Networking Research Group
My interests are in building and analyzing networked systems.
Of late, I have worked on data center networks and big data analysis stacks.
I completed my PhD in Computer Science from MIT in 2008.

Speeding up Distributed Request-Response Workflows
MSR, Bing, UIUC, Steklov Math Inst.
We show how to improve the tail latency of datacenter services which are built as workflows over many components by appropriately allocating additional resources across the various stages in the workflow.
Also, even a small amount of incompleteness (i.e., returning partial results) can improve latency by a lot if used well.
Achieving High Utilization with Software-Driven WAN
MSR, Bing, GNS, UIUC
We show that given responsive networks and responsive applications
adapting who gets to send how much, when, and along which network paths can improve
network utilization without losing out on business priorities.
I've worked with some amazing interns at MSR.
