ABOUT

Paul Hirschi

I build models that turn noisy data into decisions — and I write about the math that makes them trustworthy.

I'm a data scientist working across applied mathematics and statistics, from Bayesian methods and experimentation to the numerical guts of the algorithms everyone reaches for. Most of my work lives where a clean derivation meets a messy dataset.

This site is where I think out loud: posts that work through the math end to end, and a portfolio of engagements where that math moved a real number. If something here is useful, wrong, or worth arguing about, get in touch.
