About

I'm Nitin Chidambaram, currently a Ramón y Cajal researcher (tenure-track) at the mathematics department of UNED in Madrid.

Before that, I spent 3 years as a postdoc at the University of Edinburgh and 2 years as a postdoc at the Max Planck Institute for Mathematics, Bonn. I graduated with a PhD in Mathematics from the University of Alberta in 2020.

I'm broadly interested in algebraic geometry and physical mathematics, and in particular what ideas from physics can teach us about geometry. Among other things, I think about the Eynard-Orantin topological recursion, Airy structures, integrable hierarchies, the moduli space of curves, vertex algebras and the relationships between them.

You can also take a look at my CV below for more information.

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. Here are some (older) pictures.

Sinster 7 finish line, 2019

Trail running

My first 100-mile race: Sinster 7 at Crowsnest Pass

Tromso

Ski touring

Somewhere around Tromsø, Norway

Climbing on Berneray

Rock climbing

Sea cliffs on Berneray in the Outer Hebrides (Thanks Nick for the picture!)
