I work on topics in systems and networking. My most recent research was about Community Information Management (CIM); that is, developing system support for data sharing and synchronization within loosely structured semi-trustful communities.  We built a platform that addresses practical problems affecting scale, security, and ubiquitous use of CIM.  Our platform offers the ability to replicate subsets of community data—suitably selected for each device; to perform updates anytime or anywhere at a fidelity native to the mobile or non-mobile device;  and to dis-allow or undo unauthorized changes to replicated data.

In addition to CIM, I am interested in other systems and networking topics as well, and have worked on research problems in the Domain Name System, mobile computing, network modeling, peer-to-peer systems, storage systems and wireless networks.  I developed these research interests while doing my doctoral studies at Cornell University and under-graduate studies at Indian Institute of Technology Madras.
