Summary
👤
Senior🎓
Top SchoolAdrien Champion is a Senior R&D Engineer with 11 years of experience specializing in formal methods and verification for safety-critical and embedded systems. Based in La Rochelle, he applies SMT solving, type-theoretic techniques and model checking to industrial-scale problems, and has contributed to tools like Kind 2 and hoice while bridging research and practice. A Rust advocate and trainer at OCamlPro, he designed and teaches a five-day "Mastering Rust" professional course and drives Rust adoption in verification workflows. His background spans postdoctoral and PhD work on k‑induction, invariant discovery and Horn-clause solving, and he brings hands-on experience integrating verification backends for languages and theorem provers such as Lean 4. Colleagues value him for turning deep theoretical results into usable toolchains and for an unusual combination of theorem-proving rigor with practical systems engineering.
