I'm currently a researcher in the
Advanced Technology Group at
NetApp, Inc.
My research interests include operating systems, file systems, storage systems, and data management.
I was Ph.D. student in Computer Sciences at University of Wisconsin-Madison from August 2002 to August 2008. My Ph.D. advisors were Prof. Andrea C. Arpaci-Dusseau and Prof. Remzi H. Arpaci-Dusseau. My dissertation is titled "Characteristics, Impact, and Tolerance of Partial Disk Failures." |

December 2001. Available as: PDF InternshipsSummer Intern. Advanced Development Group, Network Appliance. Sunnyvale, CA. June - August, 2007. I analyzed the occurrence of silent data corruption in disk drives, identifying important characteristics that would be useful for corruption-proof system design. Summer Intern. Advanced Development Group, Network Appliance. Sunnyvale, CA. June - August, 2006. I analyzed data on latent sector errors (disk errors wherein a sector becomes inaccessible), examining the dependence on factors such as disk drive age and capacity, and identifying characteristics such as spatial and temporal locality. Summer Intern. Core Virtualization Research Group, Intel Corporation. Hillsboro, OR. May - August, 2005. I developed techniques for hypervisor-based fault injection and applied these techniques to study operating system behavior when memory and disk errors occur. Summer Intern. IBM T.J. Watson Research Center. Hawthorne, NY. May - August, 2004. I designed and implemented an extensible and scalable distributed cache architecture for an enterprise storage system. My scheme involved the use of remote memory (on machines over a high-speed LAN) for caching disk blocks. Summer Research Fellow. Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) Bangalore, India. May - June, 2001. I developed an instruction scheduler for a Java Just-in-Time compiler. The scheduler was built to utilize path profile information. |
