Patrice Godefroid is a Principal Researcher at Microsoft Research. He received a B.S. degree in Electrical Engineering (Computer Science elective) and a Ph.D. degree in Computer Science from the University of Liege, Belgium, in 1989 and 1994 respectively. From 1994 to 2006, he worked at Bell Laboratories (part of Lucent Technologies), where he was promoted to "distinguished member of technical staff" in 2001. His research interests include program (mostly software) specification, analysis, testing and verification. Dr. Godefroid is probably best known for his pioneering work on partial-order reduction for model checking concurrent systems (his PhD thesis is published as LNCS volume 1032 by Springer), for his work on VeriSoft, the first software model checker for mainstream programming languages such as C and C++, for his work on 3-valued model checking with may/must abstractions for sound program verification and falsification, and for his work on automatic test generation with DART. More recently, he co-developed SAGE, the first whitebox fuzzer for security testing, which was credited to have found roughly one third of all the security vulnerabilities discovered by file fuzzing during the development of Microsoft's Windows 7.
