Will Drewry is a Principal Software Engineer on the Payments team. His focus is on pragmatic privacy and security systems. His past applied research in software security led to widely adopted innovations in the field of consumer devices, from efficient, boot-time integrity measurement in all Android and Chrome OS devices (dm-verity, Verified Boot) to the broad adoption of hardware security modules, as well as creating an operating system security primitive used widely across Cloud computing: the use of Berkeley Packet Filters for system call boundary management (seccomp-bpf). He has also contributed across multiple standards and processor featuresets. Will joined Google in 2003 and received his B.A. in Computer Science from Boston University.
