I am a Ph.D. candidate in Computer Science at Purdue University. My advisor is Prof. Elisa Bertino. I also work with Prof. Mikhail J. Atallah.

I have worked at Google, Mountain View as a Software Engineering Intern, and at IBM India Research Lab, Delhi as a Research Staff Member for about five years.

Doctoral Research

  • Areas: Information and database security, (secondary) software security.
  • Primary topic: How to authenticate trees and graphs without leaking.
  • Applications: Cloud computing, Database-as-a-Service, Services Computing, Privacy-preserving data mining, Secure XML distribution, Automatic data recovery.

Research Impact: (1) At IBM Research, I worked on "adaptation of pervasive applications" as part of the "Multi-Device Authoring Toolkit" (MDAT) project, which went into a product - IBM Websphere Everyplace Access Toolkit. (2) The notion of eliminatability paths and the E-path-PRE technique that I developed in my Master's thesis work at IIT Bombay has been the basis of at least two other Master's thesis, and has been incorporated in the LLVM compiler infrastructure of UIUC.
