About me

I am a PhD Candidate at the College of Information and Computer Sciences, University of Massachusetts, advised by Professor Cameron Musco. My work focuses on approximation of matrix methods using fast linear algebra and online learning with applications to real world problems. I am especially interested in the overarching goal of finding adaptive learning functions for large datasets.

Prior to this I worked as Visiting Researcher in Electronics and Communication Sciences Unit, Indian Statistical Institute, Kolkata with Professor Dipti Prasad Mukherjee. I completed my Masters in Computer Science in the year 2015, from the same institute. My primary research interest was in non-linear learning models for pre-image computation of image datasets.

In my leisure I enjoy playing guitar, badminton and birding. I am an ardent fan of absurdist fiction, philosophical fiction, epic fictions and graphic novels. I am absolute fan of Seinfeld and consider it the pinnacle of observational and conversational comedy.

I am on the job market for Summer/Fall 2023.
