I have graduated! I will be joining Aster Data.

I graduated with a PhD from the University of California, San Diego in Spring, 2009. At UCSD, I was a member of the Systems and Networking group in the Computer Science department, where I was advised by Dr. Amin Vahdat. Prior to this, I was at the CSE department at Indian Institute of Technology, Kanpur.

Research Interests

My current research is focused around virtualization. I'm broadly interested in mechanisms for resource allocation, management and accounting in virtual machines, and the applications they enable.

Here is a copy of my dissertation, titled "Scalable Virtual Machine Multiplexing."

Mechanisms

• Time Dilation
• Difference Engine: sub-page granularity memory sharing.
• XenMon: ships with Xen by default.

Applications

• DieCast: how to test a 10,000 machine infrastructure realistically using only 1000 machines?
• Performance Isolation: how to make sure that co-located virtual machines don't adversely impact each others' performance?

Here is my list of publications as seen by DLBP. Accurate, but potentially not up to date.
