# Todd Schiller

> Personal site of Todd Schiller, PhD — co-founder and CEO of PixieBrix. Writing focuses on software engineering, browser extensibility, programming languages, verification, AI coding, and applied reasoning.

Todd holds a PhD in software engineering and programming languages from the University of Washington (advised by Michael Ernst), and BS/MS degrees from Washington University in St. Louis. The blog spans both peer-reviewed research interests (verification, DSLs, machine learning) and practical engineering essays (debugging, testing, hiring, web automation).

Blog posts live under `/blog/{slug}.html`. Static pages live under `/pages/{slug}.html`. Interactive single-page artifacts (calculators, demos) live under `/artifacts/{slug}/`. For the full, current list of posts use the feeds below rather than caching any per-article list.
