I'm on the job market! I will be graduating in Fall 2008, and I'm looking for (non-academic) full time research and development positions. If you have a matching opening, take a look at my resume.
I'm a PhD candidate at the University of California, San Diego. I'm a member of the Systems and Networking group in the Computer Science department, where I'm 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.
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?
