Sourav Das
I am a PhD student in Computer Science at UIUC,
working with Prof. Ling Ren on Applied Cryptography and Consensus Algorithms (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.
I am highly honored to receive the 2022 ChainLink Labs Ph.D. fellowship. I am also a finalist of the 2022 Meta (Facebook) Ph.D. fellowship.

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