A Brazilian category theory hub, from Ben Bumpus's group

Paulo Vitor Macedo Dias, a student of lab alumnus Benjamin Merlin Bumpus at the University of São Paulo, has built Categorias Brasil, which Ben describes as a repository for all things category theory in Brasil.

The site collects events, researchers, research labs, outreach material and research blogs in one place. Its main feature is a roster of category theory researchers, which is kept current and is deliberately broad. It includes pure category theorists and people applying categorical ideas in adjacent fields, students as well as established researchers, and Brasilians working abroad.

Anyone can register by opening a pull request or emailing categoriasbrasil@gmail.com with their name, affiliation, Lattes CV or website, and research areas. The site also takes blog posts, and encourages undergraduates to write introductory material.

Ben announced it on Merlin’s Notebook, a couple of months after taking up his professorship at USP.
