Ila Varma

I am an Assistant Professor at University of Toronto.

Previously, I was an Assistant Professor at UC San Diego. Before that, I was a NSF Postdoctoral Fellow at Columbia University and Harvard University. I received my Ph.D. in September 2015 at Princeton University under the advisement of Manjul Bhargava and Richard Taylor.

I'm mainly interested in:

Arithmetic statistics--in particular, asymptotics of class groups and number fields;

Galois representations and (p-adic) automorphic forms.
