I am an Assistant Professor in the Department of Mathematical Sciences at Durham University.

Previously I was an L. E. Dickson Instructor in the Department of Mathematics at the University of Chicago and a PhD student at Imperial College London under the supervision of Professor Toby Gee.

Here is my CV.

My email address is jack.g.shotton@durham.ac.uk.

I am interested in number theory and representation theory, especially in Galois representations and arithmetic properties of automorphic forms.

In 2023-2024 I will be offering two projects: Cyclotomic Polynomials at level III and Elliptic Curves at level IV.

Before coming to Durham I taught Introduction to Proof in Analysis and Linear Algebra, Honors Calculus, and Honors Basic Algebra at the University of Chicago.
