Summary
👤
Senior🎓
Top SchoolBrian Belleville is a software engineer and Ph.D. candidate whose 13-year career blends applied security research and production systems engineering, currently building software at Google in Mountain View. His academic work at UC Irvine focuses on novel defenses against data-only memory corruption attacks—subtle exploits that evade control-flow integrity—reflecting deep expertise in systems security. He pairs that research background with practical JVM and Truffle experience, contributing performance and correctness improvements to the high-profile JRuby project. Prior roles span firmware validation at Western Digital and internships at Oracle Labs, Samsung Research America, and Matasano Security, showing a mix of low-level systems and applied security experience. Comfortable in both research and industry settings, he delivers pragmatic, security-minded engineering solutions that bridge theory and production. An unusual strength is his ability to reason about attacker-visible state (data-only vectors) while implementing JVM-level optimizations that improve real-world interpreter performance.
