My name is emsenn. My given name is Morgan Sennhauser, but I publish and work as emsenn. My preferred honorific prefix is M., and I use they, them, and theirs as my pronouns.

I am an independent Lakota theorist, mathematician, and systems researcher. My work studies relationality: the way relating itself structures mathematics, knowledge, technology, governance, land, history, and life.

The shortest version is this:

I build formal languages for relations that existing fields do not know how to see.

Sometimes that produces mathematics. Sometimes it produces essays, specifications, curricula, software architectures, public research notes, or practical advice. The form changes. The work is consistent: I try to find the objects, relations, invariants, contradictions, dynamics, and failure modes that let a domain become thinkable on its own terms.

This website is the public record of that work.

Why this site exists

I work outside the normal institutional routes. I am not writing from a university department, corporate lab, foundation program, or formal research appointment. I am writing from lived experience as a Lakota land steward, public-web researcher, systems builder, and person trying to understand what becomes possible when relation is treated as primary.

That matters because much of the work here does not fit the containers people usually use to recognize serious thought.
