John Ousterhout is Professor of Computer Science at Stanford University. His research addresses a wide range of topics related to infrastructure for building software systems, including distributed systems, operating systems, storage systems, development frameworks, and programming languages. His current research is in the area of granular computing: new software stack layers that allow the execution of large numbers of very small tasks (as short as a few microseconds) in a datacenter. His current projects are developing new techniques for thread management, network communication, and logging.
