Ila Varma

I am an Assistant Professor at University of Toronto. I am currently a Sloan Research Fellow (2020 - present) and have been awarded the Connaught Research Fund (2021-present).

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:

UofT Mathematics Department's Equity Forum (website coming soon!)

UofTCensure - What did we achieve?

Day of Refusal to Demand Cops off Campus Resources

#ScholarStrike Resources

ShutdownSTEM Resources

Is this who we are, academia? - by Amanda Lehr and Tatiana McInnis
