Research Scientist at GaloisInc
New York, New York, United States
Summary
🤩
RockstarLangston Barrett is a research scientist based in New York with 11 years of experience applying functional programming, formal methods, and security-minded engineering to systems and language tooling. He combines hands-on systems work—contributions to fuzzing frameworks like AFLplusplus/LibAFL and deployment automation for Mantl—with deep formal-proofs expertise in Coq projects such as Coq-HoTT and UniMath. His work spans low-level memory-safe fuzzing improvements, provenance and Datalog compiler enhancements in Soufflé, and developer ergonomics in tooling like Spacemacs, showing both breadth and precision. Langston frequently bridges research and production: he writes rigorous proofs and mathematical formalizations yet also scripts CI, Docker, and fuzzing pipelines to harden real-world software. An uncommon strength is his fluency moving between theorem proving and practical security testing, enabling novel approaches to dependable software.

UniMath/UniMath
Oct 2017 - Aug 2019
This coq library aims to formalize a substantial body of mathematics using the univalent point of view.
Role in this project:Back-end Developer
Back-end DeveloperContributions:274 commits, 87 PRs, 2 pushes in 1 year 9 months
Contributions summary:Langston formalized mathematical concepts using the Coq proof assistant within the UniMath library. They implemented core algebraic structures, specifically focusing on monoids, groups, and related concepts such as submonoids and subgroups, demonstrating an understanding of abstract algebra. Their contributions include defining and proving properties of essential structures, such as intersections, and extending algebraic definitions.
