result, I contributed the Real-Time Deferrable Server (RTDS) scheduler to Xen 4.5 

I was the Teaching Assistant for the following courses:
  • CIS553/TCOM512 Networked Systems Course in 2013 spring semester.
  • CIS541 /401  Embedded Software for Life-Critical Applications in 2013 fall semester and 2014 fall semester.

Possible RA position in PRECISE lab:
If you are a Penn student and you want to do some system work (such as implement/upstream new features for Linux/Xen or implement an embedded systems) in our lab, please don't hesitate to send me an email (with your CV). Our lab may have a position for you. 


Research Interests:

Cache management and analysis, cyber physical systems, real-time virtualization,  real-time systems, embedded systems.

    I like playing badminton. I am currently a member of the competitive team at Penn Badminton Club. I was in our college's non-professional badminton team for four years in undergraduate. Our team won the third place twice among 16 colleges and I played for singles men and doubles men. 
    I am also into the group exercise at Penn's gym. 
    I also like other sports, such as table tennis, and the outdoor activities, such as hiking.
