I work in distributed systems and networking.  My research develops tools and techniques to support responsive, highly-available, and large-scale networked systems. I cultivated this research interest while doing my doctoral studies at Cornell Univeristy and my under-graduate studies at Indian Institute of Technology Madras. During my doctorate, I developed a framework based on mathematical optimization to judiciously tradeoff cost and performance in network services. This framework now supports three deployed infrastructure services: a safety-net for the DNS naming system (CoDoNS), a semi-open content distribution network (CobWeb), and a publish-subscribe system for RSS (Corona).
