Ram is here!

📢 I am on the job market in 2023-2024!

I am a sixth year PhD candidate at the University of Michigan Computer Science and Engineering department, where I am advised by Prof. Roya Ensafi. I am interested in using empirical methods to detect, analyze and prevent large-scale threats to the security and privacy of Internet users.

My research involves measuring Internet censorship and other forms of network interference at global scale. My research work has helped produce the Censored Planet Observatory, a remote measurement platform for the continuous monitoring of various types of network interference around the world. My work also involves understanding and analyzing the network technologies that enable censorship. I am the recipient of a FOCI Rising Star Recognition, an OTF Information Controls Fellowship, a Rackham Predoctoral Fellowship, and an IRTF Applied Networking Research Prize.

Previously, I was a research intern at Cloudflare Research and an OTF Senior ICFP Fellow in Information Controls at The Citizen Lab.
