I joined AT&T Labs, Research in September 2006 after finishing my Ph.D. in Computer Science at University of Maryland in August 2006. I received Bachelor's and Master's degrees in Computer Science from Seoul National University in 1996 and 2000. I am broadly interested in computer networks, cloud computing, large-scale systems, wireless networks, and mobile computing. Here are my publication list (updated June 2014) and curriculum vitae (updated June 2014).

The following is a list of specific areas that I have recently worked on.
  • Content Delivery
    A large fraction of today's Internet traffic is due to dissemination of various contents (e.g., videos). I have worked on a wide range of aspects in content delivery systems such as optimal content placement, efficient request routing, and efficient peer-to-peer media streaming.
    Selected papers:
  • Core Networks
    I have worked on topology and service path inference for wireless cellular services running on overlays of multiple wide-area networks. The work has become the foundation of a tool used by various cellular service operations groups in AT&T to identify relevant paths for service issue troubleshooting. I am also working on how to utilize SDN (software defined networking) approaches in wide-area network services.
    Selected papers:
  • Cloud Computing
    My research focus in this area has been on how to coordinate cloud and network infrastructure to enable efficient network-based services. I also have worked on designing VM allocation schemes, so that cloud service providers can efficiently allocate incoming VM requests to physical machines.
    Selected papers:

  • Wireless Networks
    My work in this area spans from wireless link layer to wireless routing. I have performed a detailed study of bit errors in the IEEE 802.11 link layer and proposed an efficient error recovery scheme based on the findings. I also have proposed efficient routing schemes and virtual routing backbone construction schemes in multi-hop settings.
