Summary

Rockstar🎓
Top SchoolPatrice Godefroid is a Partner Software Engineer at Microsoft with a Ph.D. in Computer Science and a multi-decade track record in program analysis, software model checking, testing, verification and security. He helped pioneer practical software model checking (VeriSoft), partial-order reduction, and 3-valued abstractions, and co-developed influential tools like DART, SAGE (whitebox fuzzing credited with finding many Windows 7 vulnerabilities), and RESTler for stateful REST API fuzzing. His career spans Bell Labs, Microsoft Research (where he rose to Partner Researcher), and a recent leadership role as Distinguished Engineer co-founding Lacework’s Code Security team prior to its acquisition. Patrice combines deep theoretical foundations with pragmatic engineering that repeatedly turned research prototypes into production-grade fuzzing and testing services. He remains an active open-source contributor—improving RESTler’s robustness and features—bridging cutting-edge security research and real-world cloud service testing. His work is notable for both its academic impact and measurable operational results in finding and preventing critical vulnerabilities.
