In Spring 2025, I am teaching a graduate course on topological data analysis. The GitHub repository is here: TDA Github 2025 

The Github repository for the Spring 2021 iteration is here: Topological Data Analysis GitHub 

Some lecture notes that I wrote for an undergraduate version of the course are available here: Preprint. (Updated 4/10/19) . These are under construction, and I eventually plan to edit and add to these notes to develop it into a more comprehensive undergraduate text. 

In frequently teach a course on Mathematics of Data Science. The GitHub page for Fall 2023 is here: Math for Data Science GitHub
