About Me

I am a fourth year PhD student in University of Waterloo CS theory group, advised by Sepehr Assadi. I transferred here from the Rutgers University theory group. I am interested in sublinear and streaming algorithms, online algorithms and more broadly optimization problems.

Previously, I was an undergraduate at IIT Madras where I worked with Jayalal Sarma. I also interned at Microsoft Research under Ravishankar Krishnaswamy.
