I am a researcher in the Systems and Networking group at Microsoft Research in Cambridge. Earlier I graduated from Cornell University where, with the complicity of my advisor Paul Francis, I indulged in follies like scalable routing and network management. Currently I am working on problems concerning datacenter networks and protocols.

Projects

• Predictable Data Centers (PDC)

In the past, I have worked on the following projects:

• Virtual Aggregation (ViAggre)
• Complexity Oblivious Network Management (CONMan)
• Proxy IP Anycast Service (PIAS)
• Forages into topics pertaining to network security such as DoS attacks, Prefix hijacks, etc.
