Brief Bio

I am a PhD student in the TCS group at The Institute of Mathematical Sciences. I am fortunate to be advised by Meena Mahajan. I am broadly interested in Theoretical Computer Science, and my current research interests are Query Complexity, Communication Complexity, and Sketching and Sampling Algorithms for problems in big data.

Previously, I obtained a Master's degree in Computer Science from IIT Kanpur advised by Prof. Surender Baswana and a Bachelor's degree in ECE from IIT BHU.
