Manuel Blum (Caracas, 26 April 1938) is a Venezuelan computer scientist who received the Turing Award in 1995 "In recognition of his contributions to the foundations of computational complexity theory and its application to cryptography and program checking".[2][3][4][5][6][7][8]
Contents
Education[edit]
Blum was educated at MIT, where he received his bachelor's degree and his master's degree in EECS in 1959 and 1961 respectively, and his Ph.D. in mathematics in 1964 supervised by Marvin Minsky.[1][7]
Career[edit]
He worked as a professor of computer science at the University of California, Berkeley until 1999. From 1999 to 2018, he was the Bruce Nelson Professor of Computer Science at Carnegie Mellon University, where his wife, Lenore Blum,[9] was also a professor of Computer Science. In 2002 he was elected to the United States National Academy of Sciences.
He and his wife resigned from CMU in 2018 to protest against sexism.[10]
Research[edit]
In the 60s he developed an axiomatic complexity theory which was independent of concrete machine models. The theory is based on Gödel numberings and the Blum axioms. Even though the theory is not based on any machine model it yields concrete results like the compression theorem, the gap theorem, the honesty theorem and the Blum speedup theorem.
Some of his other work includes a protocol for flipping a coin over a telephone, median of medians (a linear time selection algorithm), the Blum Blum Shub pseudorandom number generator, the Blum-Goldwasser cryptosystem, and more recently CAPTCHAs.[11]
Blum is also known as the advisor of many prominent researchers. Among his Ph.D. students are Leonard Adleman, Dana Angluin, Shafi Goldwasser, Mor Harchol-Balter, Russell Impagliazzo, Silvio Micali, Gary Miller, Moni Naor, Steven Rudich, Michael Sipser, Ronitt Rubinfeld, Umesh Vazirani, Vijay Vazirani, Luis von Ahn, and Ryan Williams.[1]
