Projects & Extracurriculars

Math Formalization in Lean. Co-organizer of the weekly NYC Lean meetup. Author of a complete, sorry-free Lean 4 formalization of the classification of compact surfaces. Contributor to open-source formalization projects including Michael R. Douglas’s Jacobian Challenge, Rémy Degenne’s Brownian Motion, Mathlib’s manifold geometry library, and an ongoing formalization of Stokes’ Theorem. Author of Marathon, a human-driven autoformalization framework for Aristotle and Claude; maintainer of WikiLean, an AI-moderated, annotated mirror of WikiProject Mathematics for Mathlib declarations. Delivered the talk “4 Reasons You Should Care About Math Formalization” at Wikipedia Day 2026.
