I joined AT&T Labs, Research in September 2006 after finishing my Ph.D. in Computer Science at University of Maryland, College Park 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, large-scale systems, wireless networks, and mobile computing.

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. For example, I have proposed optimal content placement and request routing schemes for content delivery network (CDN) providers and an efficient media streaming scheme in peer-to-peer settings.

  • Core Networks
    My work on topology inference and service path inference analyzes cellular service path built on an overlay of multiple backbones. 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.

  • 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.

  • Cloud Computing
    My current focus is on designing VM allocation schemes, which cloud service providers can use to allocate incoming VM requests to physical machines. I am also investigating various performace trade-offs arising when mobile computing and cloud computing infrastructure are integrated to support user applications.
