I obtained my Ph.D. degree in 2016 from Carnegie Mellon University, under the supervision of Greg Ganger in the Parallel Data Lab. I was also very fortunate to work closely with Andy Pavlo in the Database Group. My research interest is in storage systems, database systems and cloud computing. Before coming to CMU, I received my bachelor's degree in Automation from Tsinghua University.
