I am a Researcher in the Networking Research Group at Microsoft Research. I completed my undergraduate studies in Computer Science from IIT Kharagpur, India, and my Ph.D. in Computer Science from Cornell University in 2005. As part of my doctoral dissertation I developed VirtualWiFi, which is a virtualization architecture for wireless network cards.

I am organizing the MSR Cognitive Wireless Networking Summit in Snoqualmie, WA. More information can be found here.

Research (details here)
My research interests lie in the intersection of computer systems and networks. Currently, I am working on the following projects:

  • Cognitive Radios: Wireless networking over TV bands, variable channel width systems
  • Sherlock (Enterprise Network Management): Localizing failures in enterprise networks by analysing dependencies among services (web service, DNS, mail, etc) and the network elements (routers, switches)
  • WiFiProfiler: Peer-to-peer approach for helping users diagnose wireless failures without infrastructure support
  • DAIR (Dense Array of Inexpensive Radios): Helping IT administrators manage the enterprise WLAN by adding a wireless card to every desktop
  • In the recent past I have also worked on: VirtualWiFi, Cell2Notify, WiFiAds and Mesh.
