Research

• Research Groups/Areas: UCARE (research in Cloud Computing, Operating Systems, File/Storage Systems, and Distributed Systems) and UChicago Systems Group

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

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

• Program Committee:
      2014: SoCC, HotCloud, HPDC, MSST
