I'm Nitin Chidambaram, a postdoc at the Max Planck Institute for Mathematics, Bonn working with Gaetan Borot . In July 2020, I defended my PhD at the University of Alberta where I was supervised by Vincent Bouchard and David Favero .

I'm broadly interested in algebraic geometry and what ideas from string theory can teach us about geometry. I've spent some time thinking about the Eynard-Orantin topological recursion in connection to enumerative geometry, and I'm currently trying to understand various contexts in which Airy structures produce physically and/or geometrically interesting invariants. I'm also interested in derived categories, especially in the context of the Bondal-Orlov conjecture on flops (i.e., the relationship to birational geometry), and I'm pursuing an approach to this conjecture using the notion of windows.

Other things I like to do

When I'm not doing math, I try to get outdoors as much as possible - climbing, skiing, or running for example. Recently, I've been learning to crack climb in Ettringen! Here are some pictures.
