I am Santhoshini, a first year theoretical computer science (TCS) PhD student at Harvard University. I am very fortunate to be advised by Prof. Madhu Sudan. In the past, I have worked on streaming algorithms, problems in arithmetic complexity, data structures and cryptography. My current research interests are broad and span various topics in TCS including complexity theory, coding theory and game theory. In my leisure, I enjoy solving math puzzles, most of which I take from past IMO papers, and reading fantasy novels.
