I’m Ben! My day job is Principal Techologist at Theorem, a financial technology startup, where I build machine learning models. When I’m not doing that, I also enjoy reading, making music, contra dancing, hiking, effective altruism, working on various projects, and many other strange activities. Here I write about some convex combination of math, computers, philosophy, effective altruism, and assorted miscellany.
