I am on the job market!
[CV]
My research lies at the intersection of security and networking and uses an empirical approach to study the complex ecosystems that make the Internet. I am primarily interested in understanding the form and function of the core Internet infrastructure and how attackers undermine the security and stability of the Internet. My research is supported by funding from Digicert, and Google. Previously, I worked on a range of things right from mobile computing, kernels, to next generation storage systems.
I work as a Postdoctoral Researcher with the Empirical Security Research Group in the CS Department at Stanford University with Zakir Durumeric. At UC San Diego, I had three(!) great advisors: Geoffrey Voelker, Stefan Savage, and KC Claffy. I also serve on the ICANN Security and Stability Advisory Committee (SSAC) which engages in ongoing threat assessment and risk analysis of the DNS ecosystem.

A New Look at DMCA Section 512 Process
This work focussed on the Digital Millenium Copyright Act and the potential "chilling effects" that might arise from the DMCA Section 512 process which allows copyright holders to take down content which they believe infringes their copyright. The goal driven was to enable a data-driven analysis of this extra-judicial takedown provision thereby enable recommendations that are primarily based in solid data. As a first step towards this goal, we establish a framework to begin understanding the takedown process and its effect on the Internet. [Report]SWAYAM CUBESAT Mission, COEP
Worked on a CUBESAT standard satellite "Swayam", that was launched by ISRO in June 2016. I worked on the design and implementation of the Onboard Computer and was part of the Systems Engineering group as well. [Link]Service
