nice to meet you —

I'm Langdon.

I teach data science and computing at Boston University, and I believe two things stubbornly: that data speak louder than words, and that nobody should leave an intro course convinced they "aren't a numbers person." This site exists so that everything my students need — syllabi, datasets, policies, help — has one durable, findable home.

Everything else — my writing, research, projects, and the story of how I got here — lives on my main site.
