Stefan Saroiu is a researcher at Microsoft, now in the Office of the CTO, Azure for Operators, and until 2020, at Microsoft Research. Stefan's research interests span many aspects of systems and networks although his most recent work focuses on systems security. Stefan's work has been published at top conferences in security, systems, networking, and mobile computing. Stefan takes his work beyond publishing results. With his colleagues at Microsoft, he designed and built (1) a methodology for testing cloud servers for the susceptibility to Rowhamer attacks, (2) Microsoft Embedded Social, a cloud service aimed at user engagement in mobile apps that has 20 million users, (3) the reference implementation of a software-based Trusted Platform Module (TPM) used in millions of smartphones and tablets, and (4) Zero-Effort Payments (ZEP), one of the first face recognition-based payment systems in the world.
Before joining Microsoft in 2008, Stefan spent three years as an Assistant Professor at the University of Toronto, and four months at Amazon.com as a visiting researcher where he worked on the early designs of their new shopping cart system (aka Dynamo). Stefan is an ACM Distinguished Member.
