Benjamin Ellis-Bloor

I am a graduate student in mathematics at Northwestern, advised by Ezra Getzler. I am interested in algebraic topology and algebraic geometry. Currently, I am thinking about cobordism and intersection theory on the moduli space of curves. I am on the job market in the 2026/27 academic year.

Here is my CV.
