I am a sixth year PhD student at the University of Chicago, Department of Mathematics. My advisor is Benson Farb. I completed my masters and bachelors degrees at Chennai Mathematical Institute, India. I am a topologist, specifically interested in the topology of moduli spaces, in particular configuration spaces and spaces of maps.
More details are in my CV.
