I am an Assistant Professor in the Computer Science and Engineering Department at Seoul National University (SNU). My research interests broadly lie in operating systems and networked systems. My current research focuses on big data analytics, cloud computing, and mobile systems and security. One of the projects I’m currently working on is REEF, which is collaboration with Microsoft CISL.
Before joining SNU, I was a Principal Scientist at Microsoft. Before joining Microsoft, I led the systems research group at Yahoo! Research Silicon Valley for six months and worked as a Research Scientist for one and half years. My Yahoo! research projects include Mobius (data management platform for cloud-connected mobile apps) and workload-driven big data systems.
Before joining Yahoo! Research, I was a Research Scientist at Intel Research Berkeley from 2008 to 2011. I worked on CloneCloud, TaintDroid, and RouteBricks projects. Prior to that, I was a postdoctoral researcher at the International Computer Science Institute. I have a Ph.D. in Computer Science from the University of California, Berkeley, an M.S. in Computer Science from Stanford University, and a B.S. and an M.S. from the Electronic Engineering Department at Seoul National University.
During my Ph.D., I worked on trusted primitives for (Byzantine) fault tolerant systems (Attested Append-only Memory, Bonafide, which is my dissertation work), as well as peer-to-peer systems (Oceanstore, OpenDHT) and new Internet architectures (DONA).
I’ve been lucky to work with many smart people who are now affiliated with Apple, Brown University, Cisco, Cornell University, Duke University, Facebook, Georgia Institute of Technology, Google, Harvard University, HP Labs, Intel Labs, Microsoft, MIT, NC State University, Seoul National University, Technicolor, The Penn State University, Twitter, UC Berkeley, UCLA, UC Santa Barbara, University of Pennsylvania, University of Texas at Austin, University of Washington, VMWare, and Yahoo!.
I am looking for graduate and undergraduate students and postdoctoral researchers who are interested in doing research on big data, cloud, and mobile systems. If you are a highly motivated person who wants to build new systems, please email me.
