I am conducting research on the design and analysis of Large Scale Network
Systems. In particular, we are studying the structure and performance of overlays in the presence of selfish
users (see Selfish Neighbor Selection). In our initial work, we identified the causes and implications
of Mistreatment in distributed caching groups, and we designed a novel framework to mitigating mistreatment in
such groups (see Distributed Selfish Caching). In a parallel effort, we are designing scalable algorithms
for Service Deployment in the Internet-scale (see Distributed Facility Location). In collaboration with
colleagues from other disciplines, we developed a Large Deviations framework to rigorously identify, in real-time,
Network Anomalies by assessing deviations of empirical measures in large scale networks (see A Large Deviations
Approach to Network Anomaly Detection). In the past, we have studied the robustness of resource-reduced routers
in the presence of aggressive high speed transport protocols (see The Effect of Router Buffer Size on the
end-to-end Protocols Performance) and we designed distributed leader election mechanisms to prolong the
lifetime of heterogeneous wireless networks (see SEP: A Stable Election Protocol for clustered heterogeneous
wireless sensor networks).
