Research Interests
I'm interested broadly in security, privacy, and in theoretical and applied aspects of cryptography. On the applied side, of late, I've been dabbling in blockchains, and investigating how to apply cryptographic protocols to design blockchain-based applications (such as credit networks, blockchain rewrites, and more). On the theoretical side, my current work is on building tools for automated proof generation and verification of cryptographic protocols.
I'm always looking for new students! If you're an NMSU student and are interested in security, privacy, and/or cryptography (and can write decent code), please feel free to come talk to me, or drop me an email. We also have openings for undergrads!
My research is funded by the NSF and the Federal Aviation Administration (FAA). Thank-you to NSF and FAA for the support!

About me
Before I joined NMSU, I was an Assistant Professor from 2014-2017 at SUNY Polytechnic in Utica, NY. Before that I was a Postdoc in UNC Greensboro from 2011-2013, working with Steve Tate. I joined UNC Greensboro in July 2011 after completing my PhD at the University of North Texas's Department of Computer Science and Engineering in May 2011. At UNC Greensboro, I worked on this project. Downloadable source code and plugins related to the project can be found here Even before that, I received my BE in Computer Science and Engineering in 2003 from the University of Mumbai (Bombay).
I was born and raised in the beautiful city of Mumbai (Bombay).
