# Rupert McCallum's Website

Welcome to my website. I am a post-doc at the University of Münster.

I am a research mathematician with interests in the theory of building, large cardinals, and geometric group theory.

I also take a strong interest in the philosophy of mathematics, physics and its philosophy, normative ethics, and meta-ethics. On previous occasions I gave a talk at the University of Sydney to students about to embark on animal research projects about the philosophy of animal rights. I'm extremely interested in the work Penelope Maddy in the philosophy of set theory and the work of Peter Koellner and Hugh Woodin in set theory and its philosophy. Here is my entry to Sam Harris' Moral Landscape essay competition.

Here is a draft of a new paper on the philosophy of large cardinals.

Here are some useful resources about effective altruism.
