I'm a third year Ph.D. student in the LASR group of the department of computer science. My advisor is Prof. Mike Dahlin. My current interests are in distributed systems and fault tolerance.

I got my bachelor's degree (July 2005) and master's degree (Jan. 2008) in Computer Science from Tsinghua University.

    Research
  • Deterministic Execution of a multithread application: most consensus protocols require deterministic execution of the application, which is hard for a multithread program on a multicore machine, and previous solutions require hardware support or high runtime overhead. We're seeking speculative approaches to solve this problem. This project is undergoing.
  • UpRight: I was working on the UpRight project. It is a library and framework for building distributed systems with high availablity. The library can be configured to tolerate both crash failures and Byzantine failures. We've modified the Hadoop Distributed File System (HDFS) and Zookeeper coordination and lock service to use the UpRight library
  • Storage systems: Previously when I was a master student, I worked on serveral projects related to storage systems, including an adaptive caching system, a file system tracing tool and an out-of-band virtualization system.
