Welcome to my homepage!

I am a postdoctoral fellow at Colorado State University working with Dr. Rachel Pries.

I completed my Ph.D at University of Southern California under the supervision of Eric Friedlander and Sheldon Kamienny in May 2017. My research lies in the area of number theory and algebraic geometry. I am interested in torsion subgroups of elliptic curves, their Galois representations, Arboreal Galois representations, Fermat curves, Belyi maps and monodromy groups.
