Ronald GrahamProf/Comptr Info Sci, Computer Science and Engineering Computer science, Internet routing, and mathematics, including combinatorics, number theory, graph theory, discrete and computational geometry. Professor Graham is one of the world's bestknown mathematicians, computer theorists, and technology visionaries. In math, he pioneered worstcase analysis in scheduling theory, online algorithms, quasirandomness, and Ramsey Theorya branch of pure math that states that complete disorder is impossible. Graham is in the Guinness Book of World Records for using (in 1977) the largest number ever in a mathematical proof (so large, there isn't even a notation for it), now known as "Graham's number." He is a leading authority on mathematics great Paul ErdÃ¶s, and his Ph.D. thesis on 20 number theory developed into a lifelong interest in cryptography.During his long career at AT&T (see bio), Graham's work on "hard problems" in mathematics led him to focus on the complexity of routing milions oftelephone calls. And his work on routing was influential in t he earlyarchitecture of the Internet, as well as the vision of "anywhere/anytime access to the wireless Web" pursued by Cal(IT)2 where he serves as Chief Scientist. Today Graham sits on the Board of Directors of a company that is synonymous with Web server technologyAkamai.
