Ronno Das

I am a fourth year PhD student at the University of Chicago, working with Benson Farb. I completed my masters and bachelors degrees at Chennai Mathematical Institute, India. My interests are in Geometry and Topology, specifically configuration spaces and other spaces of polynomials.

More details are in my complete CV.

most of my t-shirts are of my own design, though the jokes are often not original, collected in one place by popular demand
ask me if you want them in svg or with a transparent background
