Bio | Research Interest | Publications


I am a Ph.D. candidate in the School of Computer Science at the Georgia Institute of Technology under the supervision of Professor Nick Feamster. I am broadly interested in computer networks and systems, but currently focus more on network configuration analysis, network reliability enhancement, and building better abstractions for network management.  I have received my B.S in Computer Science from University of Wisconsin - Madison and M.S from Georgia Tech. In the past, I have worked as a research engineer in Future Systems, which is a major manufacturer of network & security solutions in South Korea.

My Curriculum Vitae is here: CV (pdf)

Research Interest

My current research interest lies on analyzing network configuration methods and practices, and building better abstractions for managing networks using Software-Defined Networking (SDN). More specifically, I am interested in analyzing and modeling how current networks are configured and how they change over time. Based on such analysis, I enjoy designing and building better high-level abstractions, such as languages and platforms, for network operators or programmers to use when managing networked systems.


Kinetic is a domain specific language (DSL) and an SDN network control system that allows operators to express dynamic network policies in a concise, intuitive way. Using Kinetic, programmers can implement a network-wide control program that can dynamically change network behavior based on various types of network events.
