I am a research staff member at NEC Laboratories America, Inc., in the Mobile Communications and Networking (MCN) Research department. My research interests are in the areas of wireless networking, systems and mobile computing. Currently, I work on designing efficient algorithmic solutions as well as building experimental systems for broadband wireless access networks and WLANs/ WPANs. Of late, most of my works have been cross-layer oriented - operating at MAC and above, while leveraging PHY layer properties. Some of my recent projects can be broadly categorized under the following domains.
