## John D. Wiltshire-Gordon

I have moved to Williams College! My new site is here: https://jwiltshiregordon.github.io/

I am a post-doctoral fellow at the University of Wisconsin, Madison working with Jordan Ellenberg. Fall of 2016 I was a post-doc at ICERM. I am applying for academic jobs, including tenure-track and second post-docs, starting Fall 2019. Here is my CV.

I study the representation theory of categories with applications in algebraic topology. I like configuration spaces, category theory, and computer algebra.

The prototypical situation: a category C acts on a collection of spaces X_c by transformations, and so the induced maps on homology form a C-module. My thesis, completed in 2016 at the University of Michigan under David Speyer, gives theory and algorithms for working with C-modules. I explain how to write a C-module using a presentation matrix and how to use that matrix to compute numbers associated to the module.
