Portrait of William Blum

William Blum

Development Lead


I lead the engineering team on Project Springfield, a cloud service by Microsoft for finding security critical bugs in software. Springfield bundles a suite of security testing tools, including white-box fuzzing technologies from Microsoft Research as well as black-box fuzzing, and leverages the power of the Azure cloud to achieve scalability.

Prior to joining MSR I was in the Windows Compatibility team where I work on various projects including: static code analysis at scale, an automated root-cause analysis systems for Windows, Windows apps inventorying, and health predictive models for application compatibility.
