Biography

Mahadev Satyanarayanan is the Carnegie Group Professor of Computer Science at Carnegie Mellon University.  From May 2001 to May 2004 he served as the founding director of Intel Research Pittsburgh, one of four university-affiliated research labs established worldwide by Intel to create disruptive information technologies through its Open Collaborative Research model. He is a Fellow of the ACM and the IEEE, and was the founding Editor-in-Chief of IEEE Pervasive Computing.

As an experimental computer scientist, Satyanarayanan designs, implements, and evaluates systems. His research interests span mobile computing, pervasive computing and distributed systems (especially distributed file systems). Performance, availability, security, usability and manageability are some of the key attributes that he pays attention to in his work.

One outcome of Satyanarayanan's studies is the Coda File System, which supports disconnected and bandwidth-adaptive operation. Key ideas from Coda have been incorporated by Microsoft into the IntelliMirrorcomponent of Windows. Another outcome is Odyssey, a set of open-source operating system extensions for enabling mobile applications to adapt to variation in critical resources such as bandwidth and energy. Coda and Odyssey are building blocks in Project Aura, a research initiative at Carnegie Mellon to build a distraction-free ubiquitous computing environment. Earlier, Satyanarayanan was a principal architect and implementor of the Andrew File System (AFS), which was commercialized by IBM.

Education

Ph.D., Computer Science from Carnegie Mellon.

Bachelor's and Master's degrees from the Indian Institute of Technology, Madras.

Professional Background

Early in his career, Satya was a principal architect and implementor of the Andrew File System (AFS) which pioneered the use of scalable file caching, ACL-based security, and volume-based system administration for enterprise-scale information sharing. AFS was commercialized by IBM, is in widespread use today as OpenAFS, and has heavily influenced  the NFS v4  network file system protocol standard that was published in April 2003.
