I am a Postdoctoral Associate in the Department of Computer Science at Yale University. I am working on distributed systems and system verification with Prof. Mahesh Balakrishnan and Prof. Zhong Shao. Besides my current projects, I'm interested in cloud storage systems, transactional storage systems, and datacenter network architectures. Before I came to Yale, I received my Ph.D. degree in Computer Science from Cornell University, Ithaca, NY, U.S.A., an M.S. degree in Computer Science from KAIST, Daejeon, South Korea, and a B.S. degree in Computer Science and Industrial Engineering with a minor in Electrical and Electronics Engineering from Yonsei Univerisity, Seoul, South Korea.
