American computer scientist (born 1966)
Sanjay Ghemawat (born 1966 in
West Lafayette, Indiana )
[1] is an
Indian American
[2]
computer scientist and
software engineer . He is currently a Senior
Fellow at
Google in the Systems Infrastructure Group.
[3]
[4] Ghemawat's work at Google, much of it in close collaboration with
Jeff Dean ,
[5] has included
big data processing model
MapReduce , the
Google File System , and databases
Bigtable and
Spanner .
Wired have described him as one of the "most important software engineers of the internet age".
[5]
Ghemawat was elected as a member into the
National Academy of Engineering in 2009 for contributions to the science and engineering of large-scale distributed computer systems.
Education and early career
Ghemawat studied at
Cornell University and the
Massachusetts Institute of Technology (MIT).
[3] He obtained a PhD from MIT in 1995, with a dissertation titled, The Modified Object Buffer: A Storage Management Technique for Object-Oriented Databases. His
advisors were
Barbara Liskov and
Frans Kaashoek .
[6]
Before joining Google, Ghemawat worked at the
DEC Systems Research Center . There he began his long-time collaboration with
Jeff Dean , who worked at another
DEC research lab nearby. Their work at DEC included a
Java compiler and a
system profiling tool .
[5]
Career at Google
After DEC was acquired by
Compaq , many of its researchers left the company. Dean took a position at the newly founded search-engine company
Google , and was joined by Ghemawat in 1999. The two began working on Google's core infrastructure, making improvements to cope with the search engine's rapid growth in users in the early 2000s.
[5]
Ghemawat's work at Google includes:
Original design of
Protocol Buffers , an open-source data interchange format.
MapReduce , a system for large-scale data processing applications.
Google File System , is a proprietary distributed file system developed to provide efficient, reliable access to data using large clusters of commodity hardware.
Spanner , a scalable, multi-version, globally distributed, and synchronously replicated database.
Bigtable , a large-scale semi-structured storage system.
LevelDB , an open-source on-disk key-value store.
TensorFlow , an open-source machine-learning software library.
Service Weaver , an open-source framework for writing distributed applications.
Awards and honors
Ghemawat was elected to the
National Academy of Engineering in 2009,
[2] and to the
American Academy of Arts and Sciences in 2016.
[7] In 2012, he and Dean received the
ACM Prize in Computing for their work on internet infrastructure,
[2]
[3]
[4] and the ACM
SIGOPS Mark Weiser Award .
