About me

My name is Josh Holland, and I’m currently a PhD student at the University of Southampton. I am investigating ways to use the string diagrams of symmetric monoidal category theory to model systems of computation such as signal flow graphs and Petri nets. For a friendly introduction, see Graphical Linear Algebra, the blog run by my supervisor, Paweł Sobociński.

Before I started my PhD, I worked for Sirius, an independent IT contractor based in the South of England specialising in open source solutions, and prior to that I studied Mathematics at Keble College, Oxford as my undergraduate degree, culminating in an MMath.

You can get in touch with me via the social media links on the left, or by emailing me: josh@inv.alid.pw.
