I am currently recruiting graduate students and uchicago undergrads.
Please contact me if you are interested in my research projects.

Research

  • Research Groups: UCARE, CERES, and UChicago Systems

  • Research Areas: Cloud/Distributed Computing, Operating Systems, and File/Storage Systems

  • Research Interests: The world's data is growing tremendously. My research group helps today's data storage systems meet high performance and reliability demands. Specifically, we (1) build reliable cloud storage that manages complex hardware failures, (2) redesign OS-level file systems to better support modern cloud software infrastructure, and (3) explore new storage technology architectures.

  • Students: Thanh Do, Tanakorn Leesatapornwongsa, Tiratat (Knot) Patana-anake, Riza Suminto, and more

  • Program Committee:
        2015: FAST, ASPLOS**,
        2014: SoCC, HotCloud, HPDC, MSST, INFLOW
        2013: SoCC, VLDB
        2012: VLDB, MSST, NAS
        2011-2010: PDSW, DBTest
        ** External Review Committee (ERC)
