I am a PhD student in the Department of Computer Science and Engineering at the Indian Institute of Technology, Madras.

I am very fortunate to be advised by Prof. C. Pandu Rangan.

I am broadly interested in cryptography, social network security and blockchain technology. Currently, my focus lies on designing public key cryptographic primitives such as proxy re-encryption and exploring their applications to blockchain technology.

The Theoretical Computer Science lab is my academic home on campus.
