the internet presence of kyle ormsby

Welcome! I am an associate professor of mathematics at Reed College; I also chair the department. My research lies at the interface of homotopy theory, algebraic geometry, and combinatorics. This year I am teaching Math 111 (calculus) and Math 201 (linear algebra) in the fall, and Math 113 (discrete structures) and Math 411 (topics in advanced analysis) in the spring. You can access my past teaching materials here. This site also contains my blog, and here is my CV, updated August 2024.

I believe that all of us have the ability and right to take joy in mathematics. Everybody counts.

The homotopy groups of $\mathrm{TMF}_0(5)$ are given by this $\delta^4$-periodic pattern.
