You can find my official (and more regularly updated) homepage here.

I'm currently a second year Ph.D. student in the Computer Science department at Johns Hopkins University. I'm advised by  Abhishek Jain.

In 2016 I completed my masters in Computer Science at Indian Statistical Institute Kolkata, with Subhamoy Maitra as my thesis advisor. My undergraduate degree was in Computer Science and Engineering from National Institute of Technology Karnataka, Surathkal in the year 2014.

 My primary research interests lie in the various aspects of Cryptography. I am also interested in some other aspects of theoretical computer science.
