Welcome to my webpage!
I am a graduate student at School of Technology and Computer Science, Tata Institute of Fundamental Research working under the supervision of Arkadev Chattopadhyay. I am broadly interested in theoretical computer science. In particular, I like thinking about various aspects of complexity theory (proof complexity, communication complexity, etc) and quantum computing. I am supported by a Google PhD Fellowship.
