Louis Esser


I am an instructor in mathematics at Princeton University. I received my PhD at UCLA in 2023 under the supervision of Burt Totaro. Here is my CV.

My research interests are in algebraic geometry. Specifically, I am interested in equivariant birational geometry and optimization problems in algebraic geometry. I am a co-organizer of the Princeton Algebraic Geometry Seminar.
