My name is Samir (Sam) Canning. I am an SNF Ambizione fellow at ETH Zürich in Rahul Pandharipande's group. In 2024, I was awarded the SwissMAP Junior Researcher Prize. I received my Ph.D from the Department of Mathematics at the University of California San Diego in June 2022, advised by Elham Izadi. Before that, I got my B.A. in mathematics at Columbia University. Here is my CV.

I work in algebraic geometry. I am interested in the intersection theory of moduli spaces, especially those related to the moduli spaces of curves, abelian varieties, and K3 surfaces.
