Varun Madathil

I am currently a PhD student in the Department of Computer Science at North Carolina State University, and a member of the Wolfpack Privacy and Research Lab where I am advised by Dr. Alessandra Scafuro. I graduated with a Bachelor’s in Computer Science from BITS Pilani in 2016.

I am interested in cryptography. More specifically, I am interested in anonymity and privacy-preserving multiparty protocols and their applications to real-world systems like blockchains. Find my latest resume here
