Sourav Das

I am a PhD student in Computer Science at UIUC, working with Prof. Ling Ren on Applied Cryptography and Consensus Algorithms (aka Blockchain!).

I did my undergraduate studies from IIT Delhi, where I was advised by Prof. Vinay Ribeiro. After finishing my bachelors, I also had the fortune to visit National University of Singapore and IIT Bombay as a Research Assistant.

Research Interests

I'm broadly interested in Cryptography, Consensus Algorithms and Security. I have also worked on Scalability of Smart Contracts for permissionless blockchains.
