Carnegie Mellon Computing Expert Manuel
Blum Elected to the National Academy of Sciences
Manuel Blum, Carnegie Mellon University's Bruce Nelson professor
of computer science, and a leader in the world of theoretical
computing, has been elected to the National Academy of Sciences,
one of the highest honors that can be accorded to a U.S. scientist
or engineer. Blum is one of the founders of computational complexity
theory, work that has also had applications to cryptography and
program checking. He came to Carnegie Mellon as a visiting professor
in 1999 after a distinguished career at the University of California
at Berkeley where he received an A.M. Turing Award, the highest
honor in computing, in 1995. He received Carnegie Mellon?s Nelson
Chair in the fall of 2001. Blum?s work has developed around a
single unifying theme--finding positive, practical consequences
of living in a world where all computational resources are bounded.
He showed that secure business transactions and pseudo-random
number generation are possible because all computational devices
have finite resources. Today he is working on the Completely Automated
Public Turing Test, which is used by Yahoo to ensure that registrants
to Web sites are humans and not robots.
Blum attended the Massachusetts Institute of Technology where he
received his bachelor?s, and master?s degrees in electrical engineering
in 1959 and ?61, and a doctor?s degree in mathematics in 1964. His
election to the Academy brings the number of Carnegie Mellon members
to seven. The others include John R. Anderson, Stephen E Fienberg,
James McClelland, Dana Scott, Robert Griffiths and Lincoln Wolfenstein.
The National Academy of Sciences was founded in 1863 to advise
the government on the scientific issues that frequently pervade
policy decisions. The Academy and its sister organizations -- the
National Academy of Engineering, the Institute of Medicine, and
the National Research Council-- 0work outside the framework of government
to ensure independent advice on matters of science, technology,
and medicine.
