Research and Working Experience

  • 2012-presentResearch Assistant, Columbia University, Advisor: Junfeng Yang
    • Led research projects on reliability of concurrent software systems:
      • Morpheus, a concurrency testing framework for Erlang/Elixir using the effective randomized algorithms in [1].
        Open-sourced on https://github.com/xinhaoyuan/morpheus.
      • Partial Order Sampling [1], an effective randomized algorithm for concurrency testing that leverages dynamic partial order information to provably improve error-detection guarantees.
      • Txit [3], a framework to make lock-free data structures managable to verify by leveraging transactional memory.
    • Contributed significantly to other projects in the research group:
      • Shuffler [2], a practical code-reuse defense using continuous code re-randomization.
      • AppDoctor [4], a systematic testing tool that explores user interactions with android apps to find crash bugs.
  • 2017/05-2017/08Research Intern, Microsoft/Microsoft Research, Mentor: Suman Nath
    • Implemented the C/C++ orchestration of Torch, a framework for analyzing distributed systems and services.
  • 2016/01-2016/05Research Intern, Microsoft/Microsoft Research, Mentor: Cheng Huang
    • Applied systematic testing on Azure Storage system, and improve its reliability.
  • 2015/06-2015/08Research Intern, Microsoft Research, Mentor: Lidong Zhou
    • Designed and built a research prototype of DSoAP, a distributed computing platform specialized for social analytics.
  • 2009-2011Research Intern at System Research Group, Microsoft Research Asia, Mentor: Ming Wu
    • Implemented the TPC-C benchmark for Hyder [4] database system.
    • Awarded "Stars of Tomorrow" internship certificate for the excellent performance.
