[Google Scholar] [Curriculum Vitae]


I am a Ph.D. Candidate in Computer and Information Science at the University of Pennsylvania. I received the Master of Science in Engineering in Computer and Information Science at the University of Pennsylvania in 2013 and the Bachelor in Software Engineering at Northwestern Polytechnical University in 2011.

I am also the real-time scheduler (RTDS scheduler) maintainer for the open source Xen Project, which powers many commercial cloud computing platforms, such as Amazon Web Service.

I am the core contributor and maintainer for the research projects RT-Xen and CARTS tool
RT-Xen provides real-time performance guarantees for applications and virtual machines 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 the virtualization environment.

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

Research Interests

My research areas are real-time systems, virtualization systems, and cyber-physical systems. I am especially interested in designing, building, and analyzing timing-critical 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.
